[Openstack] Question to how to write a Plugin for Quantum
Dear All: I'm trying to write a plugin for quantum to integrate my own load balancer such that I can replace openstack's. However, I'm stuck on how to make the migration. I'm just wondering if anybody has the previous experience on this or any help would be highly appreciated.

On the wire (including all the protocol headers) or to user level (after all the protocol headers)? That you were seeing 95 Mbit/s suggests user level but I'd like to make certain. GRE adds header overhead, but I wouldn't think enough to take one from 95 down to 26 Mbit/s to user level. I would suggest looking at, in no particular order: *) Netstat stats on your sender - is it retransmitting in one case and not the other? *) per-CPU CPU utilization - is any one CPU on the sending, receiving or intervening iron saturating in one case and not the other? and go from there. I'm guessing your tests are all bulk-transfer - you might want to consider adding some latency and/or aggregate small-packet performance tests. happy benchmarking, rick jones the applicability varies, but attached is some boilerplate I've built-up over time, on the matter of why is my network performance slow? PS - the beforeafter utility mentioned is no longer available via ftp.cup.hp.com because ftp.cup.hp.com no longer exists. I probably aught to put it up on ftp.netperf.org... Some of my checklist items when presented with assertions of poor network performance, in no particular order, numbered only for convenience of reference: 1) Is *any one* CPU on either end of the transfer at or close to 100% utilization? A given TCP connection cannot really take advantage of more than the services of a single core in the system, so average CPU utilization being low does not a priori mean things are OK. 2) Are there TCP retransmissions being registered in netstat statistics on the sending system? Take a snapshot of netstat -s -t from just before the transfer, and one from just after and run it through beforeafter from ftp://ftp.cup.hp.com/dist/networking/tools: netstat -s -t before transfer or wait 60 or so seconds if the transfer was already going netstat -s -t after beforeafter before after delta 3) Are there packet drops registered in ethtool -S statistics on either side of the transfer? Take snapshots in a manner similar to that with netstat. 4) Are there packet drops registered in the stats for the switch(es) being traversed by the transfer? These would be retrieved via switch-specific means. 5) What is the latency between the two end points. Install netperf on both sides, start netserver on one side and on the other side run: netperf -t TCP_RR -l 30 -H remote and invert the transaction/s rate to get the RTT latency. There are caveats involving NIC interrupt coalescing settings defaulting in favor of throughput/CPU util over latency: ftp://ftp.cup.hp.com/dist/networking/briefs/nic_latency_vs_tput.txt but when the connections are over a WAN latency is important and may not be clouded as much by NIC settings. This all leads into: 6) What is the *effective* TCP (or other) window size for the connection. One limit to the performance of a TCP bulk transfer is: Tput = W(eff)/RTT The effective window size will be the lesser of: a) The classic TCP window advertised by the receiver. This is the value in the TCP header's window field shifted by the window scaling factor which was exchanged during connection establishment. The window scale factor is why one wants to get traces including the connection establishment. The size of the classic window will depend on whether/what the receiving application has requested via a setsockopt(SO_RCVBUF) call and the sysctl limits set in the OS. If the receiving application does not call setsockopt(SO_RCVBUF) then under Linux the stack will autotune the advertised window based on other sysctl limits in the OS. Other stacks may or may not autotune. b) The computed congestion window on the sender - this will be affected by the packet loss rate over the connection, hence the interest in the netstat and ethtool stats. c) The quantity of data to which the sending TCP can maintain a reference while waiting for it to be ACKnowledged by the receiver - this will be akin to the classic TCP window case above, but on the sending side, and concerning setsockopt(SO_SNDBUF) and sysctl settings. d) The quantity of data the sending application is willing/able to send at any one time before waiting for some sort of application-level acknowledgement. FTP and rcp will just blast all the data of the file into the socket as fast as the socket will take it. Scp has some application-layer windowing which may cause it to put less data out onto the connection

I have some questions on the networking part which mentioned below. Please
help.
I am using ubuntu server 12.10.
I am using the flatmanager option, as both of my nodes have only single
nic.
first node is running all the services except the nova compute.
only nova compute is running on the second node.
I have cretated br100 on both the nodes and bridged to em1.
I have one DHCP running external on the same network.
All went good.
The problem i can see is my VM's are getting ip from the external DHCP
server, but the Horizon UI is showing different ip. please let me know if
anymore info required.

Personally, I would guess that for ephemeral drives they use either no RAID at all or RAID10, probably none though, especially as they don't advertise any reliability for these drives. The issue of rebuild performance in parity-based RAID configs and the effect it would have on guest performance would be a significant consideration.

I've been playing around with this in Devstack, and so far I've found that whilst I can create a non-public flavor and add access to a specific tenant (which I take to show that the extension is loaded properly) - It doesn't show up in the result of flavor-list, even for tenants that have access to it, or if the user has the admin role - Providing I know the ID of the flavor I can get details of it with nova flavor-show even if the tenant hasn't been added for access - Providing I know the ID of the flavor I can create an instance to use it even if the tenant hasn't been added for access Looking in the code I can't see any support in the API to ever list private flavors, or to validate the access to a flavor, but maybe I'm looking in the wrong place. Has anyone else been using this extension ?

[Openstack] New to OpenStack - question Swift+Keystone Horizon
Hi
I have just started to take a look at OpenStack (especially Swift, as this is
what is most needed for a case I am investigating).
So far I have managed to get a Swift node up and running (all-in-one) on
Ubuntu, but for some reasons I have been asked to take at look at the RedHat
preview-implementation of the Folsom release.
Since Nova and the other parts not are needed, I would prefer not to install
those parts... But will Horizon still be able to work - just with Swift and the
underlying identity service based on keystone ?
I have tried the RedHat approach, and Keystone is up and running. I then tried
to install and configure Horizon according to the RedHat instructions (and
installed Swift afterwards). But whenever I log on to the Horizon interface, I
get an internal server error page back.
Sine I don't know whether Horizon will run on such a limited setup (and I have
not been able to locate information about it), I don't know whether it could be
a bug in the RedHat implementation - or it simply is an unsupported setup...
Regards
Brian

Re: [Openstack] New to OpenStack - question Swift+Keystone Horizon
Horizon's list of required services includes Nova, Glance and Keystone. At
present no work has been done to make it run with a Swift + Keystone (only)
configuration. That said, it's not impossible. The easiest route would likely
be to unregister all of the Nova and Glance-related panels in the existing
System and Project dashboards (this can be done using Horizon's
customization_module setting, though documentation for it is minimal), and
provide a custom user_home function that directs users to the Containers
(e.g. Swift) panel upon login.
In general as long as you don't ever touch any of the panels that try to make
API calls to Nova or Glance you can avoid having to run those services.
Unfortunately, *a lot* of the panels *do* make calls to those services. The
Swift Containers panel does not, though, so it can be done.
Keystone is absolutely required, though, along with proper Swift + Keystone
auth integration. That part is critical.
All the best,
- Gabriel

Re: [Openstack] Question about Disk Setup of Nova Compute Node
Gui, Here is my current plan on the table (I have not started the action yet): Go for RAID 5, because if a VM happen to rely on data on a local disk, I can avoid the situation he notice a bad luck. (if I use JBOD, then I have to say sorry to her, my customer, in such case) IMO, it's always a tradeoff. I am just very curious how Amazon configures its EC2 hardware.

Good luck getting that information! You might be able to make some guesses from benchmark info though, there is plenty around. This post from Scalyr takes a great all round look at EC2 IO performance, and it's pretty recent data: http://blog.scalyr.com/2012/10/16/a-systematic-look-at-ec2-io/ . Personally, I would guess that for ephemeral drives they use either no RAID at all or RAID10, probably none though, especially as they don't advertise any reliability for these drives. The issue of rebuild performance in parity-based RAID configs and the effect it would have on guest performance would be a significant consideration. Having said that, it's difficult to find reports of ephemeral drive failures, and Amazon don't quote any failure rates themselves. -- Cheers, ~Blairo ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

Thanks a lot guys.
I've solved my issue for your advice. :)
It was caused by Port_id and Nova.conf of compute node.
Now I have to deploy swift and lunch vm instance using iso.
I'm appreciate if you answer my foolish question.

Re: [Openstack] Question: how to make floating ip pools?
Hello,
If you don't mind me asking, how did you create/launch the VM instance
using the Cirros image? Did you use Horizon or command line? If command
line, can you please share the commands you used?
Thank you,
Ahmed.

I've solved my issue for your advice. :)
It was caused by Port_id and Nova.conf of compute node.
Now I have to deploy swift and lunch vm instance using iso.
I'm appreciate if you answer my foolish question.
Best Regard.

Hello,
I am doing below guide.

guide/blob/VLAN/2NICs/OpenStack_Folsom_Install_Guide_WebVersion.rst
At Ch.11 Your First VM, I've encountered a error.
My question is:
1) What is the $put_id_floating_ip and $put_id_vm_port?
e.g.) $ quantum floatingip-associate $put_id_floating_ip
$put_id_vm_port
put_id_floating_ip is your floating id. below command show your
floatingip.

Re: [Openstack] Question: how to make floating ip pools?
Thank you for sending the link to your script, much appreciated. Can you please shed some light when to use the —tenant_id=admin and --tenant_id=proj_one (a tenant other than admin tenant) when issuing the quantum command, e.g. creating external/internl network, sub-net, launching VM, etc. In your script, do you assume the user has set OS_TENANT__NAME to admin or proj_one?

Hello,
I am doing below guide.
https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/VLAN/2NICs/OpenStack_Folsom_Install_Guide_WebVersion.rst
At Ch.11 Your First VM, I've encountered a error.
My question is:
1) What is the $put_id_floating_ip and $put_id_vm_port?
e.g.) $ quantum floatingip-associate $put_id_floating_ip $put_id_vm_port
put_id_floating_ip is your floating id. below command show your floatingip.
# quantum floatingip-list
+--+--+-+--+
| id | fixed_ip_address | floating_ip_address
| port_id |
+--+--+-+--+

| 3be818d4-b4e9-4e9f-b42f-66701bd57b47 |
+--+--+-+--+
$put_id_vm_port is that your vm's port that attached your network. when your
instance and floatingip is like below
root@control:~# nova list
+--+---++--+

you can associate floatingip to instance like this.
# quantum floatingip-associate abfb3889-32f4-4854-bd61-6fb37e406faa

2) How can I know whether controller node and compute is connected?
$ nova-manage service list
command show that what nova services is running.
The status of Controller node - I can't see any resources.

[Openstack] Question about nova-api log message entries
Hello, I am running into an issue creating a VM instance (RPC message timeout in nova-network). I have a few questions about the following entires in nova-api.log file: 1) 2012-11-18 15:50:27 DEBUG nova.openstack.common.rpc.amqp [-] Making asynchronous call on network ... from (pid=1688) multicall /usr/lib/python2.7/dist-packages/nova/openstack/common/rpc/amqp.py:351 2) 2012-11-18 15:50:27 DEBUG nova.openstack.common.rpc.amqp [-] MSG_ID is 4b1f8e549f1448589d9d35b7eb4b6364 from (pid=1688) multicall /usr/lib/python2.7/dist-packages/nova/openstack/common/rpc/amqp.py:354 3) 2012-11-18 15:50:28 DEBUG nova.compute.api [req-f2b4df1f-6c29-48dc-991b-93fb5eb29d08 ce016bb05df949ebbafcc7c165359d7c ce1e819636744dc680fa5515f6475e87] Going to run 1 instances... from (pid=1688) _create_instance /usr/lib/python2.7/dist-packages/nova/compute/api.py:490 4) 2012-11-18 15:50:28 DEBUG nova.openstack.common.rpc.amqp [-] Making asynchronous cast on scheduler... from (pid=1688) cast /usr/lib/python2.7/dist-packages/nova/openstack/common/rpc/amqp.py:376 Questions: - Is log message 1 and 4 related to nova-api sending a message to nova-network and nova-scheduler through the rabbitmq queue server? - I have a two node setup, one controller-node (on which no nova-compute running) and one compute-node (on which nova-compute is running). Who/which service on which node is printing log message 3. The reason I ask is because log message 3 is prefixed with nova.compute.api, but I feel at this point no message has reached nova-compute service on compute-node. - The MSG_ID in log message 2 pertains to which message? - Out of curiosity, what is the difference between Making asynchronous call (log message 1) vs. Making asynchronous cast (log message 2). Any info in understanding the log messages would be highly appreciated.

Re: [Openstack] Question about pv mode on compute and network
Hi, Sorry I missed this, I am still behind on my email. In the current model every XCP node gets a VM with nova-compute running on it, and it must be a linux PV VM. That node does several management tasks. For example, with raw images, it will stream the image into a VDI attached to that VM. In the current world, you need to be a PV VM for the hotplug of that volume to be allowed. So, to cut a long story short, yes, it needs to be a PV VM. I noticed some storage questions. Generally you should have a single local SR of type EXT on each of your XCP hosts. Hopefully that is all covered in the Admin guide. Let me know if anything is confusing, and I will update the guide to help clarify things. If you want shared storage you need to look towards using Cinder. So attaching volumes, doing boot-from-volume, and other such things. Right now we have support for things that produce iSCSI targets, and some NFS shared storage support is just dropping into Grizzly over the next week or so. I hope that helps, John -Original Message- From: openstack-bounces+john.garbutt=citrix@lists.launchpad.net [mailto:openstack-bounces+john.garbutt=citrix@lists.launchpad.net] On Behalf Of Egoitz Aurrekoetxea Aurre Sent: 04 November 2012 10:32 To: openstack@lists.launchpad.net Subject: Re: [Openstack] Question about pv mode on compute and network or just I nova-compute and nova-network -- 1 nova-compute and nova...

Hi, all Recently, I find out that when the instance with some metadata or system_metadata was deleted, but instance_metadata and instance_system_metadata these two tables are still keep the metadata and system_metadata deleted=0 (means these datas are not deleted).

Re: [Openstack] question about multi-host network configuration
Sure, we've been running in that sort of configuration since bexar. The only tricky part is that you need to make sure that you run nova-api-metadata on each nova-network server, and you need to make sure that floating IPs can get to the appropriate fixed addresses (ie if a fixed address is not routed from the nova-network instance where the floating address is served from). That last bit pretty much requires setting up something like ospf for route exchange between your nova-network servers. (fixed networks aren't pegged to one n-net instance or the other, so they can move over time) -nld On Mon, Sep 17, 2012 at 9:38 AM, Xin Zhao xz...@bnl.gov wrote: Hello, Our openstack cluster has 2 racks of physical nodes, I want to set up two openstack network service hosts, each serving one rack.

[Openstack] Question about undo delete in Swift with Object Version
Hi stackers, I'm trying to understand the object version feature in Swift. In the current implementation we can store multi-versions of the same object in Swift. However when you delete it from the container, the latest version is deleted and this is not recoverable, right? Is there any magic to restore the deleted version?

Re: [Openstack] Question for Quantum V2 subnet
Hi
Thank you for your comment.
I see. dual stack network need ipv4 and bunch of ipv6 prefix
(link-local, global, temporary global..) on one network.
The reason for this is because you can have multiple subnets on the same
L2 bcast domain. You can use ip aliasing in order to use multiple subnets on
one virtual nic. For example ifconfig eth0:1 a.b.c.d/24; ifconfig eth0:2
d.e.f.g/24
This means, It seems like vlan tagging?
Thanks!

In a dual stack deployment there may be a v4 and a v6 subnet on the same
network.
There's also the case that a service provider has a notion of a public
network, which is represented by a UUID. After a period of time, they may
run out of IPs in one subnet, and want to assign another subnet as well,
without forcing tenants to have to start using a new identifier for the
public network. Of course, the provider would be responsible for creating
L3 connectivity between the two subnets.
Others can chime in, but those where the two cases that I remember.

[Openstack] Question for Quantum V2 subnet
Hi all.
I have one question. I prepared devstack with Qauntum V2.
Now I can create Subnet for Network.
And I can add multiple Subnet for one Network. VM can use multiple
subnet for one virtual NIC?
Why quantum v2 can create multiple subnet for one Network?

Re: [Openstack] Question for Quantum V2 subnet
The reason for this is because you can have multiple subnets on the same L2
bcast domain. You can use ip aliasing in order to use multiple subnets on
one virtual nic. For example ifconfig eth0:1 a.b.c.d/24; ifconfig eth0:2

Re: [Openstack] Question for Quantum V2 subnet
In a dual stack deployment there may be a v4 and a v6 subnet on the same
network.
There's also the case that a service provider has a notion of a public
network, which is represented by a UUID. After a period of time, they may
run out of IPs in one subnet, and want to assign another subnet as well,
without forcing tenants to have to start using a new identifier for the
public network. Of course, the provider would be responsible for creating
L3 connectivity between the two subnets.
Others can chime in, but those where the two cases that I remember.

[Openstack] Question on hostname generation?
Hi all, I was wondering about the following case (and am not sure if its been addressed in folsom). At yahoo, instead of the default hostname that seems to be automatically established (ie 'server-XYZ.novalocal' was in essex) we were wondering if there is anything in folsom that say lets us override that generation with either a module (or a subclass) or a new function without having to patch nova code. Sometimes we want a default hostname of a different format (as probably do others) and I just am not sure if quantum is directing this default hostname, or if nova still is, or if its some mix of both (the metadata + cloud-init can affect the hostname as well, so perhaps the configdrive work should be the only one establish a 'real' hostname?). I have found the following pieces of hostname related code but am not sure if this is all the places that make hostnames :-) * https://github.com/openstack/nova/blob/master/nova/api/metadata/base.py#L109 Is this the only place nowadays?? Is there something in quantum also? Thx much, just trying to track this down. -Josh ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

[Openstack] Question on nova disk injection...
Hi all, Just some questions that I had about how nova is doing disk injection and such. I was noticing that it the main disk/api.py does a lot of tee, cat and similar commands. Is there any reason it couldn't just use the standard python open and write data and such. Is it because of sudo access (which is connected to rootwrap?), just wondering since it seems sort of odd that to write a file there a tee call has to be done with piped input, when python already has file operators and such...

Re: [Openstack] Question on nova disk injection...
Why couldn't nova just escalate pythons privileges to the super user when writing a file (thus allowing it to use python file writing functions and such). Then after it writes it could drop it back to down to some other user? That might make sense, idk, instead of having the disk injection act like a shell script which basically just emits a bunch of [tee, mv, touch, mkdir, cp] commands. I've done something like this for anvil, not sure if its useful here but who knows: https://github.com/yahoo/Openstack-Anvil/blob/master/anvil/shell.py#L70 On 6/5/12 2:50 PM, Russell Bryant rbry...@redhat.com wrote: On 06/05/2012 05:42 PM, Joshua Harlow wrote: Hi all, Just some questions that I had about how nova is doing disk injection and such.

Re: [Openstack] Question on nova disk injection...
Interesting, darn, that sorta makes it harder than it seems like it should be. Is there any pattern that we can follow for this that other programs use, do most other programs shell out as root, and expect there command sets to be restricted? Do other similar programs just assume that they are running as a user that won't need to be restricted? Java seems like it would have the same issue, but of course its threaded, I there any similar concept there of temporarily escalating privileges for a thread, performing some action, then reducing privileges? I wonder if eventlet could support something like this (or be modified to?). Anyone else know other ways of doing this that might be useful? The suggestions that involve RPC being one way.

Re: [Openstack] Question on nova disk injection...
Yun, The setuid bit is unnecessary, python can be launched by the root user. It would then drop privileges. For instance, the sshd daemon does not require a setuid bit, it is simply executed by root. It uses privilege separation and does the set(e)uid for users that login through it. Having a compiled program and a setuid bit destroys a number of the reasons why you would want to have this run as root. For one thing, if your daemon runs as root and drops to the 'nova' user, compromises within the context of running as the nova user cannot allow the daemon to be modified and re-executed. Without having any 'sudo' requirements, the nova user would be quite constrained, relative to the current situation. -- Eric Windisch On Tuesday, June 5, 2012 at 21:18 PM, Yun Mao wrote: Python is a scripting language. To get setuid work, you usually have to give the setuid permission to /usr/bin/python which is a big no no. One work around is to have a customized compiled program (e.g. from C), which takes a python file as input, do all kinds of sanity check, and switch to root user to execute Python. But in that case it's not that much more appealing from the rootwrap. my 2c.

Re: [Openstack] question about security
Generally I handle this by using a different eth device (or vlan) for the instance network. Then you make sure that no services on compute are listening on 0.0.0.0 If you have only one interface for example, you can run three vlans across it eth0:10 - public network public ip address for routing and floating ips and such. Nothing should listen here eth0:11 - management network 192.168.0.0/24 range Rabbit and mysql run on this network. All services (ssh, etc.) run here eth0:12 - vm network 10.0.0.0/8 range for vms. Nothing should listen here (except dnsmasq obviously) Vish On May 31, 2012, at 7:35 PM, William Herry wrote: We use FlatDHCP network mode, all thing work fine, instance has 10.0.0.x ip and 10.0.0.1 as gateway Our problem is that service(most time compute node) has little restrict from instance, which instance can see a lot opened port on service, I am thinking if this is a security problem restrict service on compute node not listen on 10.0.0.x ip is the way I can thing to solve this, any other ways?

We use FlatDHCP network mode, all thing work fine, instance has 10.0.0.x ip and 10.0.0.1 as gateway Our problem is that service(most time compute node) has little restrict from instance, which instance can see a lot opened port on service, I am thinking if this is a security problem restrict service on compute node not listen on 10.0.0.x ip is the way I can thing to solve this, any other ways?

[Openstack] Question about cloudfiles API
This question is probably more appropriate for the Swift mailing list,
but I could not figure out how to subscribe to that list, so it's going
here. I'm OK with moving it there, if someone can tell me how to get
subscribed, or if I'm in completely the wrong place, let me know.
I am attempting to evaluate Swift for our environment. I have set up a
Swift cluster using the ubuntu multi-server HOWTO and I can use the
commandline utilities to upload and download files. Now I need to do a
test using the Java API. I downloaded java-cloudfiles and I can't seem
to make it work. It fails at the login() step.
FilesClient client = new FilesClient(username, password,
authUrl, null, 1);
if (client.login())
{

This all works with the curl command using the same auth URL. I've got
the default user/password set up from the HOWTO.
Initially I suspected that the problem was due to the self-signed
certificate, but watching syslog on the primary proxy server, I don't
see any requests logged, but I do see a conversation happen on port 8080
with tcpdump. How can I troubleshoot this?
Thanks,

Re: [Openstack] Question on notifications
Yes, the publisher_id is servicename.host, so ya, you can determine the compute
host from that.

Hi all,

There seems to be the following key: publisher_id: compute.buildingbuild
(event is compute.instance.create.end)
It would seem the stuff after “compute” is the hostname, would that be correct,
or should the scheduler messages be intercepted, which as example has the
following:
weighted_host: {
host: buildingbuild,
weight: -1488.0
}
I would think the first practice would be right, since its from the compute
node instead of the scheduler, but would like some feedback :-)

Re: [Openstack] Question on notifications
Yes, correct, I thought you wanted the info as soon as the scheduler decided on
a host. create.end will only fire when the instance has been created.
And you're correct about the scheduler, but all schedulers will likely be a
derivation of FilterScheduler or simply have custom filters/weights. Simple and
Change will turn to filters/weights soon. Depends on your installation.

Re: [Openstack] question about keystone and dashboard on RHEL6
Diablo (at least for nova, glance, swift) is capable of using keystone there is however a lot of manual configuration needed, something that is on my list for complete when integrating keystone into my 2011.3 deploy per my blog post. All I can say at the moment is this is far from trivial, and finding documentation on this can be a problem (if anyone on the list could correct me on this, it would help massively and expidite my documentation of integrating keystone with nova glance on 2011.3) Cheers Davud On Wed, Apr 11, 2012 at 4:16 PM, Adam Young ayo...@redhat.com wrote: On 04/03/2012 09:25 AM, Russell Bryant wrote: On 04/02/2012 08:44 PM, Xin Zhao wrote: On 4/2/2012 6:35 PM, Russell Bryant wrote: On 04/02/2012 03:09 PM, Xin Zhao wrote: Hello, I am new to OpenStack and trying to install the diablo release on a RHEL6 cluster.

[Openstack] Question on wsgi rate limiting
Throughout the discussion on distributed rate limiting I've had the annoying feeling that I've heard this joke before. Basically, are we looking for our keys under the street lamp because the light is good rather than looking for them where they were lost? Has anyone studied the effectiveness of rate limitations implemented at this layer. From my experience with rate shaping discussions in IEEE 802.1 Data Center Bridging group I am concerned that the response time working this far up the stack will preclude effective rate shaping. Of course, if someone has studied this and shown it to be effective then this would be great news.

You make some good points about what is the appropriate level in the stack to do rate shaping, but I would just like to have a configurable, manageable and monitorable ratelimit/quota solution that doesn't seem like a giant hack :) Baby steps. -jay On 03/30/2012 01:23 PM, Caitlin Bestler wrote: Throughout the discussion on distributed rate limiting I’ve had the annoying feeling that I’ve heard this joke before.

Re: [Openstack] Question on wsgi rate limiting
Caitlin, I'm curious what were the use cases and concerns in DCB? If my memory serves me right (from rate limiting at L2 level) the main issues are guaranteeing QoS, effective bandwidth usage, fair allocation of memory buffer space. All of those goals damaged pretty badly if congestion occurs and any of the resources are exhausted (leading to indiscriminate packet loss, for lack of any other recourse). The use cases, at least the way as I conceive them for OS are very different. They're not intended to resolve resource constraints as a primary goal (though, that's definitely a secondary goal). As an example - issuing lots of Nova API calls is by itself not the problem - executing the downstream effects of what those requests trigger is whats being protected (access to DB, spawning VM's, Rabbit MQ message rates etc). For Swift, where pure bandwidth is a primary concern, and the primary resource being consumed - I imagine you're right. Some L2/L3 traffic shaping (and monitoring) would be advisable - but that's not to say that's the only resource. e.g. creating and deleting containers repeatedly will consume relatively little bandwidth, but will exert quite a lot of resource consumption on the back end. Rate limiting these API calls is probably prudent at the API layer.

Re: [Openstack] Question on wsgi rate limiting
Caitlin, alas, you missed my point. The intent of rate limiting API calls in OS goes well beyond limiting network traffic. It's intended to ensure that no one tenant/user consumes unduly high resources throughout the system. These resources are not just network bandwidth, but the myriad of resources involved in providing the service (DB access, replication activity (both CPU,mem and bandwidth). These have little to do with networking or quantum (though having quantum provide an API for bandwidth management would be cool). You might want to think of this functionality as API-Quota - rather than the traditional bandwidth only rate limits.
