Re: [Openstack] [Ceilometer][Healthnmon]

[Doug Hellmann]

The work to merge ceilometer and healthnmon hasn't made much progress, yet.

The ceilometer team is working on collecting information about CPU and RAM
utilization for triggering alarms for Heat. That work is schedule for the
havana release, and is moving along nicely. We could use some help with
code reviews, but I think the overall design is worked out.

Not that I am aware of, Ceilometer is just getting Alarming
functionality.

Ceilometer is getting alarms this cycle. Heat will start using
them for autoscaling (cpu/mem stats).

[claudio marques]

Hi all
I think that we are all (people working with ceilometer), trying to figure out 
how to get the system actual data metrics from VMs.Do we need to install 
Healthnmon in order to get them? (because ceilometer as Julien already said, 
can't do it yet)

If you know how to retrieve the actual memory or disk used (rather than
allocated) by a VM by measuring from outside the VM, please enlighten
us. We (Ceilometer) don't know how to do that, that's why we don't do
it actually.

If you know how to retrieve the actual memory or disk used (rather than
allocated) by a VM by measuring from outside the VM, please enlighten
us. We (Ceilometer) don't know how to do that, that's why we don't do
it actually.

[Openstack] [Ceilometer][Healthnmon] Dealing with Performance/Monitoring Metrics

[Bruno Oliveira ~lychinus]

Dear stackers, please enlight me on something regarding Ceilometer/Healthnmon.

So far as I've read and setup, Ceilometer is intended to get metrics
for billing usage in larger interval polls. But so far, I've not seen
reports of Memory Utilization, Disk Space Utilization or other System
Utilization metrics. They're mostly "Memory Allocated", "Number of
vCPUs", and etc.

And checking out the Healthnmon projects, I can see that at the
very-low level, the mechanism is pretty similiar. I even spotted the
following:


"(...)But in another usage scenario, what if the users want to get the
relationship between different measurements? i.e. get all the
available measurements related to a specific VM instance, e.g. CPU
usage, disk IO usage, network information, storage volumes, …. In
Ceilometer it would require extra post-processing of the
'resource_metadata' to find all the measurements. While in Healthnmon,
the relationship is already in the data model so it's much easier.

The difference between the two data model may comes from that
Ceilometer is originally designed for metering, and Healthnmon is
designed for monitoring(...)"

https://wiki.openstack.org/wiki/Ceilometer/CeilometerAndHealthnmon


So, long story short, is technically possible for me to create metrics
to make the API show up system_usage_metrics instead of simply
system_allocated_metrics ?  (I guess I misunderstood, right?)

Could you please enlight the path for me ?

I'm not sure if I got it right... I have seen the blueprints of the
projects possibly unifying on Havanna release. But I'm looking for
something I can do (for usage metrics) right now (Grizzly).

Thank you in advance.
