Re: [Ganglia-general] Changing sample rate

2015-03-04 Thread Karol Korytkowski 
Hi Fabio,

I think you have to change this in gmetad.conf:
RRA:AVERAGE:0.5:1 :5856#  1 day @ 15 second res

Read Monitoring with Ganglia ebook, it's well explained there.

 Hi everyone,
 I've been using Ganglia installed through Ambari on an hadoop cluster. Now
 we want to change sampling rate from 15 seconds to something lower, say 5
 secs.
 We edited the gmetad.conf as specified in the comments, obtaining
 something like:
 data_source my cluster *5* localhost  my.machine.edu:8649  1.2.3.5:8655
 We restarted all the ganglia services and we are pretty sure it is now
 using the updated config file, but the sampling rate is still 15 seconds.
 We also tried to change the collection_group-collect-every to 5 seconds
 too, but with the same old behavior.

 Is there something we may be missing?

 Thanks

 Fabio

Re: [Ganglia-general] gmond's on same multicast port won't communicate at same time

2014-09-04 Thread Karol Korytkowski 
I'm curious as of what the correct answer would be, but..

We have similar problem (forgive if not, I just scanned through your
email), and some kind of solution was to use different data_source
(@gmetad) for each of such issues and give them same cluster { name =
 }  (@gmond).

I think this has something to do with multicasts between switches, but so
far noone has looked into this..

 Here's my scenario.  I've got some systems that were happily reporting
 in ganglia and they had to have their OS'es rebuilt.  They're now
 running RHEL 6.5.

 I can be on my gmetad server, and tcpdump looking for packets from host1
 and host2 and only see one.  Both host1  host2 are running with the
 exact same gmond.conf configuration... same port.   They both appear to
 be running correctly.  But one shows more activity than the other when I
 run a 'netstat -an | grep 8204'  (8204 is the port they run on).   When
 I run 'telnet localhost 8204' on them both, they show me all the xml
 data that they're sending out.  Both gmond clients are sending their
 multicast traffic across the same network also.

 But the server only seems to want to pick up one at a time.  In my
 gmetad.conf file, the data_source line for this port only has two
 entries... host1:8204 host2:8204 (and these hosts are the fully
 qualified domain names... on the same network that the two hosts are
 sending their multicast across on).   I can have both gmond's running
 but only one seems to generate all the tcp  connections (like you see
 via 'netstat -an | grep 8204') where the other one doesn't.  The one
 that does is the one I see on my gmetad server.

 On the gmetad server, I can run tcpdump on the appropriate network
 interface and look for traffic coming from my host1 and host2.  I can
 only see one at a time.  I should see both my hosts.  I make that
 assumption because I can run that same type of command on another port
 for other hosts that are on it and get back results lots of
 different hosts showing up because I have lots of hosts on that
 particular port.

 Here's what I'm guessing are the relevant entries from the gmond.conf
 file on my two hosts in question:

 /* The host section describes attributes of the host, like the location */
 host {
location = unspecified
 }

 /* Feel free to specify as many udp_send_channels as you like.  Gmond
 used to only support having a single channel */
 udp_send_channel {
#bind_hostname = yes # Highly recommended, soon to be default.
 # This option tells gmond to use a source address
 # that resolves to the machine's hostname.  Without
 # this, the metrics may appear to come from any
 # interface and the DNS names associated with
 # those IPs will be used to create the RRDs.
mcast_join = 239.2.11.71
port = 8204
ttl = 1
 }

 /* You can specify as many udp_recv_channels as you like as well. */
 udp_recv_channel {
mcast_join = 239.2.11.71
port = 8204
bind = 239.2.11.71
 }

 /* You can specify as many tcp_accept_channels as you like to share
 an xml description of the state of the cluster */
 tcp_accept_channel {
port = 8204
 }


 Any insight would be appreciated.  :)

 Thanks,
 -chris

Hi Wendy,

this is mysql rather than ganglia problem. You should probably see this:
