hello list, I'm trying to install ganglia-gmetad on centos 5.6. rrdtool is already installed and librrd is there. But for some reason when I go to install this package it doesn't see that it is.

Hi All, What is the best way to remotely monitor/administer a group of xen domUs across a network? We''re planning to deploy a few H/W servers with paravirtualized domUs. What are the best alternatives? What works and What doesn''t? Share your experiences.

What is the best way to monitor the total incoming / outcoming network traffic of CentOS server. I think that the solution is to monitor the network interfaces and to send SNMP packets to remote server. But is it possible? regards -------------- next part -------------- An HTML attachment was scrubbed... URL:

We run ganglia on a 35 node cluster (plus a few odds and ends). It seems pretty lightweight. I've just finished installing the latest versions at home on old slow 32-bit kit and it seems again to be very lightweight. You will need to install libconfuse and RRD though, the former comes as a tarball. You...

Hi Guy, I am trying to figure out how & where can i get the bandwidth usage utilization statistic info for all the VM, so in the end i will be able to use it for metering purpose.. Anyone got any idea ? Regards, Peter -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello everyone, I know this isn't strictly CentOS query, but I am hoping that someone here with more experience than myself might have some thoughts. I am trying to get a plugin working for Ganglia on a CentOS 5.5 box, in a testing environment. The plugin is for apache monitoring, called Ganglia-Logtailer. This plugin requires the executable /usr/bin/logtail in order to work. The only packages that have this executable, that I have been able to find, is part of the epel-testing repository in...

Hi All, is there any tools/mods for apache2 which are you using to monitor the load of every virtual host? (e.g. mod_proctitle) thanks -- Sergey Smirnov email/xmpp: Sergey.A.Smirnov at Gmail.com

Hi, I am trying to create a report across all my KVM hypervisors using libvirt API and I need some assistance in figuring out the right API calls. My report will contain the total available memory, CPU, disk across all hypervisors, versus the amount used by the virtual machines. This report will help figure out if we are running low on hypervisor disk, CPU or memory and if we need to add more. I

...DT In this Gluster for Geeks technical webinar, Craig Carl, Senior Systems Engineer, will explain and demonstrate how to monitor your Gluster cluster for availability and performance. Topics covered will include: *what services and logs to watch *how to run baseline performance testing *how to use Ganglia for ongoing performance monitoring Craig will demonstrate how to use Ganglia to collate performance data from across a Gluster cluster and present it in a usable format. We will spend a little time discussing why using averages and ignoring standard deviation can result in very misleading results....

Hi Is it possible to have rpmforge for both architectures? Currently is only for 64bit, but I need some libraries 32bit (rrdtool) to install ganglia.

Hi! I am trying to to ask the packagers from repoforge for updated packages of ganglia and rrdtool and i got no answer on their mail list.. Does anyone have idea if repoforge is still active? Thanks! Adrian

...low agents on each of your KVM hypervisors: http://host-sflow.sourceforge.net/ The Host sFlow agent is a lightweight daemon that links to the libvirt library on the hypervisor and sends hypervisor and VM metrics using the sFlow protocol to a central collector. You could use an sFlow analyzer like Ganglia to record and display the metrics. http://blog.sflow.com/2012/01/using-ganglia-to-monitor-virtual.html Alternatively, you could use the sflowtool to convert sFlow to text and write a Perl/Python/Awk... script to generate your report. http://blog.sflow.com/2011/12/sflowtool.html Are you also usi...

Hi Sorry for the silly question, but is it safe to build packages, like rpms, in virtual machines (virtualbox) and use this packages in real machines? Some of these machines are CentOS and others ares Opensuse. I need to build (or would be very useful to have) Ganglia 3.1.x Thanks Marcelo

Is there a package I can get that will graph system resources such as CPU and disk I/O to an html file or something? Matt

...150 seconds.) The system monitoring shows a 10-20% system cpu overhead and the HPL run takes more than 200 secs. After running "echo 3 > /proc/sys/vm/drop_caches" the system performance goes back to normal with a run time at 150 secs. I''ve created an infographic from our ganglia graphs for the above scenario. https://dl.dropboxusercontent.com/u/23468442/misc/lustre_bc_overhead.png Attached is an excerpt from perf top indicating that the kernel routine taking the most time is _spin_lock_irqsave if that means anything to anyone.

Hello, Recently I''ve received some complaints that there is excessive but intermittent latency of network traffic to domUs on some of my servers. Upon investigation it seems that on some servers, indeed traffic is occasionally delayed by up to 140ms where something like 5ms RTT would be expected. The average RTT is not unusual; since this is only occasional packets it only affects the

Hi all, I have a test lab installed over an ESXi 5.1 host that contains 5 CentOS vm guests. I would like to monitor CPU, RAM and Network for these vm and ESXi host. Zabbix and Nagios are too to accomplish this task. Does anyone know any lightweight openosurce soft to do this?? Thanks.
