Nagios Support Forum

Hi,

I'm having some issues with the Check_esx3.

with the wizard of vmware i have added some ESXi. The plugin collect data with no problem, and get all the metrics for CPU, MEM, datastore and others. And diferent measurement of this metrics (%, MHZ, etc..) I can see the Performance Graph with no problem.

The issue happen when i specific a value from the metric to collect. For example when i insert in the SUBCOMMAND (-s) value for CPU metric "usage" i get the specific value for CPU_Usage and i define with this the notifications with the Critical and warning parameters to send emails. But when i do this i loss the performance graph for this variable. But when I leave in blank the SUBCOMMAND value, I recover the performance graph.

why is this happening?

Thanks a lot!

When RRDs are generated, there are done so for a specific number and type of metrics. When you change metrics for a check, the RRD will no longer populate. You usually have to rename/remove the corresponding RRD and let a new one get generated after the second check.

If you are having issues with RRDs after you changed metrics, you will find the related errors in /usr/local/nagios/var/perfdata.log.

Hi,

If i see the perfdata.log i see this:
2013-01-03 13:00:29 [12161] [0] *** TIMEOUT: Timeout after 5 secs. ***

And i look in this directory /usr/local/nagios/share/perfdata/"hostname" and i find the .rrd and .xml files.
What happen if i delete this file for a specific services? this is what you say that its going to generate again?



when y left the subcommand in blank the service bring me all metrics (e.g cpu %, cpu mhz etc..) there is a way to define alarm for cpu % and get all those metric to?
or I have to make individuales services for each one of the metric and define notficación for each one??


Thanks for your help!

Try making a run through of this document, due to the errors we can see this should solve your issue:

In answer to your question about deleting RRD's yes, once you remove them you will lose the past performance data forever, but they will be regenerated.

In regards to adding more metrics, how do you have your command defined? Also, did you run the Esx Monitoring wizard to set these checks up? The wizard should allow you to choose to monitor everything the plugins allow.

Thanks i will look the document.

First time i run the vmware wizard to add the ESX's, it brought all the metrics the respective Performance Graph. Then I was looking in how to configure warnings and critical parameters for notification's. Then I look to the specific $ARG for the SUBCOMMAND of the comand. This because i dont know how to set the W and C for the metrics when was all added under one services with the wizard.

Thats mean, when i add one ESX the wizard under "MEM" give me overhead, swapped and usage. When the command just give the posibility to enter in the Args just one W and C treshold.

Hope im clear with the explanation.


in resume i want to have all the metric for an ESX service (CPU, MEM, etc..) and generate C and W notifications (emails) with the metrics threshold (usage, swap, MHZ etc...)


Thanks a lot again!

If you want to separate these you can by adding sub-commands with the -s flag items with the + are subcommands

I would like to continue with this topic with this:

when i add an ESX for Memory the plugin get me "CHECK_ESX3.PL OK - mem usage=5761.18 MB (4.39%), overhead=312.89 MB, swapped=0.00 MB, memctl=0.00 MB"

This when the command is this:
./check_esx3.pl -H "HOSTNAME" -f "File" -l "MEM" -s "" -C -W

But how i configure the alarms (-C and -W) because the command get me 4 variables in diferent measures.

Thanks,

Looking at the usage information for the plugin, the warning and critical thresholds are measured in MB or %. The metric effected by the thresholds are overall memory (as this is an esx host check). If you want to measure the individual vms, you would have to specify the -N switch with the vm_name.

You would need to specify a subcommand ie

Ok,

But for examples for an ESXi critical and warning definition i need to made this command:

./check_esx3.pl -H "HOSTNAME" -l "MEM" -s "usage" -w 80 -c 90

But the thing is that with this command i lose al the other metric's to see... the overhead, swapped and memctl. And i need those metrics to.

I try then addind one by one adding new services with diferent subcommand (e.g: -s swap). But doesn't work.
