how to set warning and critical thresholds for CPU VMWare?

[gornm565]

I started monitoring VMware ESX 6.0 host and it's now working successfully. However, I am not sure how to set the threshold for warning and critical alerts in the GUI in Core Config Manager. Let's say I wanted to alert warning at 85% CPU and to alert critical at 90%.

How would I do it?

If you run:

Code: Select all

# /usr/local/nagios/libexec/check_esx3.pl -h

You will see the built-in help for the plugin. You will notice it supports -w and -c arguments with thresholds described at http://nagiosplug.sourceforge.net/devel ... HOLDFORMAT

So you would need to add that in as needed to your plugin or service definition.

So to warn above 85% and for critical above 90%, would this be correct?

Doesn't look like that works. I did -w 4 -c 5, so it should alert if it's above 5%. But it's not alerting:

It could be that is you do not specify a sub command, it ignores the threshold settings.
If you want to generate an alert if the CPU usage if too high, add the following to $ARG3$

Code: Select all

-s usage

To specify usage as the subcommand and the thresholds will be used.

Code: Select all

 * cpu - shows cpu info
            + usage - CPU usage in percentage
                o quickstats - switch for query either PerfCounter values or Runtime info
            + usagemhz - CPU usage in MHz
                o quickstats - switch for query either PerfCounter values or Runtime info
            ^ all cpu info
                o quickstats - switch for query either PerfCounter values or Runtime info

Yes, that was it. Now it works.

That is good news. If you don't have any questions, shall I close and lock the post for you?
