Memory Utilization plugin for windows server

[deek]

Hi Team ,

Currently we are monitoring the memory utilization of windows server using check_nrpe as shown in the below screenshot . The alerting threshold is setup as MaxWarn=90% MaxCrit=95% .

I wanted a warning / critical alert when there is only 2 GB space available . So is there a way to give the alerting threshold value in GB .

Hi Deek,

We have a check the library on our knowledgebase with some example, NSClient checks that are pretty useful.

https://support.nagios.com/kb/article/m ... free_value

In this case, the example arguments would be (critical if less than 2GB):

Code: Select all

./check_nrpe -H 10.25.14.10 -c check_memory -a type=physical 'warn=free<4G' 'crit=free<2G'

Let me know if that's going to work for you. Also, some more details on the NSClient check_memory query available at:

Hi ,

I have one more question . This plugin is really good but it displays only the used GB . Is there a way it can display the available / Free GB as well.

HI deek,

After reviewing the doc on this one, I don't see an option to change that behavior. Here's a link to all the available options for check_memory.

Let us know if you have further questions.

So is there a way by using the plugin checkMem we can set the warning and critical thresholds in GB ?

Hi Deek,

You can set the free memory to use any of the following metrics, that part can be adjusted

Free memory in bytes (g,m,k,b) or percentages %

https://docs.nsclient.org/reference/win ... ory_filter

Or used memory:

used Used memory in bytes (g,m,k,b) or percentages %

[deek]

Thanks for that .

And is there a way to only alert when the "available memory is less than 1 GB and less than 5% memory consumed" . I know its complicated .

I think this should do it:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -2 -H X.X.X.X -c check_memory -a type=physical 'crit=free<1G or used<5%'

Or:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -2 -H X.X.X.X -c check_memory -a type=physical 'warn=used<5%' 'crit=free<1G'
