Hello All,

We need the plugin to monitor the physical memory of the server.

Do we have any plugin than NRPE to monitor the physical memory remotely?

I have checked check_nt plugin , but it's showing everything including swap and virtual memory.

./check_nt -H <IP Address> -p 12489 -v MEMUSE
Memory usage: total:16291.39 MB - used: 10662.15 MB (65%) - free: 5629.25 MB (35%) | 'Memory usage'=10662.15MB;0.00;0.00;0.00;16291.39

Is there any way to filter the output to physical memory usage?

Thanks

You could enable the NRPEServer in your NSClient++ configuration. Then NSClient++ can service requests on modules such as CheckSystem, which can be filtered down to provide only metrics about the physical memory by leveraging the type argument of the check_memory module.

This documentation covers how to do all that within Nagios XI, but it is just as relevant for Nagios Core:

Here's some official Nagios Core specific documentation for such a setup in which the "NSClient++ via check_nrpe" section contains your exact solution for checking only the physical memory on a machine:

NCPA is another option though it doesn't fit your exact use case. Here's official documentation for monitoring Windows hosts with Nagios Core and NCPA:

Unfortunately, the closest your can get for your specific use-case is the memory/virtual metric. Not perfect, but it at least excludes swap.

To give an examples if you do enable NRPE on nsclient, see this post:

Hi Mcapra & Scott,

Thanks for the reply.

we know the NRPE can monitor the physical memory of the server and we are monitoring the servers via nrpe.

The requirement is any plugin like (check_nt) and other third party plugin other than NRPE to monitor the physical memory on the server.

please do the needful.

Thanks,
Simbu

As was mentioned before NCPA can do this as well

Also, via SNMP
