Memory plugin issue on Windows server

[jyoti22]

Hi Team,
On 1 of windows box, used memory is showing 74% it means free memory is 26%. Still on Nagios XI, parameter is in critical alert.
Please find attached screenshot from server and XI output. Kindly help me to resolve it.

Regards,
Jyoti

How much memory total does the machine have? Depending on how your check is running, it may be including swap which would throw your numbers off a bit.

Can you show us the service definition for the memory check?

One thing to note as well, XI checks every x minutes based on your check_interval, it could be possible that it went down after Nagios had checked it.

Please find attached screenshot of total server memory and service definition.

I found this in nsclient++ forum.
"check_nt does not check physical RAM it checks committed bytes"

To get what you want, you will have to use the check_nrpe command using the check_memory option to get the physical memory usage.

The link is of no use...Solution not given there

Instead of using the check_nt command, you would have to use the check_nrpe plugin and the CheckMEM command to get the physical memory using the example below.

Code: Select all

command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -c CheckMEM -a 'type=physical' MaxWarn=80% MaxCrit=90%

If you need help configuring the NRPE side of the NSCLient++ agent, take a look at this document for help.
