Nagios Support Forum

Hi,

I have a problem with the check_mem. When I monitor a service memory with this check, it checks the virtual memory plus the physical memory and I just want to know the Virutal memory; is there a type of argument for this check to achieve this?

I have Nagios XI and I am using check_nrpe and later in the argument I call the check_memory

Thanks

Hello and welcome to the forum!

Are you using a windows system or Linux system? If Linux, can you attach the plugin you are using?

Hi!

Thank you for the welcoming

Well, I am using a Linux system and the plugin I am using is check_nt and the command line that I use is this one:

$USER1$/check_nt -H $HOSTADDRESS$ -s "$ARG1$" -p 12489 -v $ARG2$ $ARG3$ $ARG4$

Later in the argument 2 I am using "MEMUSE"

Thanks

To remove virtual memory you are going to want to use check_nrpe, see an example here
https://support.nagios.com/kb/article.php?id=774

I want to see just the virtual memory. For what I see in the page, NCPA can do it, isn't?

Yes, but NSClient can too, listed on that page in this section:
NSClient++ via check_nrpe

To only check the physical memory the type= argument can be used:
Command:

Code: Select all

./check_nrpe -H 10.25.14.10 -c check_memory -a type=physical 'warn=free<20%' 'crit=free<10%'

Output:

Code: Select all

OK: physical = 2.101GB|'physical'=3.89902GB;1.19991;0.59995;0;5.99956 'physical %'=64%;19;9;0;100

I did a new command and I wrote the next line:

$USER1$/check_nrpe -H $HOSTADDRESS$ -c check_memory -a type=virtual MaxWarn=$ARG1$ MaxCrit=$ARG2$

And it says:

CHECK_NRPE: Invalid packet type received from server.

I try it too with the type=physical and says the same thing.

I have correct connetion to the port 5666:

telnet 10.16.70.200 5666
Trying 10.16.70.200...
Connected to 10.16.70.200.

Try this where
$ARG1$ = 80
$ARG2$ = 90

It works perfectly in the service that I was testing:

OK: |'virtual'=0.00011TB;102.4;115.2;0;128 'virtual %'=0%;79;89;0;100

But, I try to copy it to other hosts and reponds the next:

Exception processing request: Request contained arguments (not currently allowed, check the allow arguments option).

I think it's because of the nsclient.ini, that in the first one there is something that in others is not

in the section You need then you will need to restart nsclient++
