check_mem not work correctly

[baber]

dear all

Hi

on my linux server i use check_mem.pl plugin for chk memory plugin status

Code: Select all

command[check_mem]=/usr/local/nagios/libexec/check_mem.pl  -f -w 15 -c 10

and add this to service :

Code: Select all

define service{
        use                                       generic-service
        host_name                           ntmbsrv
        service_description             Memory
        check_command                  check_nrpe!check_mem
}

my problem is when my memory usage is high it will be appeaer critical but after 2 days server status is now ok and memory status is now decrease and is ok but my memory status is still appear critical and don't change to ok

what is problem ?

Please post your nrpe.cfg

Please post your nrpe.cfg

This line is on remote host nrpe.cfg


command[check_mem]=/usr/local/nagios/libexec/check_mem.pl -f -w 15 -c 10

Is that literally all that is in your nrpe.cfg? Seeing the settings will help us understand any issues you are having. If you are concerned about security, you can PM.

Did you post the right service definition? It says check_nrpe!check_mem

i have added this to command.cfg file on nagios server

Code: Select all

define command{
        command_name    check_mem
        command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -C '/usr/local/nagios/libexec/check_mem.pl -f -w 15 -c 10' -E
}

and added this on remote host for service

Code: Select all

define service{
        use                                      Mobile-service
        host_name                          npmbsrv3
        service_description            Memory
        check_command                  check_mem
}

now after 3 days status of memory on nagios show critical although my memory status is very low and attached pic from top on server why critical warning from monitoring not remove now ?

You only have 150MB of memory free, I believe Nagios is reporting correctly. Take a look at the free -m command which may be a bit easier to visualize.
