monitor PMON and listner

[cyient]

Hi,

We are looking to monitor PMON and listner in a Oracle server but unable to find the plugins.

Any idea about this ?

Hi i have written a bash script for monitoring the process which we are looking for but i get timed out error when calling the script from nagios server through nrpe but when i call other check_load or check_user commands i get the output easily.

Is there any modification to be done to the script, i have attached the script for reference.

Please suggest on this.

Can you post the service and command definition for the check, as well as the nrpe.cfg command from the remote host?

I'm executing the service through nrpe from nagios server as below

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 192.168.3.4 -c check_ora

in nrpe.cfg file on remote server command definition is as below

Code: Select all

command[check_ora]=/usr/local/nagios/libexec/check_pid -p ora_pmon_pcontrolqq

You may have permission problems or timeout issues.
Run the following on the remote system:

Code: Select all

su - nagios -c "time /usr/local/nagios/libexec/check_pid -p ora_pmon_pcontrolqq"

Here is the output of the command

Code: Select all

 su - nagios -c "time /usr/local/nagios/libexec/check_pid -p ora_pmon_pcontrolqq"
Password:
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
ora_pmon_pcontrolqq is running.

While I am not sure which one it is, as they are all valid, or so it seems one of your greps is failing. This may or may not cause the issue you are seeing, but should be resolved regardless. The standard error output may be causing the delay or pseudo delay that makes check_nrpe timeout. You might also try adding a -t 30 flag to extend the timeout even though it doesn't appear to need it.

I have tried using the timeout arg but it did not work.

Code: Select all

$ /usr/local/nagios/libexec/check_nrpe -H 192.168.3.4 -c check_ora -t 30
CHECK_NRPE: Socket timeout after 30 seconds.

Have you verified that you can make an actual connection via the NRPE socket to that host? What is the output of:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 192.168.3.4
