pmp-check-mysql-status -l $USER3$ -p $USER4$ ......

Hello there,

I have been trying to setup the nagios plugins to my monitoring server and I defined the following command on the remote server’s nrpe_local.cfg.

pmp-check-mysql-status -l $USER3$ -p $USER4$ -H $HOSTADDRESS$ -x Threads_connected -o / -y max_connections -T pct -w 80 -c 95

(Of course, I replaced the username, password and hostaddress with all the appropriate info.)

and I got the following output on the monitoring server. [TABLE]
[TR]
[TD=“class: dataVal”]awk: line 8: syntax error at or near )
awk: line 13: syntax error at or near if
awk: line 24: syntax error at or near exit
CRIT Threads_connected / max_connections (pct) = 1.986755[/TD]
[/TR]
[TR]
[TD=“class: dataVar”]Performance Data:[/TD]
[TD=“class: dataVal”]Threads_connected/max_connections=1.986755;80;95$;0;100[/TD]
[/TR]
[/TABLE]

can someone tell me how to fix it ?

Sorry, I am new to nagios.

Thanks for looking at my post and for your help in advance.

Please run the command manually using sh -x pmp-check-mysql-status … and show the excerpt of the output with awk errors.
Also what’s the OS?

Hello Weber,

Thanks for your post. The following is excerpt of the output. Also, the OS is Ubuntu 12.04.

desmondkan, can you run the full command with “sh -x” to get the error with “awk” command, e.g.
sh -x /usr/lib64/nagios/plugins/pmp-check-mysql-status -l user -p pass -H somehost -x Threads_connected -o / -y max_connections -T pct -w 80 -c 95

Sure … the following is the output.

Unfortunately, there are no errors in the output like you posted initially:
awk: line 8: syntax error at or near )
awk: line 13: syntax error at or near if
awk: line 24: syntax error at or near exit

Please re-run the similar sh -x command for debugging purpose once you get the errors with awk to track it down.

Weber,

That’s true. I don’t see the errors anymore if I ran the command manually but I am still getting the same error message If I put the same command into the nrpe_local.cfg (which is on the remote server).

I guess my syntax is NOT right in the cfg file or should I put this command into the monitoring server instead of the remote server?

could you tell me where I should define the command if I should put this command into the monitoring server?

Thanks for your help.
I am really appreciated.

The command like this “pmp-check-mysql-status -l $USER3$ -p $USER4$ -H $HOSTADDRESS$ -x Threads_connected -o / -y max_connections -T pct -w 80 -c 95” should go to the nagios config and nagios replaces those vars with the respective values.
