Nagios Support Forum

Hi all! Does anybody use subj?
I get NULL everytime from that plugin. Here are my configs

define command{.
command_name<-->check_mysql_query
command_line<-->$USER1$/check_mysql_query -H a.b.c.d -P 3306 -d database -u user -p password -q 'SELECT COUNT(`post_name`) FROM wp_posts;' -w $ARG1$ -c $ARG2$
}.

define service{
<------>use<---><------><------>generic-service
<------>host_name<-----><------>server
<------>service_description<--->costs
<------>check_command<-><------>check_mysql_query!10!20
<------>}


When I run command from cmd everything is ok and I get
usr/lib64/nagios/plugins/check_mysql_query H a.b.c.d -P 3306 -d database -u user -p password -q 'SELECT COUNT(`post_name`) FROM wp_posts;' -w 1 -c 2
QUERY CRITICAL: 'SELECT COUNT(`post_name`) FROM wp_posts;' returned 36,000000

Where is the problem?

I need to ask the obvious question here, but are you actually putting <-----> in your configs?

Not. I use mc, and <--> appear when I insert code there.

The first troubleshooting step will be to try to run the same command from the cli while logged on as the nagios user.

Please try that and report back the results.

-bash-4.1$ /usr/lib64/nagios/plugins/check_mysql_query -H a.b.c.d -P 3306 -d database -u user -p password -q 'SELECT COUNT(`post_name`) FROM wp_posts;' -w 10 -c 20
QUERY CRITICAL: 'SELECT COUNT(`post_name`) FROM wp_posts;' returned 36,000000

When it run from the cli while logged as the nagios user everything looks fine with result.

By chance do you have any special characters in your password?

I had, but now changed the password, and nothing happens. In cli `ok`, nagios has 'null'

What is the output of a grep '$USER1' /usr/local/nagios/etc/resource.cfg command?

$USER1$=/usr/lib64/nagios/plugins

Can you run a 'pre flight check?' /usr/lib64/nagios/bin/nagios -v /usr/lib64/nagios/etc/nagios.cfg

If that doesn't work, my paths may be slightly off. I am not used to that directory structure. How did you install Nagios? What OS is it running on?
