[Nagios-users] Escaping Exclamation Points

Discussion:

Hello all,

Never posted here before, but it's been helpful to follow along with the various threads.

My issue is with checking NT services with exclamation points in their names. The following check command is sent to NSClient++:

check_nt_service!'Act! Scheduler'

and fails with a No Output! error in Nagios. I've tried \!, $!, double quotes, and to no avail.

Has anybody had success escaping an exclamation point when it's part of a service name sent to NSClient++?

Thanks in advance,

Chris

Hi Chris,

Have you tried double exclamation marks (!!)? If you want to escape $ it's done by $$ so maybe ! works the same way?

That sentence is almost unreadable due to punctuation but I hope you get the drift :-)

Remove ' or complete, for example
check_nt_service!Act! Scheduler or check_nt_service!'Act'! 'Scheduler'
Put here commands.cfg for check_nt_service

Unquoting it all gives me "Act: Unknown" instead of no response at all.

check_nt_service is:

define command{
command_name check_nt_service
command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 1248 -v SERVICESTATE -l $ARG1$
}

Thanks,

Chris

Problem resolved.

What I just ended up doing is creating a new command, check_act_scheduler identical to the check_nt_service command definition, and hard-coding 'Act! Scheduler' instead of $ARG1$. That took care of it.

I actually define the following Service configs to help deal with these
issues.

define command{

command_name check_nt_l

command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 1248 -v $ARG1$ -l "$ARG2$"

}

THen I use the following for the service definition.

check_nt_l!SERVICESTATE !Act\! Scheduler

I have not tested in NSClinet++, but have tested this configuration through
NC_NEt.

The primary problem was the ! in the service definition was Tokenizing the
parameter into differerent $ARGX$

All nagios plugins would have this same issue,Another common issue is the
$ where using $$ usually works.

New feature in 3.x --
http://nagios.sourceforge.net/docs/3_0/whatsnew.html
Escaped command arguments - You can now pass bang (!) characters in
your command arguments by escaping them with a backslash (\). If you
need to include backslashes in your command arguments, they should
also be escaped with a backslash.
