check_jenkins_job_extended plugin - JSON.pm query

Good morning,
I have recently downloaded and installed the check_jenkins_job_extended plugin.
When I attempt to run the following command:
Code: Select all
./check_jenkins_job_extended.pl -j MyJobName -l https://MyJenkinsServer
I get the following:
Code: Select all
Can't locate JSON.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at ./check_jenkins_job_extended.pl line 4.
BEGIN failed--compilation aborted at ./check_jenkins_job_extended.pl line 4.
Can anyone shed any light as to where I can find JSON.pm and how i would go about installing it, please?
Thanks in advance
Pete

"It is indeed", he typed, with an already sinking feeling...

Do you have perl-JSON installed? (case sensitive)

Thank you for your reply and apologies for the delay in replying myself!
I have now installed JSON and set up my service definition as follows:
Code: Select all
define service{
use generic-service
host_name MyJenkinsServer
service_description MyJenkinsJobName
check_interval 1
check_command cjj!MyJenkinsServerName!MyJenkinsJobName!0!0!0!0
}
and my command like this:
Code: Select all
define command{
command_name cjj
command_line $USER1$/check_jenkins_job_extended.pl $ARG1$ $ARG2$ $ARG3$ $ARG4$ $ARG5$ $ARG6$ $ARG7$ $ARG8$
}
but the web interface is currently returning "(No output returned from plugin) "
Even though the username and password fields are optional, I'm just wondering if I should add two parameter separators to indicate that I'm not including username or password, like this:
Code: Select all
check_command cjj!MyJenkinsServerName!MyJenkinsJobName!!!0!0!0!0
if I include my username and password like this:
Code: Select all
check_command cjj!MyJenkinsServerName!MyUserName!MyPassword!MyJenkinsJobName!0!0!0!0
the result is the same.
Note - I'm using the jenkins server hostname, rather than its URL, because when I use (for example) "
https://jenkinsbuildserver", I get:
Error: Could not find any host matching '
https://jenkinsbuildserver'
Any suggestions, good Nagios folk?
Thanks in advance.
Pete

Can you post the output of the check from the CLI? Sometimes this has a bit more information that we can use for helping to troubleshoot.
Code: Select all
./check_jenkins_job_extended.pl -j MyJobName -l https://MyJenkinsServer

When I do that, it just spits out an incorrect syntax message!
Code: Select all
Usage: check_jenkins_job url [user_name password] job_name concurrent_fails_threshold build_duration_threshold_seconds last_stable_build_threshold_seconds_warn last_stable_build_threshold_seconds_crit
I tried putting the jobname in double quotes, but with the same result.
Cheers

I also tried this:
Code: Select all
/usr/local/nagios/libexec > ./check_jenkins_job_extended.pl -l https://myjenkinsserver -j MyJobName 0 0 100 100
which returned:
Code: Select all
Basic authorization user name can't contain ':' at /usr/share/perl5/HTTP/Message.pm line 658
If I remove the double quotes around the jobname, I get the usage check message again.

Another variation:
Code: Select all
/usr/local/nagios/libexec > ./check_jenkins_job_extended.pl https://myjenkinsserver "my job name with spaces" 0 0 0 0
returns:
Code: Select all
UNKNOWN - Failed retrieving status for last build via API (API status line: )

The reason this won't work is because it's looking for things in a specific order, rather than a flag.
The plugin supports several options, which you can pass "0" to disable that particular threshold.
Usage: check_jenkins_job_extended url jobname concurrentFailsThreshold buildDurationThresholdMilliseconds lastStableBuildThresholdInMinutesWarn lastStableBuildThresholdInMinutesCrit
I don't have a Jenkins server to test with, but perhaps something along the lines of what you did second without the https may work? It seems to be parsing your job name, and the finishing variables without error. However, I don't see anything referencing if SSL is supported or not on GitHub.
Code: Select all
./check_jenkins_job_extended.pl http://myjenkinsserver "my job name with spaces" 0 0 0 0
