No output returned from plugin status

[elinagios]

Do you mean somewhere in nagios logs or in that script specified logs?

[scottwilkerson]

your script is logging items here

Code: Select all

LOG_FILE="/home/nagios/monitoring.$(date "+%Y%m%d").log"

[elinagios]

So i changed the state file content from OK -> test-error and in the logfile:
2020-06-15 11:00:31 - returning status code 0, message:OK
2020-06-15 11:02:29 - returning status code 0, message:OK
2020-06-15 11:04:28 - returning status code 0, message:OK
2020-06-15 11:04:55 - returning status code 2, message: test-error

Was one of these from when you did not get the correct output from nagios?

[elinagios]

Yes, nagios reckognizes it's an critical event, changes status from OK to critical but status information is "no output returned from plugin"

[scottwilkerson]

This really is a puzzle, I see no reason for this.

What do you get if you set it to OK and run if from the CLI

Code: Select all

[nagios@mynagios ~]$ /usr/local/nagios/libexec/check_cmd.sh someip

[elinagios]

From cli i get Server is OK. Same i get from nagios web interface, status information field. OK status information is always shows correctly.

Sorry I misunderstood, what if you make it go CRITICAL
then run

Code: Select all

/usr/local/nagios/libexec/check_cmd.sh someip
echo $?

[elinagios]

[nagios@nagiosserver ~]$ /usr/local/nagios/libexec/check_cmd.sh serverip
test-error
[nagios@nagiosserver ~]$ echo $?
2

I labbed this up with the same scripts and it's working properly.

Please send me a copy of your profile, you can download it from Admin > System Profile > Download Profile button. I want to see if there is something else going on.
