Icinga2-agent-kickstart script not detecting installed icinga version on client

Hi All,

I am trying to complete host registration in Icinga Director setup. But icinga kickstart agent script is not detecting installed Icinga2 version.

[root@cent7-clients ~]# ./icinga2-agent-kickstart.bash
INFO: This should be a RedHat system
check: icinga2 installed - ERROR: You need to install icinga2!

[root@cent7-clients ~]# icinga2 --version |grep “version: 2.11.0-1”
icinga2 - The Icinga 2 network monitoring daemon (version: 2.11.0-1)

Please let me know how to fix above issue.



there is a bug in the kickstart script which doesn’t properly detect the version. https://github.com/Icinga/icingaweb2-module-director/issues/1944

You can adjust the regex with this small change:

michi@mbpmif ~/dev/icinga/icingaweb2-module-director (master *=) $ git diff

Thanks Michael for your help. Today I will try this above changes.

I’ve send a PR for the Director, this will be included in 1.7 as well.

Hi Michael,

I have made the above changes in ‘icinga2-agent-kickstart.bash’, but now I am getting below errors. Is there any other changes needed ?

No idea, sorry. I hate bash programming and try to avoid it whenever possible. The regex was just simple to test. Might be a syntax problem with bash-ism, still qualifies for an upstream bug on GitHub.

Thanks Michael for all your help.

I have temporary fixed the issue by adding another grep filter (grep daemon) to show only icinga version. previously It was capturing two values one Icinga version and second Linux kernel version.

Below is the modification, which worked for me.

“$ICINGA2_BIN” --version 2>/dev/null | grep daemon| grep -oP ‘version: [rv]?\K\d+.\d+.\d+[^)]*’
