I think there is a problem with sending notification here, it seems like the icingaweb can’t send notification. If I try it here manually it does not send any notificition and still write “for this problem was not notification send”. I think somewhere are the notification disabled but I can’t find where?
Hi again.
icinga2 object list --type notification
Show your dummy-host1 with the host alert?
Greetings.

Did you execute the CLI command as root or icinga/nagios user (depending on your OS) ?
I am running the command
./mattermost.py --url https://mattermost.xxxxxxxxxx.com/hooks/xxxxxxxxxxxx --notificationtype CUSTOM --hostalias myexample.com
as root
in the folder
/usr/lib64/nagios/plugins/icinga2-mattermost
and my OS is linux
does the command work if it’s the icinga/nagios user? i’ve had problems with check scripts not being executable by nagios user in the past.
I can’t change the user with su icinga ? I tried but I get an error. This seems not the problem because on my second icinga istance it works fine with the root user. I can’t even send a notification manually when I am on the icinga webinterface. Or how do I run a command as a different user?
without knowing what the error is, here’s some things to look at:
sudo su - icinga
I checked
the script has ( -rwxr-xr-x / 0755 ) permission
and the folder has the same ( drwxr-xr-x )
like all other plugins.
su - icinga

This account is currently not available.
but this shouldnt be the problem because i have the same issue on my second icinga and there is the mattermost plugin working
the path in constants.conf is /usr/lib64/nagios/plugins which is the right one, alls plugins are stored here
regarding the notifcation.conf I dont know where I should put a path in here? and the command is also right
Hi again.
Since the “icinga” user does not have a login shell, you can not directly login.
As a workaround, you can use sudo here:
sudo -u icinga /path/to/the/script # Directly executing the script
# alternatively to get a shell: sudo -u icinga bash
# or whatever shell instead of bash (/bin/sh, ...)
Assuming that you are using RedHat/CentOS (because the user is “icinga”):
Did you check for SELinux related problems?
Greetings
I just checked I can run the command as icinga user manually and it works, I get a notification in my mattermost channel. I will check for SELinux problems and let you know what I find.
Can’t find anything in SELinux. What could be related to this problem.
Hi.
Maybe this helps:
link
SELinux was often mentioned in this forum, so maybe a search gives you further hints.
Greetings.
Okay Thank you. I checked that SELinux is disabled could this cause the Problem?
Hi again.
If SELinux is disabled, this does not cause the problem.
Sorry, I am out of ideas. At this point, it may be helpful to check on the Mattermost side (if possible) what is happening when you manually send a notification from icingaweb2.
Greetings.
okay thank you. I will check what I can do with mattermost. If I run the command the notificaiton arrives in mattermost. Its just confusing because I cant send a manual notification from icinga web interface.
okay I will but unfortunately there is no solution
