mailcow provides the ability to check for updates using its own update script.
|
|
|
|
If you want to check for mailcow updates using checkmk, you can create an executable file in the `local` directory of the checkmk agent (typically `/usr/lib/check_mk_agent/local/`) with the name `mailcow_update` and the following content:
|
|
|
|
````
|
|
#!/bin/bash
|
|
cd /opt/mailcow-dockerized/ && ./update.sh -c >/dev/null
|
|
status=$?
|
|
if [ $status -eq 3 ]; then
|
|
echo "0 \"mailcow_update\" mailcow_update=0;1;;0;1 No updates available."
|
|
elif [ $status -eq 0 ]; then
|
|
echo "1 \"mailcow_update\" mailcow_update=1;1;;0;1 Updated code is available.\nThe changes can be found here: https://github.com/mailcow/mailcow-dockerized/commits/master"
|
|
else
|
|
echo "3 \"mailcow_update\" - Unknown output from update script ..."
|
|
fi
|
|
exit
|
|
````
|
|
|
|
If the mailcow installation directory is not `/opt/`, adjust this in the 2nd line.
|
|
|
|
After that re-inventory the services for your mailcow host in checmk and a new check named `mailcow_update` should be selectable.
|
|
|
|
This will run the `mailcow_update` everytime checkmk agent is checked, you can cache the result by placing the script in a subfolder named the number of seconds you wish to cache it. \
|
|
`/usr/lib/check_mk_agent/local/3600/` will cache the response for an 3600 seconds (1 hour).

## Screenshots
|
|

|
### No updates available
|
|
|
|
If there are no updates available, `OK` is displayed.
|
|
|
|
|
|
|
|
### New updates available
|
|
|
|
If updates are available, `WARN` is displayed.
|
|
|
|
|
|
|
|
If `CRIT` is desired instead, replace the 7th line with the following:
|
|
|
|
````
|
|
echo "2 \"mailcow_update\" mailcow_update=1;1;;0;1 Updated code is available.\nThe changes can be found here: https://github.com/mailcow/mailcow-dockerized/commits/master"
|
|
````
