as a general best practice, prefer to use absolute path.
this way, you avoid path related issues due to the launch context (see
> In order to check if it is called, the script writes in /tmp/alarm.txt

> Upsmon runing in debug using command line as root "/usr/sbin/upsmon -D" =>
> /tmp/alarm.txt is written, alarms are sent to my alarm management framework.
are you cleaning the testbed before each tests (ie "rm -f /tmp/alarm.txt"),
just to be sure?

the user context you launched the command from... but more probably here,
the way you retrieve data from upsAlarmManager to write it to the file and
To be able to confirm, or at least troubleshoot this issue, I'd need, if
possible, to have a look at your script.
If that pose a problem to do it publicly, don't hesitate to send it to my @
