execute a script when alert conditions are met

Help

Problem/Question

I need to execute a certain script and/or a binary when certain alerts are triggered.
can’t make it work. probably missing something simple

relevant config file:
/etc/netdata/health_alarm_notify.conf

[cpu_usage_exceeded]
# Define the condition (CPU usage exceeding 50% for 5 minutes)
alarm = on
trigger = $cpu_user > 50
duration = 5m

command = /scripts/alertme.sh

Environment/Browser/Agent’s version etc

Debian 11
latest netdata

What I expected to happen

the script is executed

what I may be doing wrong? how to debug this?
Is there somewhere a minimal example I can follow?

In terms of alert configurations the place to set the custom script is the exec attribute - Configure alerts | Learn Netdata

The default SCRIPT is Netdata’s alarm-notify.sh , which supports all the notifications methods Netdata supports, including custom hooks.

Probably looking to alarm-notify.sh could be a good example to follow.

I am aware of /usr/libexec/netdata/plugins.d/alarm-notify.sh.
it gets executed, as we are receiving the configured Slack notifications.
We want to run our own script instead.
According to the doc Configure alerts | Learn Netdata
it is just a matter to pointing the exec parameter to it. That does not work for us.
not sure how to debug it.
there are few log files in /var/log/netdata but neither is helpful.
maybe there is some global option to increase verbosity of the logs so we see what netdata does not like about our script?
I double checked the permissions. they are set exactly to what alarm-notify.sh has

ok, that goes beyond my knowledge on this domain so I’ve raised this internally to see if someone can help.
