[collectd] Having problems with notifications

[Andrés J. Díaz]

Hi János (et al)

I'm using collectd 4.7.0 with the proposed patch for plugin.c and exec
notification works for me. This is my piece of configuration file (a
dummy threshold for test):

<Threshold>
  <Plugin load>
    <Type load>
      WarningMax 0.1
    </Type>
  </Plugin>
</Threshold>

And the exec plugin section:

LoadPlugin exec
<Plugin exec>
#	Exec "user:group" "/path/to/exec"
	NotificationExec "ajdiaz" "/home/ajdiaz/test"
</Plugin>

The test file is a bash script owned by the user used in
NotificationExec with 755 perms, which only do a "cat >> /tmp/test"

Maybe you need to assign permissions to your .pl?, be carefull with
the owner of the file and the exec permissions on the directory. Try
to run manually the script: su -c /path/to/script nobody.

I hope to help you a bit :)

Regards,
  Andrés
