Quoting Adam Goryachev <user-eaec2ffb4cbc@xymon.invalid>:
You should have a xymonlaunch log file, does that report anything related to this task?
Nope. Nothing.
PS, on debian I always install the hobbit-plugins package, which includes a check for this already.
This didn't fix the problem for me, although it did at least produce a new 'libs' column with a warning about upgraded libs linked in running processes.
But, eventually I did fix the problem on my own. :-) I got the idea after reading this message:
http://lists.xymon.com/archive/2012-October/035800.html
Thus, the solution was to add an extra line to the end of /etc/xymon/tasks.cfg:
directory /etc/xymon/tasks.d
I would consider this omission a bug, as without this line everything placed in /etc/xymon/tasks.d is simply ignored.
Cheers,
Jaap
