Summary: check_citrix issues
Initial Comment:
I ran into these issues using the check_citrix plugin, so
I'll share them here in the hopes that they will allow the
continued development of the plugin and of the
excellent Nagios package.
Issue 1) Lots of applications to look for
If one has a large number of apps to look for, one should
split the seach into multiple services and have each
service look for a subset. The danger is that the buffer
used to hold all the search string will overflow, and
Nagios 1.2 will seg fault. One can alternatively try
increasing the buffer size in the plugin, and use the -L
option, but even so I still hit the seg fault after a couple
of dozen apps.
Issue 2) Lots of apps in the list
The plugin returns the application list on errors. If this
list exceeds the default nagios return buffer, the plugin
will behave strangely. I had it returning an OK status in
nagios (green) and showing the "Failed: " string in
status information. I assume this is due to a lack of
buffer error checking in Nagios (can that be fixed?). I
simply removed the print statements that show the list
on errors, and while it is less informative, it still tells me
when an application is missing from the list.
