check_citrix help ..

[Stanley Hopcroft]

Dear Folks,

Darren Hobbs plea for help with check_citrix has this answer (posted Thu

'
No output! (see base/checks.c) is what Nagios sets the plugin output to 
when it reads _nothing_ from the file handle connected to the plugin 
process stdout.
 
In other words, the plugin has written nothing to stdout because it 
abended or failed to handle what it received.
 
You can shed some light on the matter by, when you ask for help
 
1 reporting OS (name and version)
 
2 reporting plugin version
 
as the footer of each mail in the archives or on the lists asks for
 
(> Nagios-users mailing list
> Nagios-users at lists.sourceforge.net
> https://lists.sourceforge.net/lists/listinfo/nagios-users
> ::: Please include Nagios version, plugin version (-v) and OS when

3 If you understand and can live with the consequences of this
modification to your setup, the results when you
 
3.1 rename your check_citrix plugin to something like
check_citrix_WRAPPED
 
3.2 create a script called check_citrix containing something like
 
#!/bin/sh

# start_plugin_wrapper
 
exec > /suitable/path/BAD_PLUGIN_whining 2>&1
 
exec <path_to_nagios>/libexec/check_citrix_WRAPPED $@

# end_plugin_wrapper


# BAD_PLUGIN_whining is the name of a file in a path writable by
# Nag (eg /tmp). It will contain any output - including compiler 
# warnings to stdout.

Warning ! I haven't tried this with my Nag setup. It will probably 
behave no worse than what you have at the moment, but YMMV.

Change file modes and install in <path_to_nagios>/libexec/

Check_citrix was conceived for pre Citrix Metaframe /XP. There is some
doubt as to whether the ICA browse service is required for Metaframe
/XP.


Yours sincerely.

BALLAD OF A THIN MAN
(Words and Music by Bob Dylan)

You walk into the room
With your pencil in your hand
You see somebody naked
And you say, "Who is that man?"
You try so hard
But you don't understand
Just what you'll say
When you get home

Because something is happening here
But you don't know what it is
Do you, Mister Jones?

You raise up your head
And you ask, "Is this where it is?"
And somebody points to you and says
"It's his"
And you say, "What's mine?"
And somebody else says, "Where what is?"
And you say, "Oh my God
Am I here all alone?"

Because something is happening here
But you don't know what it is
Do you, Mister Jones?
