R: R: check_memory does not work properly

[Marco Borsani]

I use in many checks the “%” symbol without problem

I do not know for sure but I would suggest those '%'s are causing issues, try escaping them with a back slash. 
They might even need dubble escaping eg '\\\%' as they are being passed through levels of commands.
People tend to try and not pass-through special chars like that so it might be simpler to just edit your check script to just use plain values instead (./check_script -w 10 -c 5).

Posting your check configuration is really helpful in cases like this.  It’s almost impossible to give a good answer without knowing how you’ve set the check up.

Hi all

 

 

I am using a simple plug-in to check the nagios server memory.

 

When I run it like user Nagios, it works perfectly. I see this output:

OK - free memory is 40% which is within expected threshold| mem=40;10;5;0;100

 

When I run it with Nagios program I receive this notification:

 

…..

Command:         check_local_memory

State:                   WARNING

Message:            (null)

….

 

 

Any idea ?
