Custom Status Field strings and warning levels

[Izz Abdullah]

Hi all,

I would like to format the data returned from check commands in the status information field of the GUI.  For example, I would like to add text after the check command has returned only an integer value, or another example I have brought up previously, divide the result by say 1024 to view in KB (when returned in bytes) or MB (when returned in KB).  Any ideas?

I am using COUNTERs with check_nt (NSClient++) on RHEL 4 server running Nagios v3.0.1 with the latest plugins.

I have tried different combinations of the description field:
check_nt!COUNTER!-l "\\Memory\\Available MBytes","%%.f Physical Memory Available"
check_nt!COUNTER!-l "\\Memory\\Available MBytes","%%.2f Physical Memory Available"
check_nt!COUNTER!-l "\\Memory\\Available MBytes","%%.f %%%% Physical Memory Available"

All of these return at least one percent sign, and no value, such as:
%f Physical Memory Available

If I leave out the description field (check_nt!COUNTER!-l "\\Memory\\Available MBytes") then I get a correct integer value.

I would like the GUI to show (assuming a server / machine with 2gb memory and has available 1348MB:
"1348 available out of 2048"
or maybe even use a percentage of available as is in the built-in Memory Usage command, but
this looks at the page file, not physical memory.

On another note, since I am using a large amount of COUNTER defs to check Windows servers, can someone tell me how to set the warning and critical in the check_nt!COUNTER! command?  Say the available memory in the above example reaches below 500, I want a warning, and below 250 a critical.

Thanks in advance,
Izz
