Check Output Data Format

[nicholashadaway]

I have a check which returns numbers but I would like to format the number to an integer.

I'm not sure what I need to pass to the command to get the right formatting for integer output:
$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v COUNTER -l "\\Server\\Errors Logon","Since last reboot","logon errors"

Is there documentation somewhere that shows the string formatting options? (%.2f etc)
Can somebody guide me to what I need to change in my check to get the correct formatting of the data output so I get integer output?

If this won't meet your needs you'll need to use another plugin as it requires a floating point per the help section:

Code: Select all

/usr/local/nagios/libexec/check_nt -H X.X.X.X -s 'secret' -p 12489 -v COUNTER -l "\\Server\\Errors Logon"

COUNTER =
Check any performance counter of Windows NT/2000.
Request a -l parameters with the following syntax:
-l "\\<performance object>\\counter","<description>
The <description> parameter is optional and is given to a printf
output command which requires a float parameter.
If <description> does not include "%%", it is used as a label.
Some examples:
"Paging file usage is %%.2f %%%%"
"%%.f %%%% paging file used."

So really it's a printf formatting thing:

Are you just trying to remove the perdata float value (.000000) or what specifically are you trying to do?

That clarifies it nicely. It is printf formatting ...

So, in order to get an integer I use "%d"

Thank you for your guidance.
