check_async is supposed to wrap an NRPE command and overrides the return code.
|

|

Usage: check_async --max-age=1d --name=check_name
|

or check_async --name=check_name
|
||||
|
||||
Options
|
||||
-m, --max-age max age of the "check file" ;
|
||||
can be "1d" for 1 day, "5m" for 5 minutes…
|
||||
or more complex expressions like "1w2d10m42s"
|
||||
-n, --name check name
|
||||
-h, --help print this message and exit
|
||||
-V, --version print version and exit
