[Nagiosplug-devel] check_procs problem

[Dave Viner]

how about these args for ps on freebsd:

/bin/ps waxo 'state uid ppid ucomm command'

the ucomm column according to the man page should print 
	"ucomm      name to be used for accounting"
which on my system is the command name without any path.
but command will still print out the full executable and arguments.

no - wanted "egrep -i" to see the header for the ps output.

If the above succeeds, the follwoing are set:
PS_RAW_COMMAND,"$PATH_TO_PS waxo 'state uid ppid command'"
PS_COMMAND,"$PATH_TO_PS waxco 'state uid ppid command command'"
PS_FORMAT,"%s %d %d %s %n"


Perhaps as Ton Voon stated - the second command needs to be changed to 
PS_COMMAND,"$PATH_TO_PS waxo 'state uid ppid command'"

command without -c will list both executable and args, but with -c only 
lists the command.
