My Icinga 1.14 web interface reports "Return code of 255 is out of bounds" despite the check returning an OK status. (The nrpe binary is not used to execute commands.)
/usr/lib64/nagios/plugins/check_snmp_load.pl '-H' '10.0.4.84' '-C' 'Y5Rap0I' '-2' '-T' 'netsl' '-w' '10,8,5' '-c' '15,12,10'
The above command renders Load : 0.00 0.00 0.00 : OK from the command line on the Icinga satellite but in the Icinga classic web interface I see Return code of 255 is out of bounds
