Shell monitor script how to

HOW TO create a shell script monitor

• STDOUT:

Output written to stdout by the shell script will be interpreted as performance monitor data and will have an rrd generated for it. the format of the output should be data name 0|data value 0;...;data name N|data value N If your output includes a line that starts with "title: foo", then foo will be set as the rrd title (note this is only used when the rrd is created)

• STDERR:

data written to stderr (ie. echo "blah" >&2) will be interpreted as monitor output and will be saved as the monitor_status

• Exit value:

The status of the monitor is determined by its exit value

< 0 = critical

0 = ok

> 0 = warn

• Environment variables:

PANOPTES_MONITOR_ADDR the ip address of the device being monitored will be set here PANOPTES_MONITOR_PARAM if a parameter is defined for the script, it will be set here in addition to being passed on the command line
