How to get performance data out of a single check command (a script)  that returns only 1 value in nagios?

I have this probe.sh script, which checks for temperature of a probe, the result is a simple number, which is the temperature in Celsius. My goal is to make centreon draw graphs from this number, but it returns nothing but that number.  To draw graphs, nagios needs performance data, which involves a lot of other values to be returned from the script (command). So basically I'm asking for someone to write the rest of the script (which is a huge part really), a person who understands bash scripting and nagios. I'm not in a hurry, I just can't seem to do it.

Bellow is the command example, plus another command that returns pefdata (check_centreon_ping). If you need the contents of tp_read.pl, I'll add them, but they're irrelevant in my opinion, awk only filters the number after probe.sh, which is the probe identifier and which is the useless part of the output from that check. I can in desperation send the IP address and both scripts so someone could check if it's working as he tests it.

I know it's a serious task so I'm really grateful to anyone that decides to try this. Thank you!

You actually have two values, the time the check was done and the temperature.  What other value are you looking for?

I got it, it was just a matter of editing the output so nagios can understand it as performance data



declare -rx SCRIPT=${0##*/}
declare -rx CMD_AWK="/bin/awk"
declare  -rx CMD_CAT="/bin/cat"
declare  -rx CMD_FREE="/usr/bin/free"
declare  -rx CMD_GREP="/bin/grep"

TEMP=$(/usr/local/nagios/libexec/tp_read.pl d -f=10 -p=**.***.***.*** -a=$1|awk -F = '{print $2}')

if [ $TEMP -lt $CRITICAL ]; then
        echo "Temperature OK,Temperature Level: $TEMP|Temperature_level=$TEMP"
        exit $STATE_OK
        echo "High Temperature detected on Rack xx|$TEMP degrees"
        echo $STATE_CRITICAL
