Graphs for Capacity Planning not displaying

[louissiong]

Hi Nagios,

Lately, we configured a new service for our host. The service is meant to check how many
buffered messages are receiving at our server's end. However, this is not showing in our
'Capacity Planning' tab. Error message being 'There are no capacity planning graphs available for this host.'
Is there something we did wrong ?

Service Status Detail
Check BOLC Buffer Msg
ABLTMSGSVR01

Please advise. Thanks.

Louis

Do these services have regular performance graphs being generated (performance graph tab of the service status detail page)?

Hi Scott,
No it doesn't. Do we need to add anything to our Nagios scripts to produce the graphs for
CP ?

Yes, your script output must contain the performance data, this is what is used to create the capacity planning graphs as well.

Below is the instructions on format for performance data

Thanks Scott for your help. Managed to add some parameters to the script and churn out the graphs.
So is using the | (pipe) a standard way in Nagios to produce charts ?

PERFDATA="'BufferedMessages'=${count2};${ECOUNT};0;${ECOUNT}"
PERFDATATMP="${PERFDATA} ${PERFDATATMP}"

if [[ "$count2" -ge "$ECOUNT" ]]; then
echo "CRITICAL - Total number of actual Buffered Msgs [$count2] more than [$ECOUNT]. | $PERFDATATMP"
exit $STATE_CRITICAL
elif [[ "$count2" -le "$ECOUNT" ]]; then
echo "OK - Normal number of actual Buffered Msgs [$count2]. | $PERFDATATMP"
exit $STATE_OK
fi

Yes, it starts the performance data
