I wasn’t able to figure out how to implement this in LibreNMS, so we’ve been using this crude solution as a workaround.
I added an extra step to the nagios service check - it now uses imagemagick to create /opt/librenms/html/images/helpdesk_queue.png
The image can then be added to LibreNMS dashboard using the “External Images” widget (http://librenms.example.com/images/helpdesk_queue.png).

BEARER="blablabla"
# store the whole response with the status at the and
HTTP_RESPONSE=$(curl --url $URL --header "Authorization: Bearer $BEARER" --silent --write-out "HTTPSTATUS:%{http_code}")
# extract the body, then extract ticket_count value from the JSON
HTTP_BODY=$(echo $HTTP_RESPONSE | sed -e 's/HTTPSTATUS\:.*//g' | jq '.tickets_count')
# extract the status
HTTP_STATUS=$(echo $HTTP_RESPONSE | tr -d '\n' | sed -e 's/.*HTTPSTATUS://')
# if HTTP status is 200 OK, then return ticket_count
if [ $HTTP_STATUS -eq 200 ]; then
convert -size 550x275 -background none -fill white -gravity center -font Courier-Bold label:$HTTP_BODY /opt/librenms/html/images/helpdesk_queue.png
convert -size 550x275 -gravity center -font Courier-Bold label:$HTTP_BODY /opt/librenms/html/images/helpdesk_queue.svg
echo "$HTTP_BODY tickets in Helpdesk queue with no Owner | 'tickets'=$HTTP_BODY"
exit 0
fi
# if HTTP status is not 200 OK, exit with warning state
if [ ! $HTTP_STATUS -eq 200 ]; then
echo "Error [HTTP status: $HTTP_STATUS]"
exit 2
fi
Here’s how it looks:
