We have been missing a very small feature and no clue if it is small to implement. We have some programs running which we would love to get an alert from if it already has been running x time. See it as a warning before the actual timeout runs out. It is very similar to the uptime testing for programs and the config could be similar to:
check program ls with path '/bin/ls' timeout 100 seconds every '0 0 * * *' if running > 50 seconds then alert
Thanks in advance!
