These allow you to send the time your task took, along with the boundary time that you consider acceptable.
If the task took too long, then IsItWorking will alert you.
#!/bin/sh start=`date +%s` /Users/rob/Documents/Development/Rails/IsItWorking/test/scripts/slow_script.sh end=`date +%s` runtime=$((end-start)) curl -d "t=$runtime&b=5" https://api.IsItWorking.info/c/CHECKIN_IDENTIFIER
In this example, if slow_script.sh takes more than 5 seconds, you'll get an alert.
