Recently, a friend introduced me to healthchecks.io, a service for monitoring cron jobs.
A week or so ago, I configured several of my cron jobs to be monitored through this system, and it has already helped me: yesterday I received a notification that an rsync job did not run, and the reason for that failure turned out to be a filesystem that was unintentionally unmounted. I remounted the filesystem, and today I received a notification that the rsync job finished as expected. What a great service.
I am a system engineer in the Raleigh, NC area. My main interests are Unix, VMware, and networking. More about me, and how I got started.
