Re: check program entry that runs only once using the every [cron] line

[Marc Rossi]

Right now I run the program with cron and have that send success/failure email, which I could certainly offload to monit via some mechanism (such as log / drop file as you suggest) to allow monit to detect success / failure.

What I am trying to accomplish is not having crontab entries spread across all of my machines.  Right now I am able to start/stop programs in monit remotely from a single centralized crontab (hitting remote monit http port via python script) and as the number of machines grows it is nice to have only a single crontab to manage.  In addition, I can fire off that remote script at any time via the monit web interface or from m/monit which isn't possible if it is scheduled in cron.

I'd even be open to adding a mode to monit called "batch" (in addition to "active", "passive" and "manual") that would allow a job to be run once when start is clicked.

Hello, I saw your post and wanted to ask...

Just curious what you are trying to monitor for. If you can run the program with cron, why not just have the script log an entry or create a drop file, then have monit monitor the file and give alert based on that?

I guess I don't understand what end result you are achieving here.
