Joe ‘Zonker’ Brockmeier looks at whenjobs


I’ve been using whenjobs quite a lot (probably I’m the single most extensive user). Some things I like:

  • The ability to list jobs and ‘tail’ the output of jobs as they are running. A big improvement over cron where jobs are effectively opaque and undebuggable.
  • Restarting jobs because of temporary failures.

And some things I don’t like:

  • You can’t set multiple variables atomically.
  • It’s hard to predict the effect of setting a variable, ie. which jobs will run after you execute a particular whenjobs --set command.
  • It probably would be better if whenjobs could work across mulitple hosts, with each host having a shared view of the current variable state.

(The first two of these are fairly simple to fix)
