How often should you call your global cron script? There are several
things to think about:
-
How much fine control do you need? Running cron jobs once each hour is
usually enough for most tasks, but you might need to exercise finer
control for a few special tasks.
-
Are you going to run the entire cfengine configuration file
or a special light-weight file?
-
System latency. How long will it take to load, parse and run the
cfengine script?
Cfengine has an intelligent locking and timeout policy which should be
sufficient to handle hanging shell commands from previous crons so that
no overlap can take place, See section Spamming and security.
