graphical representation of crontab entries

[Michael Murphy_2]

Anyone have a shell/perl/tcl/other script/tool that would put out a graphical representation of crontab files - showing overlap and repitition of jobs etc...Thanks

Shalom,

sam may have something under routines tasks

However crontab -l and crontab -e are the way real systems administrators do this.

i should clarify - in this case i don't need a graphical interface - i want a graphical representation of what is in cron - so if i need to do system maintenance at a certain time and have 100 users kicking off 200 jobs i can see impact and slow periods. thanks

I understand what you are looking for, but I have never seen a tool for this. you could probably enter the info into project or something similar.

I can see how analyzing the crontab can tell
you when jobs will start, but if you wish to
know what's running when, wouldn't you need
to know when each job will end? I don't see
where crontab can help with that.

Murphy,

TWS (tivoli work scheduler) is one such tool for this.

You can see complete job scheduling details. But it is a commercial product.

At hp-ux level except crontab -l/e and cron logs we dont have any such facility.

Obviously cron(1m) has all this info. It needs to know when (and what) the next job starts.
As Steven said, it would only give start times, so it wouldn't need to be graphical, just a list of start times and who and what.

You may want to file an enhancement with the Response Center for an option for cron(1m) to dump this info.
