[mrtg] Re: mrtg showing very high cpu usage cause of otherapprunning

[Tim Sheets]

One thing to be aware of when switching to daemon....  Any time you
update an MRTG .cfg file, you will have to stop and restart the MRTG
process.  With straight cron, the changes will be picked up on the next
polling cycle.  As James points out, the .cfg file isn't read every 5
minutes..

Also, I would look at combining the other scripts you are running into a
single "master" script that calls the others.  As you have seen, it is
loading perl and that script a bunch of times every 5 minutes.  By
combining into a single script that processes each config in succession,
you will at least spread them out, and possibly save yourself quite a
bit of overhead, depending on how you implement.

Have fun!
