[mrtg] Re: AIX specs

[Derek Winkler]

This wasn't on AIX but I found this worked really well for me...

Create 5 configs which have nothing but includes of other configs.

Load should be spread evenly across the 5 configs.

The startup script then starts the configs one minute apart from eachother.

To do this I had a perl script which would count the number of targets in a
config following includes.

I also had a startup script that you could supply the config to be started
and the delay until it was started.

This keeps cpu usage steady instead of spiky.

But then again I only have 125 targets on a dual processor machine with 2GB
of memory.

May not be an original idea but worth re-stating.

Good luck.

Subject: [mrtg] AIX specs


I know there isn't an exact science for sizing a server for MRTG, but
wondered if anyone can give some feedback on what they are using as it
pertains to the following.
We are moving MRTG from Win2k to Aix 4.3.  MRTG has outgrown the Win2k
box, and the AIX box we're moving MRTG won't be able to handle it
either.  We currently run approx. 500 config files every 5 minutes,
where one config file is retrieving one piece of data on one box (i.e.,
one config file retrieves BW util for all interfaces on routerA, one
retrieves crc errors for all interfaces on routerA, one retrieves BW
util for all interfaces on routerB, etc.)  Having not run MRTG in an AIX
environment, I would like to find out what others are using as a loose
guide.  If anyone running MRTG on AIX can share information on their
hardware specs, how their config files are set up to run and how the box
is holding up, it would be greatly appreciated.  

Thanks in Advance
