[mrtg] Re: mrtg performance

[Schuyler Bishop]

I wonder if this is related to my other issue - getting "artifacts" for
spikes in my interfaces... it only seems to happen for a single poll, but I
get "spikes" that are 70-80% of theoretical max.  It's really annoying!
Granted, I'm polling over the internet...

 While we're on this subject, I'd like to throw a query out.

 I'm running mrtg & rrdtool.  I'm querying about 80 pieces of
equipment right now.  I'm running mrtg in daemon mode and forking 80
times.

 My problem is that if I lose a group of equipment, those queries will
wait and hang waiting for a response.  In the meantime, 5 minutes have
gone by and time to query the equipment again, but its still waiting on
the others.  After several rounds of querying, I have a ton of waiting
processes and it is not not querying my other equipment.  So essentially
I'm not getting data for anything.

 Anybody else having this kind of problem?  Suggestions?  Thoughts?
Ideas?
