CPU Monitoring

Hello All, I'm looking for best practices with regard to CPU monitoring. I have systems where the CPU is overloaded, and we really can't do much about it. What do most folks do with the CPU monitor with regard to showing RED all the time? Thanks.James

Set the thresholds high enough where they aren't red anymore. If you have no control over CPU Utilization on those systems there isn't much more that you can do.

While others may disagree, I think that Hobbit should be configured for what you expect to be normal situations and notify you when it goes above those situations. If you think ServerA's Load can be 2.00 without an issue, go ahead and configure it that way. Yellow - 2.00, Red 2.25 (or whatever you consider appropriate). --Pat

Hello All,
I'm looking for best practices with regard to CPU monitoring.
I have systems where the CPU is overloaded, and we really
can't do much about it. What do most folks do with the CPU
monitor with regard to showing RED all the time?
Thanks...James

Hi Rich, But eventually you are going to want to improve resources. At least when management asks for new equipment requests, etc... You would not be able to track it if you disable the red. Is there a way to keep the background green, but maybe use another color to keep track of improvement areas. Just brainstorming a bit. Thanks...James

If by track you mean the graph, it is still populated with the high load values, so that can be used to show management that over time this machine has had excessive utilization. You may be able to find a thresshold where the machine bounces between green, yellow and red during the day. Be aware though that each time it goes between colors that a histlog entry is made (which may require more disk space, depending upon how often it bounces and how long you let it bounce).

I don't have a different suggestion to those already made, but I do have a related question for everybody: would there be any value in having a CPU minimum load setting that would trigger a red flag?? I'm thinking that in a normally heavily loaded system, a sudden drop in cpu activity could indicate a problem. Or is there already a way to invert the condition?? I don't have a set of manual pages handy to check right now... Ralph Mitchell
