Performance Monitoring

Risc91 · 07-11-2005, 02:40 PM

What is the best way to measure over all system performance for a given time interval. Say an hour or even a week? I currently have PDT running on a daily basis, but it only runs from 9am - 10am and it doesn't give me quite the information I'm looking for. (average disk I/O, cpu usage, paging, etc during the interval) Any suggestion are appreciated. TIA

Try the NMON tool. You can run it in batch mode to catch data on a given interval, for so many slices. Then you can use the NMON Analyzer to generate graphs from the data. It catches everthing you are looking for, along with some others you didn't mention.

+1 for nmon

Another options is nagios. It's an OSS project that is easily customised to add functionality and perform distributed monitoring...

@spiro : are you talking about that one ? http://www.nagios.org/ ?

Yep, that looks about right. I know it runs on many platforms and has a heap of plugins and scripts included with the base project. I've also discovered that there are other plugins floating around the web that are not part of the main project.

I wrote an RRD based, Hotsanic inspired, *NIX performance graphing system called MSR.
I spose I should open-source it... what do you think?

Yes, open-source is a great idea!
By the way, does your post mean that you want us to test your package and give us our opinion as standard users ?

Well, since I wrote it on the job, I think my employer's have the rights to it...
But I think I could convice them to let me post it.

I was just feeling it out, to see if there is a need for another performance charting app...

Nmon has some small problems and no support.
So, I would like to know, in case your system also has small problems, if you want us to tell you, and if you will be motivated to repair it. Else, if you prefer, we forget about all this.

Don't forget Cacti.

It's great!

ouch ! "Cacti requires MySQL, PHP, RRDTool, net-snmp, and a webserver that supports PHP "
ouch ! ouch ! ouch ! most of my Oracle systems don't have mysql, and probably none has PHP.
Most of us want a heavy-light program (let's say like vmstat + iostat) in order to gather some statistics without disturbing their user and without needing to install a lot of things.
For instance, nmon only wants you just to put a binary file (let's say nmon32) in a directory where you have read permission.
