Real CPU use?

[ittec]

Hi

these question is the tipically question that everybody ask someday in his live. How can we know the real value of Linux load? In Windows we have a Task Manager and graphic interface to see the % of cpu load. But in Linux only have cpu load that is more hard to know whats going on.

So using Zabbix Software, How you check yours CPU loads servers? Here explain more or less the sense of my question.

So I will thank you if someone want to share his experiences.

Thanks!

I use the kernel's performance counters under /proc/stat.

you can use cpu.util on linux. The tricky part is if you want a graph like Task Manager you really need to graph 100 - idle% but as of now its impossible to do in ZABBIX because items and graphs can't do math. I just monitor idle% and graph it and switch my brain when viewing to remember 98% constant "usage" is a good thing.

I use the % idle value, too. It's simply the best, even for triggers.

with Zabbix

Thanks to all

interesting anwers but, How is the simple or easiest way to do this with Zabbix? Or better, with normal items and triggers by default of zabbix, What is the best combination of them to imagine the real situation of cpuy?

Im using now "Processor Load" that is a good reference but not to do a completely image of cpu stat.

thanks

I recommend two things.

1. Petition for someone to fix the unix agents so we can get total cpu utilization
2. in the meantime, you can create an item such as the following to get cpu usage:
system.run[sar -P ALL 1 2 | grep 'Average.*all' | awk -F" " '{ print 100.0-$NF }']

Thanks, now I have some graphs with Cpu.load and cpu.iddle time.

hello

i have a plobem, i'm not know How breakdown the CPU? i need know what consumer process my CPU

[ittec]

Shell

I don't know if zabbix support something as this but if you had acces by ssh to your host, you would run "top" command and see the values of any process. Sorry, I can't help you more

Bye

[israel dominguez]

sorry my server in monitoring is windows

[ittec]

ups

This is another question my friend. Perhaps someone here can help you with Windows monitoring through Zabbix, but I say the same. Connect to your host by Terminal Server and list process with "Task Manager". List the process by cpu %.

In windows you can use performance monitor to monitor the cpu utilization of individual processes.

[israel dominguez]

ok Tanks, i always working in servers unix, in windows how minitor the cpu utilization of individual processes. i have make a .bat or .exe????

[israel dominguez]

Good

with proc_info monitor process of CPU
