Hi,

If a system is running slow then how to identify the root cause ?

Thanks,

Hi Raj

what kind of slowness you found?

Check your disk
#sar -d 5 5

check CPU usage

#sar -u 5 5

check iostat

check memory usage


#swapinfo -tm

if you have glance plus

go there and investigate where is the problem.

Dear Raj

This is mainly due to the performance issue
so recommend thing is u have to monitor systematically check health of the system with different tools
like iostat,vmstat,sar
swapinfo -tam , top
please all these commands and check out put
and if u have dought regarding output
pls send us

thanks and regards

Hi,
You can use "kmeminfo" script which will tell in details of per user basis cpu and memory usages.

Hi,

Is there any monitoring tool.

If glance is Installed use #gpm command.
or #glance .

Also check sar -u 1 10

hi,

are you observing any particular symptons either at the application level or Operating system levels?


What type of application are your running?

Is the kernel properly tuned?


revert!
