i'm having some performance problem on one of my linux machines and i hope someone will be able to help me analyzing the problem.
machine info:
Linux fedora, cpu x 4 cores of 1.6Ghz, 8G memory, 8G swap.
i've enabled sar on my machine and created a graph using ksar utility for the last week.
the sar -A command actually monitored everything on my machine.
now, i'm trying to understand what was the problem
my problem was that on 2 days at that week my application hanges and we had to restart the machine in order to solve this.
now, i'm trying to understand its its i/o problem due which related to my disk, or perhaps memory problem.
the problem occured at 15:00PM on one of the days i've monitored. i will write down the resluts:
i hope it was clear
i can see there is not enough memory cause he used almost all the memory, and the runq-sz is high so a lot of process running/waiting to run i think, so perhaps it might indicate the problem?
please help...

hi,
can any one tell me, is there is any way i can check the performance of my solaris 8 os on an Ent 3500. Other than top to check for the top most processes, how to make the calculations with vmstat, iostat, mpstat and nfsstat. Or is there any other tools that i can use?
cheers. (3 Replies)
Hi All
I am looking for a script that would collect statistics in a summarised format.
CPU, Memory,Swap, Wait queue, Run queue and disk activity.
Something that would allow me to profile the environment based on a 1 line output that I could run every 15 min.
Thx
