Subject: High System CPU Usage
All,
I have a cluster of 7 servers (ns client) running hava application and 1
NFS server. Sometime In the top output system CPU is 55%.
Could some give me a clues what might be causing system CPU to be that
high.
Tried these
Ps -eo pid,user,%cpu,args -sort %cpu the top list was java process and
mysql using 39% and 4% max.
Checked the output from sar -c, sar -b and at the peak time
04:10:02 PM proc/s
04:20:01 PM 40.02
04:30:01 PM 34.65
04:40:02 PM 35.74
04:50:01 PM 36.13
05:00:01 PM 40.61
05:10:01 PM 38.42
05:20:01 PM 32.75
Sar -P all
04:20:01 PM CPU %user %nice %system %iowait %idle
04:30:01 PM all 22.70 0.00 64.87 1.83 10.61
04:30:01 PM 0 24.14 0.00 63.88 1.69 10.29
04:30:01 PM 1 21.25 0.00 65.86 1.97 10.92
04:40:02 PM all 22.21 0.00 66.27 1.51 10.01
04:40:02 PM 0 23.53 0.00 65.23 1.53 9.71
04:40:02 PM 1 20.89 0.00 67.30 1.50 10.31
04:50:01 PM all 22.55 0.00 66.49 1.45 9.52
I can see the high usage by System CPU, but I want to find out what
might be causing this high so High System CPU. Any lead would be
appreciated.
Jai
