High CPU usage.

[pra$h Online!!!! !!]

Dear all


I am using nagios 2.7 and monitoring 674 host and 6995 service checking .

Last few days i found that my web page is slow.
When i check my server  procs i found that some time apche (status.cgi ) is
taking 70 to 90% CPU usage and too many nagios instance also running some
time.

  PID USER      PR  NI %CPU    TIME+  %MEM  VIRT  RES  SHR S COMMAND
7569 apache    25   0   60   0:02.99  0.3 12108 9988  488 R status.cgi
14055 apache    25   0   47   0:02.94  0.3 12240   9m  488 R status.cgi
13879 apache    25   0   46   0:04.05  0.3 12636  10m  488 R status.cgi
14033 apache    25   0   23   0:02.91  0.3 12240 9.9m  488 R status.cgi

  PID USER      PR  NI %CPU    TIME+  %MEM  VIRT  RES  SHR S COMMAND
19394 apache    25   0   72   0:03.53  0.3 12372  10m  488 R status.cgi

19796 apache    18   0    4   0:00.13  0.2 11956 8008 4620 R status.cgi

I restated my apche server .but the issue not resolved .


No changes made to the configuration file.

Nagios perfomance is good
  Check Execution Time:   0.04 sec 23.30 sec 0.268 sec Check Latency: 100.55
sec 117.00 sec 109.142 sec Percent State Change: 0.00% 42.63% 0.04%


Can anybody help me on this.

Thank in Advance
