Hi people,


We are having certain problem with the CPU consumption in one of our machines a Netra 1405. We have an snmp GUI where we send the alarms for the CPU consumption. Every 30 minutes we get that the CPU is at about 80% of its usage. I have run the commands top and prstat -a but I have only seen that the CPU usage for the user to a maximum of 40% of its capacity. We get suddenly a kernel of up to 40% also.

CPU states: 32.2% idle, 30.6% user, 37.1% kernel, 0.1% iowait, 0.0% swap
Memory: 4096M real, 2219M free, 1150M swap in use, 10G swap free


   PID USERNAME THR PRI NICE  SIZE   RES STATE    TIME    CPU COMMAND
 26925 root      61  59  -20  137M   86M sleep   33.4H 30.75% java
  3262 oracle    11  59  -20  544M  507M sleep   46:34  0.51% oracle
   679 root       1  50    0 1096K  912K sleep  345:23  0.23% loms

Is there a better way to see the cpu consumption without the top or prstat -a commands? Why I get so high kernel usage? Is there a way to see this more deeply.

BR,

Joaquin
