Hello,
Need your help. I'm new to Solaris administration. In our company, we use Sitescope to monitor the servers and network. Now it showing an alert on a Solaris server that its CPU utilization(6 CPUs) is 100%. Like this: "datamall CPU 100% avg, cpu1 100%, cpu2 100%, cpu3 100%, cpu4 100%, cpu5 100%, cpu6 100%".
To fix this, I get into the server and tried few commands I know to figure out the following:
1. How the CPU is utilized? Why it is overloaded?
2. Which process is taking the highest CPU usage?
3. What is the ideal load average a producation server should have?
4. Is there any zombie/hanging process which degards the CPU performance? Can I kill all those?
5. Is it okay if CPU running 100% like this or it may crash?
6. Finally the basic things: What is the speed of processor? Is there physically 6 CPU's or it a virtual?
Commands I tried are given below. Is there any better way to figure out the CPU utilization?
