Troubleshooting Solaris platforms

The following procedures describe how to troubleshoot Solaris platform workstation
issues.
Procedure 7-1 Problem: Slow processing on a Solaris workstation
and CPU peaks
The workstation is taking too long to perform a task. Check the CPU status to ensure that
one process is not using most of the CPU cycles. Then use the mpstat and ps commands
to further review CPU usage data.
You can also perform other procedures:

•
If you are you performing a large listing operation using the 5620 SAM client GUI
or OSS, check the LAN throughput using the netstat command, as described in
Procedure 8-1.
•
Check for excess disk usage using the vmstat command, as described in
Procedure 7-3.
Obtain the UNIX utility top and install the utility on the Solaris workstation.
Open a command or shell tool.
Change to the 5620 SAM install directory by typing:
cd /install directory ↵
where install directory is the installation directory of the 5620 SAM software
Run the top command to check for processes that are consuming CPU cycles:
i To list the top CPU processes using top, type:
top ↵
To list the top CPU processes using the UNIX utility prstat, type:
prstat ↵
Depending on your system configuration, approximately the top 20 processes
are displayed. The displays are similar for top and prstat.
ii Review the output. The following is sample top output.
Last PID: 4099; load averages: 0.00, 0.01, 0.01
85 processes: 66 sleeping, 19 running, 1 on CPU
Cpu state: 0.0% idle, 99.8% user, 0.2% kernel, 0.0% oiwait,
