Enhancements To The Scripts Listing Processes and Memory Usage of PeopleSoft Application Server and Process Scheduler

In the post released in February I introduced a script that is able to list all processes of a Peoplesoft app server/process scheduler as well as each process' memory usage information.

I have enhanced this script with the following new features:

- For Peoplesoft App Server & Process Scheduler:

= When -m is specified, the script will print CPU usage percentage aside from memory usage.

= For app server, ports opened by JSL/JSH/WSL/WSH will be printed.

See above example.

= When -r is specified, the script will print the summary memory and CPU usage of processes of all app servers/process schedulers running on the server. This is useful when you need to monitor server's performance. Actually Oracle recommends that the total resident memory for the entire PS Processes not exceed 70 percent of the total real memory available on the server.

- For Peoplesoft Web Server: the script now can print some configuration information and running information (memory and CPU usage) of a web domain.

$ ~/bin/pl -w webdomain
DOMAIN:        webdomain
TYPE:          Single Server
WEBSITES:      server1, server2
HEAP SIZE:     -Xms512m -Xmx512m -XX:MaxPermSize=256m
SERVER:        PIA
 HTTP:        8080
 HTTPS:       8843 enabled
 PID:         19098
 RESOURCES:   VSIZE=893.8m RSS=700.4m CPU=0.2%

The help message:

Usage 1: list process info for a app server and/or a prcs server
   pl [-f] -c|p [-m -h] [-s] 

Options:
   -f force execution even appserv domain doesn't exsit
   -c print processes of application server
   -p print processes of process scheduler
   -m print memory usage (virtual memory and RSS) and CPU usage(%)
   -h print memory usage in human readable format
   -s print summary and statistical info

Usage 2: calculate RAM/CPU usage of all app/prcs processes
   pl -r

Usage 3: list setting and running info from a web domain (Weblogic only)
   pl -w 

Currently only Solaris version of the script is available. You can get it from here.

Update on 13-Oct-2009: Some bug fixes. pl -w produces more information.
