command; output is sorted by PRM groupname
choice=procs:process_groups
Lists the active workload groups using the HP-UX 'ps -efP'
command excluding PRM_SYS and OTHERS; output is sorted by
PRM groupname

DESCRIPTION
wlm_watch.cgi is a simple CGI script that lets a system administrator
monitor the workload groups and processes on a given server by having
Apache run wlminfo, prmlist, ps -ePR, prmmonitor, and other commands.
Only read-only commands are supported--the system administrator must
log into the system to make WLM or PRM changes.
Output
The output of the wlm_watch.cgi script is similar to the various WLM
and PRM commands that allow the user to list or monitor the workload
groups and their processes.
Errors
wlm_watch.cgi reports errors to the user's browser via the CGI::Carp
module.
EXAMPLES
Example 1
Run wlm_watch.cgi starting with the default menu:
http://myhost/cgi-bin/wlm_watch.cgi
Example 2
Call wlm_watch.cgi and immediately list the processes with workload
(PRM) group names:
http://myhost/cgi-bin/wlm_watch.cgi?choice=procs:process_list
Example 3
Call wlm_watch.cgi and immediately list the processes in the specific
'mygroup' workload group:
http://myhost/cgi-bin/wlm_watch.cgi?choice=procs:process_list&PRMGROUP=mygroup
RETURN VALUE
wlm_watch.cgi reports problems to the user's browser via the
CGI::Carp module.
LIMITATIONS
If showing workload groups, users, or process names is not acceptable
for your security situation, do not enable wlm_watch.cgi.
wlm_watch.cgi requires perl 5 and the CGI module. These are available
from various sources including http://www.hp.com/go/softwaredepot.
The CGI::Carp module is required if you want to display CGI errors in
the user's browser; otherwise, comment out the CGI::Carp line in the
wlm_watch.cgi file.
PATH DEPENDENCIES
To view the latest entries in the error_log and access_log,
wlm_watch.cgi must know where the logs files are. To be flexible,
wlm_watch.cgi attempts to locate the log files in potential apache
installation locations. First, wlm_watch.cgi checks the setting of
HPWS_APACHE_ROOT in /etc/rc.config.d/hpws_apacheconf if it exists. If
it does not, or there is no setting, /opt/hpws/apache/ is used. If
that does not exist, /opt/apache/ is used. If that does not exist
either, an error message is printed.
If you have used other paths for the the log files or you are not using
the default names access_log and error_log, you may need to modify your
copy of wlm_watch.cgi to view them. Be sure to modify the copy you
place in your cgi-bin directory, not the /opt/wlm/tool‐
kits/apache/bin/wlm_watch.cgi copy, as that copy will be overwritten
during any WLM upgrades.
