Troubleshooting
This section explains how to view error and informational messages. In
addition, it discusses debugging techniques, as well as common errors
and how to fix them.
Error and informational messages
Messages are provided on stderr and through syslog.
•stderr
You can redirect stderr with the wlmoradc option
--stderrfile file
Alternatively, you can use the coll_stderr keyword in your WLM
configuration. This keyword allows you to capture stderr for all data
collectors in your configuration, not just wlmoradc. You can send
stderr to syslog or another file of your choosing.
•syslog
Typically, syslog is at /var/adm/syslog/syslog.log; if not, see
/etc/syslog.conf for a pointer to syslog on your system.
Also, WLM has a message log at:
/var/opt/wlm/msglog
Debugging suggestions
Following are some pointers when you are debugging:
1. Check syslog for indication of any problems.
2. Use the wlmoradc option --debug 1 to check that wlmoradc settings
match expected values.
