Using HP WebQoS

Troubleshooting

Logging

Error messages are logged in the /var/opt/webqos/logs/qoslog and /var/opt/webqos/logs/acclog ﬁles. You can set the level of logging (number and types of messages) by setting the parameters in the ﬁle /etc/opt/webqos/qos.conf. For information on how to set the parameters, see “Modifying WebQoS Global Conﬁguration” on page 27. More messages will be logged by changing the levels. See “Changing Logging and Tracing Levels” on page 118 for more information.

Tracing

The /var/opt/webqos/logs/qostrace and /var/opt/webqos/logs/acctrace ﬁles are for use by HP Support.

Measurement Logging

If you have set the LogOn parameter in the /etc/opt/webqos/qos.conf ﬁle to on, WebQoS creates a new measurement log ﬁle daily for each WebQoS site and places them in /var/opt/webqos/measures. The measurement log ﬁle name is the site name that was entered in the management user interface followed by the date. For information on how to set the logging level, see “Modifying WebQoS Global Conﬁguration” on page 27.

Statistics Logging

If you have enabled Service and Site Statistics Logging in the management user interface, WebQoS generates statistics and creates ﬁles in /var/opt/webqos/logs.

The statistics log ﬁle names are the site name or service name that you entered in the management user interface followed by the date. For information on how to enable Statistics Logging, and for a description of which statistics are generated, see “Adding a Service” on page 45for Service Statistics Logging, and “Enabling Site Statistics Logging” on page 82 for Service Statistics Logging.

Changing Logging and Tracing Levels

The product ships with default levels. For logging, the default level is informative messages. Tracing is turned off. We recommend that you run the product with these levels. Turning on more detailed levels will quickly ﬁll up the logﬁles. The levels are set in the /etc/opt/webqos/qos.conf ﬁle. There is more information on the
