Troubleshooting

Troubleshooting on UNIX

The machine that contains the SCI may be down or the network is unreachable. Also, the intended machine may be mistyped or unknown to the name server. Try the following steps:

1.Verify network connectivity. Run /usr/sbin/ping <machine>. Reference the ping(1M)man page for more information.

2.Verify the name server configuration for your network. For example, if you are using DNS or /etc/hosts, run

/usr/sbin/nslookup <machine>. Reference the nslookup(1) man page for more information.

This new threshold put the set of thresholds out of order. At least one threshold won’t be violated until a higher priority threshold is violated. You may wish to edit it later to change its priority.

Threshold rules are misconfigured.

Ensure that the lower priority threshold rule is violated after the higher priority rule.

Error Logging and Tracing

The WebQos components use the following log files to record WebQoS related activity. You can use these files to monitor the WebQoS server and help with troubleshooting. The files are:

/var/opt/webqos/logs/qoslog

/var/opt/webqos/logs/qoslog.child

/var/opt/webqos/logs/qostrace

/var/opt/webqos/logs/qostrace.child

/var/opt/webqos/measures

/var/opt/webqos/logs/scalog

/var/opt/webqos/logs/scatrace

/var/opt/webqos/logs/scilog

/var/opt/webqos/logs/scitrace

/var/opt/webqos/logs/scolog

/var/opt/webqos/logs/scotrace
