Troubleshooting with Logs
Cisco SAN-OS generates many types of system messages on the switch and sends them to a syslog
server. These messages can be viewed using Fabric Manager or the CLI to determine what events may
have led up to the current problem condition you are facing.
This section contains the following topics:
•
Viewing Logs with Fabric Manager, page 1-13

logged events:
