Monitoring events Web Tools displays fabric-wide and switch-wide events. Event information includes sortable fields for the following: • Switch name • Message number • Time stamp • Indication of whether the event is from a logical switch or a chassis • The number of successive events of the same kind • Severity level • Unique message identifier (in the form moduleID-messageType) • Detailed error message for root cause analysis There are four message severity levels: Critical, Error, Warning, and Info. Table 4 lists the event message severity levels displayed on the Switch Events tab and in the Fabric Events window, and explains what qualifies event messages to be certain levels. On the Switch Events tab and in the Fabric Events window, you can click the Filter button to launch the Filter Events dialog box. The Filter Events dialog box allows you to define which events should be displayed on the Switch Events tab or in the Fabric Events window. For more information on filtering events, see "Filtering Fabric and Switch Events" on page 51. TABLE 4 Event Severity Levels Icon and Level Description Critical Critical-level messages indicate that the software has detected serious problems that will eventually cause a partial or complete failure of a subsystem if not corrected immediately; for example, a power supply failure or rise in temperature must receive immediate attention. Error Error-level messages represent an error condition that does not impact overall system functionality significantly. For example, error-level messages might indicate timeouts on certain operations, failures of certain operations after retries, invalid parameters, or failure to perform a requested operation. 48 Web Tools Administrator's Guide Publication Number: 53-1000435-01
