Health and Event Monitoring

You can view switch-resident logs even if you have not set up your local syslog server or your local PC

is not in the switch's syslog server list. Due to memory constraints, these logs will wrap when they reach

a certain size. The switch syslog has two logs: an NVRAM log that holds a limited number of critical

and greater messages and a nonpersistent log that contains notice or greater severity messages. Hardware

messages are part of these logs.

Health and Event Monitoring

Fabric Manager works with the Cisco MDS 9000 Family switches to show the health and status of the

fabric and switches. Information about the fabric and its components is gathered from multiple sources,

including Online System Health Management, Call Home, system messages, and SNMP notifications.

This information is then made available from multiple menus on Fabric Manager or Device Manager.

The Fabric Manager Events tab, available from the topology window, displays the events Fabric Manager

received from sources within the fabric. These sources include SNMP events, RMON events, system

messages, and system health messages. The Events tab shows a table of events, including the event name,

the source and time of the event, a severity level, and a description of the event. The table is sortable by

any of these column headings.

The Fabric Manager web services client displays collections of information gathered by the Performance

Manager. This information includes events sent to the Fabric Manager Server from the fabric. To open

these reports, choose Performance Manager > Reports. This opens the web client in a web browser

and displays a summary of all fabrics monitored by the Fabric Manager Server. Choose a fabric and then

click the Events tab to see a summary or detailed report of the events that have occurred in the selected

fabric. The summary view shows how many switches, ISLs, hosts, or storage elements are down on the

fabric and how many warnings have been logged for that SAN entity. The detailed view shows a list of

all events that have been logged from the fabric and can be filtered by severity, time period, or type.

Device Manager displays the events when you choose Logs > Events. Device Manager can display the

current list of events or an older list of events that has been stored on the Fabric Manager host. The event

table shows details on each event, including time, source, severity, and a brief description of the event.
