Alert filtering
You can filter the alerts that are displayed in the Alerts tab according to the severity of the alert,
whether the alert was acknowledged or resolved, and the source ID of the alert.
Filtering alerts
1. Select a fabric, switch, or the entire SAN in the View panel, as described in “Alert monitoring”
on page 93.
You cannot filter the switch group alerts.
2. Click the Alerts tab in the Information panel.
User authentication fails Generated when a change to the user role prevents the user from being authenticated
on the switch. The last occurrence time of the alert is updated every time the condition
is detected, such as when the user logs in to the switch or manually refreshes the
status information, or when Fabric Manager automatically polls the switch.
The alert is resolved when the user credentials are changed and authentication is
successful.
Performance Monitoring Two types of fabric-level alerts are generated by Performance Monitoring: data
collection (through the five-minute thread), and end-to-end monitor validation (through
the 24-hour thread).
The alerts are resolved (by the five-minute and one-hour threads, respectively) when
the error condition that raised the alert is rectified. The alert is logged the first time
the error is encountered and remains until the data is recaptured successfully or you
turn Performance Monitoring off.
The following scenarios generate an alert:
• Resource limit exceeded
• Advanced Performance Monitoring license removed or otherwise unavailable on
a switch where end-to-end monitors needs to be created
• Combination of resource limit and license missing
• Authentication failure through API
• API reports a fabric access exception, causing an alert to be logged with the API
error code and error message (if available)
• Database exceptions
These alerts are at the fabric level.
A third type of alert can be created by Performance Monitoring: port data collection.
You must enable port data collection as described in “Enabling port data collection”
on page 114. The following port data collection events generate port data alerts:
• Port Rx%
• Port Tx%
• Tx link resets
• Rx link resets
• CRC counts
• Signal losses
• Link failures
• Sequence errors
• Invalid transmissions
• Sync losses
These alerts are at the switch level.
