Events & Alarms

UFM allows you to identify any problem, including ports and device connectivity, using events and alarms. Problems can be detected both before running applications and during standard operation.

Events trigger alarms (except for "normal" events. i.e., Info events) when they exceed a predefined threshold. Events and alarms can be configured under Events Policy tab under Settings window. For more information, refer to Events Policy Tab.

Users can enable the events persistency mechanism from the gv.cfg. This allows the user to see the events in the case of restarting the UFM or in HA mode.

The persistency is deactivated by default and can be enabled by the following controlled parameters in the config file:

• max_restored_events = 50 # – will determine the number of events to restore

• events_persistency_enabled = true # – will set to true for the feature to work

The Device Status Events tab displays topology change events related to devices in a table. it will support the following event types:

• None is Up/Down

• Switch is Up/Down

• Director Switch is Up/Down

Filters are be provided to allow events filtering by the desired time interval with a length limit.

The Link Status Events tab displays topology change events related to links in a table. It supports the following event type:

• Link is Up/Down

  

Filters are provided to allow filtering by the desired time interval in a time range.
