Adjusting Alarm Thresholds
When the VB7880 channels and streams have been defined using default thresholds, the result can
be a number of more or less permanent alarms, some of which may not be relevant under the current
circumstances. In order for the user to get rid of unwanted alarms, the extractor provides alarm filtering
functionality in the form of alarm thresholds and alarm on/off selection.
Multicasts
Creating a new threshold template is done either by copying an existing one and altering the copy, or by
creating a new threshold template from scratch. The Ethernet thresholds are defined in the
Multicasts
— Ethernet thresh.
View. These thresholds are associated with streams in the
Multicasts — Streams
view. In addition to the miscellaneous thresholds, that affect only the streams with which they are
associated, the
Alarm — Alarm setup
view allows the user to enable and disable alarms on an overall
basis. It is also possible to define the alarm severity levels for different alarms in this view.
OTT
When a OTT channel is defined the default OTT threshold template is assigned to it. To change threshold
values create one or more new templates in the
OTT — Thresholds
view and assign them to OTT
channels in the
OTT — Channels — Edit
view.
