The Failure Distribution report provides an analysis of failed sessions.

Filters

Filters provide a way for you to return a more finely-targeted set of data or to view the returned data in different ways. For example, the Failed Distribution Report enables you to filter on such things as the activity type (peer-to-peer session or conferencing session) or by the diagnostic ID that accompanied each failed session.

The following table lists the filters that you can use with the Failure Distribution Report.

Pool

Fully qualified domain name (FQDN) of the Registrar pool or Edge Server. You can either select an individual pool or click [All] to view data for all the pools. This drop-down list is automatically populated for you based on the records in the database.

Activity type

Type of activity to filter on. Select one of the following:

  • [All]

  • Peer-to-peer

  • Conference

Session category

Indicates whether the activity in question succeeded or failed. Select one of the following:

  • [All]

  • Success

  • Expected failure

  • Unexpected failure

An "expected failure" is a failure that is expected to happen. For example, if a user has set his or her status to Do Not Disturb you would expect any call to that user to fail. An "unexpected failure" is a failure that occurs in what would appear to be an otherwise healthy system. For example, a call should not be terminated if the caller is placed on hold. If that occurs, that would be flagged as an unexpected failure.

Diagnostic ID

Unique identifier (in the form of an ms-diagnostics header) attached to a SIP message that often provides information useful in troubleshooting errors. Diagnostics headers are optional (it is possible to have SIP sessions that do not include these headers), and diagnostic IDs are reported only for sessions that experienced problems of some kind.

Metrics for Top Diagnostic Reasons

The following table lists the information provided in the Failure Distribution Report based on the most frequently reported diagnostic ID.
