Top Failures Report

 

Topic Last Modified: 2011-02-03

The Top Failures report provides a list of the most frequent failures and their trends over time.

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 Top Failures Report enables you to filter the returned data based on such things as the activity type (peer-to-peer session or conferencing session) or by the SIP response code that accompanied the failed session. You can also choose how data should be grouped. In this case, usages are grouped by hour, day, week, or month.

The following table lists the filters that you can use with the Top Failures Report.

Type of activity. Select one of the following:

  • [All]

  • Peer-to-peer

  • Conference

At this time the only option available is [All].

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.

Category

Type of failure experienced. Select one of the following:

  • Both expected and unexpected 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.

Response code

SIP response code sent when the conference failed. Enter the entire response code For example:

400

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.

The following table lists the information provided in the Top Failures Report.
