Parameter

Type of statistic

Description
Count of state failures Counter Number of state failures of this media channel during the summary period. This counts the number of times the Actual status of the ISUP Media Channel has moved out of the Active state when not requested.
Cumulative downtime Counter Cumulative downtime of this media channel during the summary period. This counts the number of milliseconds for which the media channel has not been active.
Number of circuits configured Gauge Number of circuits currently configured in this media channel. This counts the total number of circuits configured irrespective of their current status.
Number of circuits available Gauge Number of circuits currently available for use in this media channel. This counts the total number of circuits that are available for use by incoming and outgoing calls, including those that are currently in use. This count excludes inactive and blocked circuits.
Number of circuits in use Gauge Number of circuits currently in use in this media channel. This counts the total number of circuits that are being used for call traffic, or are in use by pending-active or pending-inactive calls, or are being tested.
Count of incoming call attempts Counter Number of incoming call attempts during the summary period. This counts the total number of ISUP IAM and CRM requests received for circuits in this media channel.
