| Parameter | Description |
---|
| number | A sequence number which identifies the interval for which the set of statistics is required. The interval N identifies the recently completed interval, Interval N is identifed by the last sequence value and N-( number of intervals) is the earlest completed interval. |
| name | The name of this trunk group. |
| intervalValid | The member indicating the validity of the interval. |
| time | The system up time when the interval statistic is collected. |
| inUsage | The usage in the inbound direction for this trunk group for the specified interval. Usage is defined as the time media bandwidth is activated to the time it is deactivated. |
| outUsage | The usage in the outbound direction for this trunk group for the specified interval. Usage is defined as the time media bandwidth is activated to the time it is deactivated. |
| inCalls | The number of completed inbound calls on this trunk group for the specified interval. |
| outCalls | The number of completed outbound calls on this trunk group for the specified interval. |
| inCallAttempts | The number of inbound call attempts on this trunk group for the specified interval. |
| outCallAttempts | The number of outbound call attempts on this trunk group for the specified interval. |
| maxCompletedCalls | Displayed as maxActiveCalls. The high water mark of total number of active calls in both the inbound and outbound directions on the trunk group for the specified interval. This statistic accounts for calls that are setting up, stable, or tearing down. |
| callSetupTime | The cumulative duration (in 100th's of a seconds) from an INVITE sent to receiving the first backward 18x response on the egress leg. This value is nearly identical on the ingress counter with any latency due to the time spent for the SBC to send out the received 18x. If no 18x response is present, the callSetupTime is the final 200 response (cumulative count). |
| callSetups | The total number of calls setup but not necessarily completed in the inbound and outbound directions for this trunk group for the specified interval. This object can be used as the denominator for calculating average call setup time. |
| routingAttempts | The number of routing attempts for this trunk group for the specified interval. |
| inBwUsage | The sum of BW usage (expected data rate in bits per second multiplied by call duration in seconds) for every inbound call associated with this trunk group for the specified interval. |
| outBwUsage | The sum of BW usage (expected data rate in bits per second multiplied by call duration in seconds) for every outbound call associated with this trunk group for the specified interval. |
| maxActiveBwUsage | The high water mark of BW usage in either direction associated with this trunk group for the specified interval. |
| callsWithPktOutage | The number of calls with a maximum packet outage whose duration exceeds the configured minimum for this trunk group for the specified interval. |
| callsWithPktOutageAtEnd | The number of calls whose maximum packet outage occurs at the end of the call for this trunk group for the specified interval. This is an indication that the call may have been terminated the because of poor quality. |
| totalPktOutage | The summation of packet outage durations (in milliseconds) whose duration exceeds the configured minimum which is reported during the specified performance interval. The average packet outage duration can be calculated by dividing this field by the number of calls reporting packet outages. |
| maxPktOutage | The single longest maximum reported packet outage duration (in milliseconds) experienced during the specified performance interval for this trunk group. |
| podEvents | The number of Packet Outage Detection (POD) Events detected for this peeer group for the specified interval. A POD event occurs when a configurable number of calls experience a packet outage with duration exceeding a programmable threshold. |
| playoutBufferGood | Number of calls with all sub-intervals reporting GOOD playout buffer quality for this trunk group for the specified interval. |
| playoutBufferAcceptable | Number of calls with all sub-intervals reporting ACCEPTABLE or better playout buffer quality for this trunk group for the specified interval. |
| playoutBufferPoor | Number of calls with all sub-intervals reporting POOR or better playout buffer quality for this trunk group for the specified interval. |
| playoutBufferUnacceptable | Number of calls with at least one sub-interval reporting UNACCEPTABLE playout buffer quality for this trunk group for the specified interval. |
| sipRegAttempts | The current number of SIP registration attempts on a trunk group for the specified interval. |
| sipRegCompletions | The current number of SIP registrations that have successfully completed on a trunk group for the specified interval. |
| callsWithPsxDips | The number of calls that made a PSX Dip in the interval |
| totalPsxDips | The number of PSX Dips in the interval |
| activeRegs | The Interval number of active registrations on this trunk group. |
| maxActiveRegs | The Interval number of maximum active registrations on this trunk group (this is the high-watermark achieved on this trunk group). |
| activeSubs | The current number of active subscriptions on this trunk group. |
| maxActiveSubs | The current number of maximum active subscriptions on this trunk group (this is the high-watermark achieved on this TG). |
| peakCallRate | Peak call arrival rate within a specified interval on this trunk group |
| totalOnGoingCalls | Total On Going Calls (Non-Stable + Stable) on this trunk group |
| totalStableCalls | Total Stable Calls on this trunk group |
| totalCallUpdates | Total Call Updates on this trunk group |
| totalEmergencyStableCalls | Total Emergency Stable Calls on this trunk group |
| totalEmergencyOnGoingCalls | Total Emergency Calls Stable + Non-Stable on this trunk group |
| inRetargetCalls | The number of incoming calls that are retargeted by Load Balancing Service for the specified interval |
| inRetargetRegs | The number of incoming registrations that are retargeted by Load Balancing Service for the specified interval |
| outRetargetCalls | The number of outgoing calls that are retargeted by Load Balancing Service for the specified interval |
| outRetargetRegs | The number of outgoing registrations that are retargeted by Load Balancing Service for the specified interval |
