Introduction
Mediation Server is a necessary component for implementing Enterprise Voice and dial-in conferencing. It translates signaling and, in some configurations, media between your internal Lync Server infrastructure and a public switched telephone network (PSTN) gateway, IP-PBX, or a Session Initiation Protocol (SIP) trunk. Mediation Server role be collocated with the Front End Server role in a similar manner as the Web and A/V conferencing roles. Monitors current audio channels with PSM quality reporting, load call failure index, etc.

Collected Metrics
| Metric Name | Display Name | Description |
|---|---|---|
| NumberofOutboundCalls | NumberofOutboundCalls | This component monitor returns the total number of active calls going through the Mediation Server. |
| NumberofOutboundActiveMediaBypassCalls | NumberofOutboundActiveMediaBypassCalls | This component monitor returns the total number of active calls going through Mediation Server that are in Media Bypass mode. Calls using Media Bypass use significantly fewer Mediation Server resources because the media is not flowing through the Mediation. |
| NumberofInboundCalls | NumberofInboundCalls | This component monitor returns the number of inbound calls in progress. |
| NumberofInboundActiveMediaBypassCalls | NumberofInboundActiveMediaBypassCalls | This component monitor returns the number of media bypass calls in progress. |
| Media_Relay_MediaConnectivityCheckFailure | Media_Relay_MediaConnectivityCheckFailure | This component monitor returns the number of calls where media connectivity between the Mediation Server and the remote endpoints could not be established. It indicates that the Mediation Server cannot reach the Media Relay. |
| Mediation_Server_LoadCallFailureIndex | Mediation_Server_LoadCallFailureIndex | This component monitor returns the scaled index between zero and 100 that is related to all call failures due to Global Health Index as a heavy load. This indicates that the Mediation Server is receiving calls more than it can handle. |
| Mediation_Server_CurrentAudioChannelsWithPSMQualityReporting | Mediation_Server_CurrentAudioChannelsWithPSMQualityReporting | This component monitor returns the total number of active channels that are having Phase Shift Modulation (PSM) quality reported. Calculating PSM quality has a processing overhead so this should be taken into account when measuring performance. |
| Mediation_Server_TotalFailedCallsCausedByUnexpectedInteractionFromTheProxy | Mediation_Server_TotalFailedCallsCausedByUnexpectedInteractionFromTheProxy | This component monitor returns the number of calls that failed because of an unexpected response from the Front End Server. The returned value should be as low as possible. |
| Mediation_Server_TotalFailedCallsCausedByUnexpectedInteractionFromAGateway | Mediation_Server_TotalFailedCallsCausedByUnexpectedInteractionFromAGateway | This component monitor returns the number of calls that failed because of an unexpected response from a gateway peer. The returned value should be as low as possible. |
