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 Edge 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 |
|---|---|---|
| SIP_503ResponseRate | SIP_503ResponseRate | This component monitor returns the rate of 503 responses generated by the server, per second. The 503 code corresponds to the server being unavailable. On a healthy server, you should not receive this code at a steady rate. |
| SIP_504ResponseRate | SIP_504ResponseRate | This component monitor returns the rate of 504 responses generated by the server, per second. A few 504 responses to clients (for clients disconnecting abruptly) is to be expected, but this counter mainly indicates connectivity issues with other servers. |
| SIP_ActiveConnections | SIP_ActiveConnections | This component monitor returns the number of established connections that are currently active. A connection is considered established when peer credentials are verified (e.g. via MTLS), or the peer receives a 2xx response. |
| SIP_ActiveTLSConnections | SIP_ActiveTLSConnections | This component monitor returns the number of established TLS connections that are currently active. A TLS connection is considered established when the peer certificate, and possibly the host name, are verified for a trust relationship. |
| SIP_AverageOutgoingQueueDelay | SIP_AverageOutgoingQueueDelay | This component monitor returns the average time, in seconds, that messages have been delayed in outgoing queues. |
| SIP_IncomingRequestsRate | SIP_IncomingRequestsRate | This component monitor returns the rate of received requests, per second. You will need to baseline this counter by testing and monitoring the user load. |
| SIP_IncomingMessageRate | SIP_IncomingMessageRate | This component monitor returns the rate of received messages, per second. You will need to baseline this counter by testing and monitoring the user load. |
| SIP_AverageIncomingMessageProcessingTime | SIP_AverageIncomingMessageProcessingTime | The average time (in seconds) it takes to process an incoming message. This could indicate if this server is too busy and is unable to process user requests in timely fashion. This might be a temporary condition. |
| SIP_AverageHoldingTimeForIncomingMessage | SIP_AverageHoldingTimeForIncomingMessage | This component monitor returns the average time that the server held the incoming messages currently being processed. |
| SIP_ExternalMessagesWithInternallySupportedDomain | SIP_ExternalMessagesWithInternallySupportedDomain | This component monitor returns the persecond rate of messages received at the external edge with an internally supported domain. |
| SIP_ExternalMessagesWithAllowedPartnerDomain | SIP_ExternalMessagesWithAllowedPartnerDomain | This component monitor returns the persecond rate of messages received at the external edge with an allowed partner server domain. |
| SIP_ExternalMessagesWithConfiguredAllowedDomain | SIP_ExternalMessagesWithConfiguredAllowedDomain | This component monitor returns the persecond rate of messages received at the external edge with a configured allowed domain. |
| AV_Authentication_Edge_BadRequestsReceivedPerSecond | AV_Authentication_Edge_BadRequestsReceivedPerSecond | The number of bad requests received/sec. This error occurs when an unexpectedly high rate of invalid requests is received by the A/V Authentication Service. This could be the result of an attempt to misuse the A/V Authentication Service. |
| SIP_ConnectionsRefusedDueToServerOverload | SIP_ConnectionsRefusedDueToServerOverload | The persecond rate of the connections that were refused with Service Unavailable response because the server was overloaded. |
| WebConferencingEdge_CurrentNumberOfActiveConnectionsToWebConferencingServer | WebConferencingEdge_CurrentNumberOfActiveConnectionsToWebConferencingServer | The total number of server connections that are currently active. Expected number of connections to each Web Conferencing Server is 4. If there are no connections currently active to Web Conferencing Server, the reason could be a incorrect configuration. |
| AudioVideoEdge_UDPActiveRelayAuthenticatedSessions | AudioVideoEdge_UDPActiveRelayAuthenticatedSessions | This component monitor returns the number of active relay sessions over UDP. |
| AudioVideoEdge_UDPActiveRelaySessionsWithAllocatedPort | AudioVideoEdge_UDPActiveRelaySessionsWithAllocatedPort | This component monitor returns the number of active relay sessions with a UDP port allocation. |
| AudioVideoEdge_UDPActiveRelayDataSessions | AudioVideoEdge_UDPActiveRelayDataSessions | This component monitor returns the number of active relay data sessions over UDP. |
| AudioVideoEdge_UDPPortsInAllocatedPool | AudioVideoEdge_UDPPortsInAllocatedPool | This component monitor returns the number of UDP ports available in the Allocated Port Pool. This monitor should be more than zero. If it reaches zero there is a resource issue. |
| AudioVideoEdge_UDPAllocateRequestRate | AudioVideoEdge_UDPAllocateRequestRate | This component monitor returns the persecond rate of Allocate Requests over UDP. You will need to baseline this counter by testing and monitoring the user load. |
| AudioVideoEdge_UDPAuthenticationFailureRate | AudioVideoEdge_UDPAuthenticationFailureRate | This component monitor returns the persecond rate of failed attempts to authenticate with the relay over UDP. The returned value should be as low as possible. |
| AudioVideoEdge_UDPAllocateRequestsExceedingPortLimit | AudioVideoEdge_UDPAllocateRequestsExceedingPortLimit | This component monitor returns the number of allocate requests over UDP that exceeded the port limit. If the value is greater than zero, this could indicate an attempt to misuse the port. This error occurs when there is an unexpectedly high rate of request. |
| AudioVideoEdge_UDPPacketReceiveRate | AudioVideoEdge_UDPPacketReceiveRate | This component monitor returns the number of packets received per second by the relay over UDP. You will need to baseline this counter by testing and monitoring the user load. |
| AudioVideoEdge_UDPPacketSentRate | AudioVideoEdge_UDPPacketSentRate | This component monitor returns the number of packets sent per second by the relay over UDP. You will need to baseline this counter by testing and monitoring the user load. |
| AudioVideoEdge_UDPAveragePacketLatency | AudioVideoEdge_UDPAveragePacketLatency | This component monitor returns the average latency for a valid data request over UDP in milliseconds. The returned value should be as low as possible. |
| AudioVideoEdge_UDPPacketDropRate | AudioVideoEdge_UDPPacketDropRate | This component monitor returns the persecond rate of packets over UDP dropped by the relay. The returned value should be as low as possible. This error occurs when an unexpectedly high rate of User Datagram Protocol (UDP) packets is received at the Media. |
| AudioVideoEdge_TCPActiveRelayAuthenticatedSessions | AudioVideoEdge_TCPActiveRelayAuthenticatedSessions | This component monitor returns the number of active relay sessions over TCP. |
| AudioVideoEdge_TCPActiveRelaySessionsWithAllocatedPort | AudioVideoEdge_TCPActiveRelaySessionsWithAllocatedPort | This component monitor returns the number of active relay sessions with a TCP port allocation. |

| AudioVideoEdge_TCPPortsInAllocatedPool | AudioVideoEdge_TCPPortsInAllocatedPool | This component monitor returns the number of TCP ports available in the Allocated Port Pool. This monitor should be more than zero. If it reaches zero there is a resource issue. |

| AudioVideoEdge_TCPAuthenticationFailureRate | AudioVideoEdge_TCPAuthenticationFailureRate | This component monitor returns the persecond rate of failed attempts to authenticate with the relay over TCP. The returned value should be as low as possible. |
| AudioVideoEdge_TCPAllocateRequestsExceedingPortLimit | AudioVideoEdge_TCPAllocateRequestsExceedingPortLimit | This component monitor returns the number of allocate requests over TCP that exceeded the port limit. If the value is greater than zero, this could indicate an attempt to misuse the port. This error occurs when there is an unexpectedly high rate of requests. |
| AudioVideoEdge_TCPPacketReceiveRate | AudioVideoEdge_TCPPacketReceiveRate | This component monitor returns the number of packets received per second by the relay over TCP. You will need to baseline this counter by testing and monitoring the user load. |
