Rules - Performance Monitoring

Exchange 2013, 2016 and 2019

  • Message Bytes Recvd/Second- Monitors the rate messages are received by the transport component. Compare this counter to a system baseline to determine the healthy output.
  • Message Bytes Sent/Second- Check the total size of messages in bytes are sent per second. Compare this counter to a system baseline to determine the healthy output. - Disabled on Edge Transport Role for Exchange 2016 and 2019.
  • Message Delivered/Second- The number of messages delivered to the database per second. - Disabled on Edge Transport Role for Exchange 2016 and 2019.
  • RPC Requests - The number of client requests currently being processed by the store, which should typically be below 25. - Disabled on Edge Transport Role for Exchange 2016 and 2019.
  • Send Queue Items- The number of messages currently queued. Assure that the send queue is empty (0) at least once in the set period.

All Versions of Exchange (2003, 2007, 2010)

  • checkRPCRequests
    Exchange Store RPC Requests - The number of client requests currently being processed by the store, which should typically be below 25.
  • checkMessagesSent/Sec
    Messages Sent/Sec - Monitors the rate messages sent to transport component. Compare this counter to a system baseline to determine the healthy output.
  • checkReceivedQueueSize
    Receive Queue Size - Check for the number of queued messages, inbound from the information store. Compare this counter to a system baseline to determine the healthy output.
  • checkMessagesRecvd/Sec
    Messages Received/Sec - Monitors the rate messages are received by the transport component. Compare this counter to a system baseline to determine the healthy output.
  • checkMessageBytesSent/Second
    Message Bytes Sent/Second - Check the total size of messages in bytes are sent per second. Compare this counter to a system baseline to determine the healthy output.
  • checkMessageBytesRecvd/Second
    Message Bytes Recvd/Second - Check the total receive rate for inbound messages. Compare this counter to a system baseline to determine whether the output rate is healthy.

Exchange 2003 Only

  • checkSendQueueSize
    Send Queue Size - Monitors the queue of messages outbound from the Information Store. In cases where the SMTP service or the Message Transfer Agent (MTA) is down, or is experiencing a reduction in performance, there will be a non-zero value for this queue. Under normal operating conditions, this queue should not stay at a non-zero value for any significant length of time except for large systems of more than 2000 users, where the value will never be zero.
  • checkLocalQueueLength
    The Local Queue Length is the number of messages in the SMTP queue awaiting local delivery. As a guideline, the maximum value should be less than 1,000.
  • checkCategorizerQueueLength
    Exchange Transport Categorizer Queue Length is the number of messages waiting for advanced address resolution to occur before the message can be stored in the local queue or sent to the routing engine for delivery. A high number indicates a message flow problem within the intranet.
  • checkInboundConnectionsCurrent
    Inbound Connections Current - Monitor the number of inbound connections to the Exchange Server. A reading of 0 for an extended time can indicate network problems.
  • checkAvgRetries/MsgsDelivered
    Avg Retries/Msgs Delivered - Monitors the average number of retries per local delivery, shown as the number of retried messages as a fraction of the overall message delivered. Mail delivery problems are evident if the average number increases.
  • checkAvgRetries/MsgsSent
    Avg Retries/Msgs Sent (checkAvgRetries/MsgsSent) - Monitors the average number of retries per outbound messages sent, if this increases then it will indicate send message problems. Number of retried messages as a fraction of the overall messages sent.
  • checkAddressListQueueLength
    Address List Queue Length - Monitors the load on the Recipient Update Service, this usually exists on the first Exchange Server installed within the domain. Enabling this rule on any other Exchange server will result in the error Object reference not set to an instance of an object.
