Exchange 2013 Client Access Role Counters (Advanced)

Version 2

    This template contains advanced performance and statistics counters for monitoring Exchange 2013 Client Access Role. Some of the counters may require manual configuration, such as correcting thresholds for the client’s environment. Use this template in addition to the Exchange 2013 Client Access Role Services and Counters (Basic) template.


    Prerequisites:
    RPC and WMI access to the Exchange server.

    Credentials: Windows Administrator on target server.


    Monitored Components

    ASP.NET: Application Restarts

    This monitor shows the number of times the application has been restarted during the Web server's lifetime. The returned value should be 0 at all times.

    Note: This monitor has the Count Statistic As Difference option enabled. Only values from last poll will be returned.

     

    ASP.NET: Worker Process Restarts

    This monitor shows the number of times a worker process has restarted on the computer. The returned value should be 0 at all times.

    Note: This monitor has the Count Statistic As Difference option enabled. Only values from last poll will be returned.

     

    ASP.NET: Request Wait Time

    This monitor shows the number of ms the most recent request was waiting in the queue. The returned value should be 0 at all times. Values greater than 0 should be investigated.

     

    Address Book: NSPI RPC Browse Requests Average Latency

    This monitor shows the average time, in ms, that Name Service Provider Interface (NSPI) browse requests took to complete during the sampling period. The returned value should be below 1,000ms.

     

    Address Book: NSPI RPC Requests Average Latency

    This monitor shows the average time, in ms, that NSPI requests took to complete during the sampling period. The returned value should be below 1,000ms.

     

    Address Book: Referral RPC Requests Average Latency

    This monitor shows the average time, in ms, that referral requests took to complete during the sampling period. The returned value should be below 1,000ms.

     

    Control Panel: Outbound Proxy Requests - Average Response Time

    This monitor shows the average time (in ms) that requests sent to a secondary Client Access server took to complete during the sampling period. The average returned value should be under 6,000ms.


    Control Panel: Requests - Average Response Time

    This monitor shows the average time (in ms) the Exchange Control Panel took to respond to a request during the sampling period. The average returned value should be under 6,000ms.

     

    Active Sync: Requests/sec

    This monitor shows the number of HTTP requests received from the client via ASP.NET per second. This determines the current Exchange ActiveSync request rate.

     

    Active Sync: Ping Commands Pending

    This monitor shows the number of ping commands currently pending on the server. Ping Commands Pending and Sync Commands Pending are the number of hanging requests, which should be almost equal to the number of Direct Push and hanging sync users.

     

    Active Sync: Sync Commands Pending

    This monitor shows the number of sync commands currently pending on the server. Ping Commands Pending and Sync Commands Pending are the number of hanging requests, which should be almost equal to the number of Direct Push and hanging sync users.

     

    Active Sync: Current Requests

    This monitor shows the number of HTTP requests waiting to be assigned to a thread. Average returned values should be between 50–100.

     

    Availability Service: Availability Requests (sec)

    This monitor shows the number of requests serviced per second. The request can be only for free/ busy information or include suggestions. One request may contain multiple mailboxes. This determines the rate at which Availability service requests are occurring.

     

    OWA: Current Unique Users

    This monitor shows the number of unique users currently logged on to Outlook Web App. This value monitors the number of unique active user sessions, so that users are only removed from this counter after they log off or their session times out. This determines current user load.

     

    OWA: Requests/sec

    This monitor shows the number of requests handled by Outlook Web App per second. This determines current user load.


    Autodiscover: Requests/sec

    This monitor shows the number of Autodiscover service requests processed each second. This determines current user load.

     

    Web Service: Requests/sec

    This monitor shows the number of requests processed each second. This determines current user load.

     

    Web Service: Current Connections

    This monitor shows the current number of connections established with the Web service. This determines current user load.

     

    Web Service: Connection Attempts/sec

    This monitor shows the rate that connections to the Web service are being attempted. This determines current user load.

     

    Rpc Client Access: Active User Count

    This monitor shows the number of unique users that have shown some activity in the last two minutes.

     

    Rpc Client Access: User Count

    This monitor shows the number of users connected to the service.

     

    Rpc Client Access: RPC Operations/sec

    This monitor shows the rate at which RPC operations occur, per second.

     

    UM Availability: % of Failed Mailbox Connection Attempts Over the Last Hour

    This monitor shows the percentage of mailbox connection attempts that have failed in the last hour. The returned value should be less than 5%.

     

    UM Availability: % of Inbound Calls Rejected by the UM Service Over the Last Hour

    This monitor shows the percentage of inbound calls that were rejected by the Microsoft Exchange Unified Messaging service over the last hour. The returned value should be less than 5%.

     

    UM Availability: % of Inbound Calls Rejected by the UM Worker Process Over the Last Hour

    This monitor shows the percentage of inbound calls that were rejected by the UM worker process over the last hour. The returned value should be less than 5%.

     

    UM Availability: % of Messages Successfully Processed Over the Last Hour

    This monitor shows the percentage of messages that were successfully processed by the Microsoft Exchange Unified Messaging service over the last hour. The returned value should be greater or equal to 95%
