Exchange Roles and Performance Monitoring
Exchange Server Roles are used to group the performance monitoring parameters used by WhatsUp Gold to indicate the state of the Exchange server. A server role is a unit that logically groups the required features and components needed to perform a specific function in the messaging environment. By mirroring these roles in the Exchange Server monitor, the configuration of the monitor becomes a simple exercise of setting the threshold values associated with each Exchange Server Role you want to monitor.
Hub Transport Server Role thresholds
The following table lists the threshold settings available for the Hub Transport Server category:
Threshold |
Description |
Value |
Aggregate Delivery Queue |
The Aggregate Delivery Queue holds the aggregate value of all of the messages queued for delivery in all of the queues associated with the Hub Transport Server. |
Default: 3000 messages |
Active Remote Delivery Queue |
The Active Remote Delivery queue holds messages that are being delivered to a remote server using SMTP. |
Default: 250 messages |
Active Mailbox Delivery Queue |
The mailbox delivery queue holds messages that are being delivered to a mailbox server by using encrypted Exchange RPC. |
Default: 250 messages |
Submission Queue |
A persistent queue that is used by the categorizer to gather all messages that have to be resolved, routed, and processed by Transport agents |
Default: 100 |
Active Non-SMTP Delivery Queue |
The Active Non-SMTP Delivery queue holds messages that are being delivered to a remote server, using a protocol other than SMTP. |
Default: 100 |
Retry Mailbox Delivery Queue |
The Retry Mailbox Delivery Queue holds messages with a status of Retry that are being delivered using encrypted Exchange RPC. Messages are given a status of retry when the server cannot connect to the next hop. |
Default: 100 |
Retry Non-SMTP Delivery Queue |
The Retry Mailbox Delivery Queue holds messages with a status of Retry that are being delivered using a protocol other than SMTP. |
Default: 100 |
Retry Remote Delivery Queue |
The Retry Mailbox Delivery Queue holds messages with a status of Retry that are being delivered using SMTP. |
Default: 100 |
Unreachable Queue |
The Unreachable queue is a persistent queue that contains messages that cannot be routed to their destinations. |
Default: 100 |
Largest Delivery Queue |
The Largest Delivery queue identifies the largest of all of the delivery queues on the Exchange server. |
Default: 200 |
Poison Queue |
The poison message queue is a special queue that is used to isolate messages that are detected to be potentially harmful to the Exchange 2007 system after a server failure. |
Default: 0 |
Mailbox Server Role thresholds
The following table lists the threshold settings available for the Mailbox Server category:
Threshold |
Description |
Value |
RPC request currently executing within the information store process must be less than: |
Sets the maximum threshold for the number of executing Remote Procedure Calls (RPC) in the Information Store process. |
Default: 70 |
RPC Averaged Latency must not exceed: |
Sets the maximum threshold for average latency of the Remote Procedure Calls (RPC) in milliseconds |
Default: 25 |
RPC Number of Slow Packets must be less than: |
Sets the maximum threshold for the Remote Procedure Call (RPC) packets within the past 1024 packets with latencies longer than 2 seconds. |
Default: 3 |
Messages Queued for Submission (Mailbox) must be less than: |
Sets the maximum threshold for the number of submitted messages in the Mailbox that have not yet been processed by the transport layer. |
Default: 50 |
Messages Queued for Submission (Public) must be less than: |
Sets the maximum threshold for the number of submitted messages by that have not yet been processed by the transport layer. |
Default: 20 |
Replication Receive Queue Size must be less than: |
Sets the maximum threshold for the number of replication messages waiting to be processed. |
Default: 100 |
Slow Findrow Rate must not exceed: |
Sets the maximum threshold for the rate at which the slower FindRow needs to be used in the mailbox store. A higher value indicates that applications are searching mailboxes, directly affecting server performance. |
Default: 10 |
Number of search tasks created per second must be less than: |
Sets the maximum threshold for the number of search tasks created each second. |
Default: 10 |
Average Document Indexing Time must be less than: |
Sets the maximum threshold in seconds for the length of time it takes to index documents. This value is reported in milliseconds and converted to seconds for this comparison. |
Default: 30 |
Outlook Web Access Server Role thresholds
The following table describes the thresholds associated with the Outlook Web Access Server category:
Threshold |
Description |
Value |
Average Response Time |
Sets the threshold for the average time in milliseconds that elapses between the beginning and end of an OEH or ASPX request. |
Default: 100 milliseconds |
Average Search Time |
Sets the threshold for the average elapsed time waiting for a search to complete. |
Default: 100 milliseconds |
