Measurement
Unit |
Interpretation |
| Active_Client_Logons |
The number of clients that performed any active in the last ten minute interval. |
Number |
|
| Average_Delivery_Time |
This measure indicates the average time between the submission of a message to the public folder store and the delivery to all local recipients (recipients on the same server) for the last 10 messages. |
Secs |
A non-zero value for this measure indicates a change in user workload.
An abnormally high value for this measure indicates inability to deliver to one or more destinations. One of the possible reasons for this can be a network failure.
|
| Categorization_Count |
Indicates the number of categorizations that currently exist in the public folder store. |
Number |
Categorizations are created when a user creates a filtered view or performs a search. When the information store must maintain an excessive number of categorizations, performance can be affected.
|
| Client_Logons |
The number of clients currently logged on. |
Number |
This measure is a good indicator of the current user activity in the Exchange Server. This information can be used by the administrator for planning the capacity of the mail server.
|
| Msg_Queued_for_Subm |
The current number of submitted messages which are not yet processed by transport. |
Number |
|
| Msg_Opens_per_sec |
This measure indicates the rate at which the requests to open the messages are being submitted to the information store. |
Msgs/Sec |
This measure shows the overall picture of user activity. An abnormally high value for this measure may indicate that the Exchange 2000 Server is overloaded.
|
| Msg_Delivered_per_sec |
Indicates the current number of messages delivered to all recipients. |
Number |
|
| Messages_Sent_per_sec |
This measure indicates the rate at which messages are sent to transport by the information store. |
Msgs/Sec |
|
| Msg_Submitted_per_sec |
Indicates the rate at which mails are submitted by clients. |
Msgs/Sec |
|
| Receive_Queue_Size |
This measure shows the number of messages that are currently in the receiving queue of the information store. |
Number |
This measure is usually zero under normal conditions.
A non-zero value for this measure indicates that the SMTP service is choking up memory.
|
| Search_Task_Rate |
Indicates the number of search tasks created per second. |
Tasks/Sec |
|
| Slow_FindRow_Rate |
Indicates the rate at which the slower FindRow needs to be used in the mailbox store. |
Finds/Sec |
Higher values indicate applications are crawling or searching mailboxes, which is affecting server performance. These include desktop search engines, customer relationship management (CRM), or other third-party applications.
|
| Replication_Rcv_Queue |
This measure indicates the current number of replication messages waiting to be processed. |
Number |
A consistent increase in this value could indicate a bottleneck in the processing of replication messages.
|
| Rpc_Averaged_latency |
Indicates the average time it takes for a remote procedure call to return results from a Mailbox store, averaged over RPC calls in the last minute. |
MSec |
This value should be below .05 seconds at all times. A slowdown in RPC packet processing can adversely impact the user experience.
