Measures reported by XchgPublicStoreTest

The Information store is responsible for data storage and management. It is the interface between the clients and the server running Exchange Server. There are two components of the Information Store, namely:

  • Mailboxes
  • Public Folders
The XchgPublicStoreTest reports statistics pertaining to the public folders of the Information store. The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Active_client_logons The number of active client logons into the Information store Number  
Client_logons The number of clients logging into their Information store Number This measure is a good indicator of user activity in the Exchange Server. This information can be used by the administrator for planning the capacity of the mail server.
Mail_send_qsize The number of messages in the send queue of an information store Number This measure is usually zero under normal conditions.

This measure can be non-zero in the case of very busy systems (2000 users and more).
Mail_rcvd_qsize This measure shows the number of messages 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.

Mails_open_rate This measure indicates the rate at which the requests to open the messages are being submitted to the information store. Mails/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.
Mails_sent_rate The rate at which mails are sent to the information store. Msgs/Min  
Avg_mail_delvry_time This measure indicates the average time between the submission of a message to the information store and the submission to other storage providers 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.

Note that this measure will not be available for an Exchange 2007 server.
Avg_mail_local_delvry_time This measure indicates the average time between the submission of a message to the information 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 the user workload.

An abnormally high value for this measure may indicate that the server is overloaded.
