Exchange Public Stores Test

This test reports statistics pertaining to the public folders of the Information store.

Target of the test : An Exchange server 2000/2003/2007

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every Information store being monitored.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.


The IP address of the machine configured with the Mailbox server role.


The port number through which the Mailbox server communicates. The default is 6001.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Active client logons

The number of clients that performed any active in the last ten minute interval.



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.


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.


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.


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.

Messages queued for submission

The current number of submitted messages which are not yet processed by transport.



Messages opened

This measure indicates the rate at which the requests to open the messages are being submitted to the information store.


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.

Messages delivered

Indicates the current number of messages delivered to all recipients.



Messages sent

This measure indicates the rate at which messages are sent to transport by the information store.



Messages submitted

Indicates the rate at which mails are submitted by clients.



Receive queue size

This measure shows the number of messages that are currently in the receiving queue of the information.


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.



Slow FindRow Rate

Indicates the rate at which the slower FindRow needs to be used in the mailbox store.


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 receive queue

This measure indicates the number of replication messages waiting to be processed currently.


A consistent increase in this value could indicate a bottleneck in the processing of replication messages.
