Interpretation |
|
Curr_users
|
Shows the actual number of users (not
connections) currently using the information store. |
Number
|
This measure is a good indicator of user activity in the Exchange 5.5
Server. This information can be used by the administrator for planning
the capacity of the mail server.
|
|
Mail_send_qsize
|
Indicates 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
|
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.
|
|
Mail_sent_rate
|
Indicates the rate at which messages are being
sent to other storage providers via the Message Transfer Agent (MTA).
MTA is a component of Microsoft Exchange Server
that sends and distributes information between Microsoft Exchange
Server systems or between Microsoft Exchange Server and a foreign
system. Each MTA is associated with one information store. |
Msgs/Min
|
A high value over a period for this measure
indicates the one of the following:
-
Microsoft Exchange MTA service is down
-
Microsoft Exchane MTA service is choking up
memory
-
The Exchange Server 5.5 is overloaded.
|
|
Mail_opens_rate
|
Indicates the rate at which the requests to open
the messages are being submitted to the private 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 Server 5.5
is overloaded.
|
|
Folder_opens_rate
|
Indicates
the rate at which requests, to open the folders are being submitted to
the public information store. |
Reqs/Sec
|
This measure is another good indicator of user activity on the mail
folders.
|
|
Avg_mail_delvry_time
|
Indicates the average time between the submission
of a message to the information store and the submission to the MTA
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.
|
|
Avg_mail_local_delvry_time
|
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.
