Unit |
Interpretation |
| Local_qsize
|
This measure
indicates the number of messages in the local queue. |
Number
|
This measure is rarely greater than zero under normal operating
conditions.
A non-zero value for this measure indicates that the server is
receiving more messages than it can process and distribute.
If this measure increases steadily over a period, there is probably
a problem with the information store to which the user is trying to
deliver.
|
| Remote_qsize
|
This measure
indicates the number of messages in the remote queue. |
Number
|
This measure is rarely greater than zero under normal operating
conditions.
If this measure increases steadily over a period, there is probably
a problem with the remote information store to which the user is
trying to deliver.
The value of this measure may increase if mails are sent to
different domains.
|
| Curr_smtp_conn
|
This measure
shows the total number of current inbound connections. |
Number
|
A zero value for this measure either indicates that no SMTP clients
are accessing the Exchange 2000/2003/2007 Server or some network problems exist
that is blocking the user requests.
A substantial high value for this measure indicates that the SMTP
server is overloaded.
This problem can be solved by limiting the number of connections to
the SMTP virtual server in the Exchange System Manager.
|
| Bad_mail_msgs
|
This measure
indicates the number of bad mails generated. |
Number
|
A non-zero value for this measure indicates that the mails are not
delivered to the destination.
This situation may arise due to one of the following reasons:
1. No recipients might have been
mentioned for the mail
2. A network failure
3. A general failure in the Exchange
2000 Server
|
| Data_rcvd_rate
|
This measure
shows the rate at which the Exchange 2000/2003/2007 Server receives data. |
KB/Sec
|
An above normal value for this measure over a period may indicate that
the SMTP server is overloaded.
Limiting the number of simultaneous connections to the SMTP virtual
server in the Exchange System Manager can solve this problem.
|
| Data_sent_rate
|
This measure
shows the rate at which the Exchange 2000/2003/2007 Server sends data. |
KB/Sec
|
A high value over a period is indicative of an excessive use of the
SMTP server.
Limiting the number of simultaneous connections to the SMTP virtual
server in the Exchange System Manager can solve this problem.
|
| Avg_retry_msg_delvry
|
Messages that
could not be delivered by the Exchange 2000/2003/2007 Server are sent to the
retry queue.
This measure indicates the number of messages entering the retry
queue as a fraction of the overall message delivery.
|
Number
|
This measure is a good indicator of the general message delivery
problems in the target environment.
This measure should be close to zero.
If a large number of messages are being retried, this measure will
approach to 1.
|
| Avg_retry_msg_sent
|
This measure
shows the average number of retries sent as a
fraction of the overall messages that is being sent from the Exchange
server. |
Number
|
This measure should be close to zero under normal operating
conditions.
If a large proportion of the sent messages are entering the retry
queue, this measure will approach 1.
