Measures reported by XChgMailXferTest

The XChgMailXferTest monitors the performance of the local and remote queues in the Exchange 2000/2003/2007 Server. The measures made by this test are as follows:

Measurement Description Measurement 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.
