Measures reported by XChg7MailTest

This test monitors the availability and performance of a Microsoft Exchange 2007/2010/2013 mail server from an external perspective. The test mimics a mail client activity by using the Exchange Web Service for sending and receiving mails.

Note:

  • For this test to execute smoothly, the external agent executing the test should be in the same domain as the Exchange 2013/2016 server.

  • The external agent running this test should be installed on a Windows host that supports .Net 3.5 Framework.

    • The measures made by this test are as follows:

    Measurement Description Measurement Unit Interpretation
    Send_avail Indicates the availability of the mail server for receiving the mails sent by the test. Percent A value of 0 indicates that the test was not successful in sending a mail. Possible reasons for this could include the mail server being down, the network connection to the server not being available, or the test configuration information being incorrect.
    Sent_msgs Indicates the number of messages sent to the mail server. Number A value of -1 indicates that the mail server may be down or the configuration information may be incorrect.
    Sent_time Indicates time taken to send a mail from to the mail server. Secs A high value of this measure could indicate high network traffic or that the mail server is busy.
    Rcvd_avail Indicates the availability of the exchange server for sending mails to the mail client. Percent The value of 0 indicates that the test was not successful in receiving a mail message from the Exchange server. Possible reasons could be incorrect configuration information.
    Rcvd_msgs Indicates the number of messages received by the mail client from the mail server. Number The value of 0 indicates that the test was not successful in receiving mail messages from the Exchange server. The possible reasons could be:

    • The sent messages could be in the message queue of the mail server but not routed to the mail box
    • Configuration information may be incorrect
    • Network failure
    • The mail service may not be running in the user account
    Rcvd_time Indicates the time taken by the mail client to receive a mail from the mail server. Secs A high value in this measure indicates that the mail server is busy or the network traffic is high.
    Avg_roundtrip_time The average of the round trip time (the time lapse between transmission and reception of a message by the server) of all the messages received by the mail server during the last measurement period. Mins This is a key measure of quality of the mail service. An increase in Roundtrip_time may be indicative of a problem with the mail service. Possible reasons could include queuing failures, disk space being full, etc.
    Max_roundtrip_time The high water mark of the round trip time (the time lapse between transmission and reception of a message by the server) of all messages received by the mail server during the last measurement period. Mins If the value of the Rcvd_msgs measure is 1, then the the value of the Max_roundtrip_time measure will be the same as the Avg_roundtrip_time.
