Abstract

A messaging system capable of providing monitoring capabilities of mail services provided by a mail server is disclosed. Monitoring of mail services can be done automatically without requiring a local administrator to have knowledge about the specific implementation details about mail services that are provided by the mail server. In addition, the messaging system provides the ability to perform a variety of monitoring tasks remotely.

Claims

1. In a messaging system having a message server arranged to process messages for hosts in multiple host domains and that includes at least one message server component, a message server performance parameter monitor for monitoring a message server component performance parameter associated with the message server component, comprising:

a test message transmitter coupled to the message server component suitably arranged to transmit a test message to the message server component, wherein the test message corresponds to one of the multiple host domains;

a component message receiver coupled to the message performance parameter monitor suitably arranged to receive a component response message from the component that is based upon the test message;

an evaluator unit coupled to the component response message receiver arranged to determine the message server component performance parameter based upon the component response message and the test message;

a data store unit coupled to a comparator unit arranged to store the determined message server component performance parameter; and

a display device coupled to the data storage unit for displaying the determined message server component performance parameter.

2. A monitor as recited in claim 1, wherein the message is an email message and wherein the message server is an email server and wherein the message server component is an email server component.

3. A monitor as recited in claim 2, wherein the performance parameter is one of a plurality of email component performance parameters and wherein the email server component is one of a plurality of interconnected email server components.

4. A monitor as recited in claim 3, wherein at least one of the plurality of email server component performance parameters is a component response time.

5. A monitor as recited in claim 4, wherein the component response time is based upon a time period between the transmission of the test message from the test message transmitter and the receiving of the component response message by the component response message receiver as determined by the comparator.

6. A monitor as recited in claim 5, wherein the component response time is periodically recalculated.

7. A monitor as recited in claim 6,

wherein the email performance parameter monitor compares at least one of the periodically calculated response times with a threshold value response time that represents a response time expectation value; and

wherein the email performance parameter monitor operates to provide an error notification when the at least one measured response time exceeds the threshold value response time.

8. A monitor as recited in claim 2, wherein the mail server component is selected from the group comprising a transfer unit, a messaging store, and a directory server.

9. A monitor as recited in claim 2, wherein the mail performance monitor operates to monitor various virtual domain attributes associated with the one or more virtual host domains.

10. A monitor as recited in claim 9, wherein the various virtual domain attributes include IMAP, IMAPS, POP3, POP3S, LDAP, and SMTP.

11. A monitor as recited in claim 2, wherein the monitor operates to log email activities associated with one or more virtual host domains in the data storage.

12. A mail performance monitor as recited in claim 2, wherein the monitor operates to display monitoring information associated with one or more virtual host domains.

13. In an electronic messaging system,

a mail performance monitor suitable for monitoring the electronic mail services provided by an electronic mail server arranged to process mail messages for hosts in multiple host domains, the mail performance monitor providing a monitoring interface that can be used to initiate a set of monitoring commands to perform monitoring tasks associated with the mail services provided by one or more components of the mail server.

14. A mail performance monitor as recited in claim 13, wherein the set of the monitoring commands provides the ability to initiate a test mail message;

and wherein the monitoring interface can provide measurements of response times associated with of one or more components of the mail server when the test mail is initiated.

15. A mail performance monitor as recited in claim 14, wherein the set of the monitoring commands provides the ability to capture activities associated with one or more virtual host domains of the mail server in one or more log files;

and wherein the monitoring interface provides tools that can be used to analyze the one or more log files to generate error notifications.

16. A mail performance monitor as recited in claim 15, wherein the monitoring interface provides error notification for the mail services provided through one or more virtual host domains of the electronic mail server.

17. A mail performance monitor as recited in claim 16, wherein the set of the monitoring commands can be initiated to provide information about mail messaging resources associated with the mail server.

18. A computer readable media including computer program code for monitoring electronic mail services provided by a mail server for hosts in multiple host domains, the computer program code providing a monitoring interface that can be used to initiate a set of monitoring commands to perform monitoring tasks associated with the mail services provided by one or more components of the mail server.

19. A computer readable media as recited in claim 18, wherein the computer readable media further comprises:

computer program code for capturing activities of one or more virtual host domains of the electronic mail server in one or more log files;

computer program code for analyzing the one or more log files; and

computer program code for generating error notifications based on the analyzing the one or more log files.

20. A computer readable media as recited in claim 19, wherein the computer readable media further comprises:

computer program code for measuring response times associated with one or more components of the mail server.
