Using DTrace to Monitor IMAP APPEND Times (Doc ID 1626519.1)

Goal

Doc ID 1348027.1 provides examples of how to monitor the internals of IMAP command response times as they are seen by the imapd process, but IMAP APPEND is implemented differently, making the former examples less meaningful. For one thing, most IMAP commands are a brief amount of data inbound from the client to the server and the timing of the response is what you care most about. But IMAP APPEND may contain a large amount of data from the client to the server and the time to receive that data may be a considerable part of the overall response time.

Also, if you are just starting to look at an IMAP response time problem, the better place to start would be:

• Using immonitor-access to Measure Messaging Server Response Time (Doc ID 1343053.1)
• Isolating Delays Sending or Receiving Mail (Doc ID 1567992.1)
