Measures reported by BTSMTPSenTest

The Simple Mail Transfer Protocol (SMTP) adapter is used to exchange information between a BizTalk Server and other applications by means of the SMTP protocol. BizTalk Server can send messages to other applications by creating an e-mail message and delivering it to a specified e-mail address. The SMTP adapter consists of only one adapter, a send adapter. The send adapter controls the send ports that use the SMTP adapter. Internally, the SMTP send adapter creates an SMTP-based e-mail message and sends it to a target e-mail address. The target e-mail address is a property of the SMTP adapter. The SMTP send adapter gets messages from the server and posts them to an SMTP server that sends them to e-mail recipients.

This test helps you to figure out how quickly the SMTP send adapter sends out messages to other applications, and thus promptly detects slowdowns in message delivery.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Messagessent Indicates the total number of messages that are sent by the SMTP adapter on this host instance to the target e-mail address. Number The counter is incremented only for messages that have been transmitted to the SMTP server.
MessagessentSec Indicates the rate at which the messages are sent by the SMTP adapter on this host instance to the target e-mail address. Msgs/Sec The counter applies only to messages that have been transmitted to the SMTP server.

Ideally, the value of this measure should be high. A low value indicates that the SMTP send adapter is experiencing delays while sending messages to the target e-mail address. Further investigation may be required to diagnose the root-cause of the slowdown.
