BT SMTP Adapter Test

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.

Using this test, you can figure out how quickly the SMTP send adapter sends out messages to other applications, and thus promptly detect slowdowns in message delivery.

Target of the test : A BizTalk Server 2010

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each host instance on the BizTalk server being monitored

Configurable parameters for the test
Parameters Description

Test period

This indicates how often should the test be executed.

Host

The host for which this test is to be configured.

Port

The port at which the host listens to.

Ispassive

If this parameter is set to Yes, then it means that, by default, all BizTalk servers being monitored by the eG system are the passive servers of a BizTalk cluster. No alerts will be generated if the servers are not running. Measures will be reported as "Not applicable" by the agent if the servers are not up.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Messages sent

Indicates the total number of messages 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.

Messages sent

Indicates the rate at which messages were 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.
