BT Http Send Adapter Test

The HTTP send adapter gets messages from BizTalk Server and sends them to a destination URL on an HTTP POST request. The HTTP send adapter gets the message content from the body part of the BizTalk Message object. The HTTP send adapter ignores all other parts of the BizTalk Message object.

Using this test, you can monitor the flow of messages to and from the HTTP send adapter for each host instance on the BizTalk server. In the process, you can determine the current workload of the HTTP send adapter of a host instance, and evaluate the load processing ability of that adapter.

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 received	Indicates the total number of HTTP response messages received by the HTTP send adapter on this host instance.	Number	The counter is incremented after a response message is completely read by the HTTP send adapter from HTTP servers.
Messages received rate	Indicates the rate at which HTTP response messages are received by the HTTP send adapter on this host instance.	Msgs/Sec	The counter applies only to response messages that have been completely read by the HTTP send adapter. Ideally, the value of this measure should be high. A low value indicates that the HTTP send adapter is experiencing delays while receiving messages from the BizTalk server. Further investigation may be required to diagnose the root-cause of the slowdown.
Messages sent	Indicates the total number of HTTP requests sent by the HTTP send adapter on this host instance to the destination URL.	Number	The counter is incremented only for request messages that have reached the destination URL.
Messages sent rate	Indicates the rate at which HTTP requests were sent by the HTTP send adapter on this host instance to the destination URL.	Msgs/Sec	The counter applies only to request messages that have reached the destination URL. Ideally, the value of this measure should be high. A low value indicates that the HTTP send adapter is experiencing delays while sending messages to the destination URL on an HTTP POST request. Further investigation may be required to diagnose the root-cause of the slowdown.
