Measures reported by BTFileSenTest

The File send adapter transmits messages from the message box database to a specified destination address (URL). You define the URL, which is a file path and file name, by using wildcard characters related to the message context properties. The File send adapter resolves the wildcard characters to the actual file name before writing the message to the file.

When writing a message to a file, the File send adapter gets the message content from the body part of the BizTalk message object. The File send adapter ignores other message parts in the BizTalk Message object. After the File adapter writes the message to a file, it deletes the message from the MessageBox database. The File adapter writes files to the file system either directly or by using the file system cache, which can improve performance, particularly for large files.

This test monitors the outflow of data and messages from the file send adapter on each host instance and reports the load on the adapter and the slowdowns (if any) suffered by the adapter while processing the load.

 The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Bytessent Indicates the total number of bytes sent by the file send adapter on this host instance. Bytes The counter is incremented only for messages that have been completely written to file system.

BytessentSec Indicates the rate at which the bytes are sent by the file send adapter on this host instance. Bytes/Sec The counter applies only to messages that have been completely written to file system.
Messagessent Indicates the number of messages sent by the file send adapter on this host instance. Number The counter is incremented only for messages that have been completely written to file system.
MessagessentSec Indicates the rate at which the messages are sent by the file send adapter on this host instance. Msgs/sec The counter applies only to messages that have been completely written to file system.

Ideally, the value of this measure should be high. A low value indicates that the file send adapter is experiencing delays while writing files to the file system. Further investigation may be required to diagnose the root-cause of the slowdown.
