Data Stream Capture

The TSM for Nortel DMS can capture all raw data sent from a device.

The raw data is stored in a log file and can be used for debugging purposes, to develop new features for the TSM, or to pass to other management systems that require the same data.

For each connection, the full data stream is stored in a file with the following naming convention:

streamcapturefile_host_port

To enable stream capture, set the StreamCaptureFile property or -streamcapturefile command line option.

Rotating Stream Capture Files

The TSM for Nortel DMS can rotate stream capture files; that is, write to a stream capture file that is saved and archived periodically when a predefined file size is reached.

To use this feature, set the maximum size for the stream capture file using the MaxStreamCapFileSize property and set the DateStreamCapture property to 1. When the DateStreamCapture property is set to 1, the TSM creates a stream capture file with the following naming convention:

 streamcapturefile_host_port_date_time

By appending the filename with a timestamp, the TSM avoids overwriting the old stream capture file. The maximum file size specified by the MaxStreamCapFileSize property acts as an upper limit for the stream capture file. If the TSM reads a stream whose size exceeds the remaining allowable space in the current stream capture file, it saves the current file and creates a new one, thus storing the whole stream in a single file.

If you do not specify a maximum size for the stream capture file, it grows indefinitely until the connection is closed. If the MaxStreamCapFileSize property is set and the DateStreamCapture property to 0, the TSM overwrites the stream capture file for that connection each time the maximum file size is reached.
