Data acquisition

Each probe uses a different method to acquire data. Which method the probe uses depends on the target system from which it receives data.

The Probe for PDS Snyder receives a message that reports date, time, and severity. The message also indicates whether it is an alarm, event condition, or a multi-line report. It requires the device to have a serial cable installed from a serial port to the RS-232 port on a terminal server. The TSM then connects to the terminal server through a TCP/IP connection and receives alarms as they are logged to this device.

Reconnection attempts

If the TSM gets disconnected from the system, it tries to reconnect. You can specify how many times the TSM tries to reconnect using the ReconnectionAttempts property. If you set this property to 0, the TSM makes unlimited attempts to reconnect to the system.

Bounce and resynchronize

The TSM listens for bounce and resynchronize commands. The bounce command kills the connection to the specified network element and then immediately reconnects. The resynch command re-sends all the alarms from the specified network element since it was started.

Users can run the bounce and resynch commands from the command line from a TCP/IP socket.
Running the bounce command
The bounce command allows users to close and re-establish the TSM's connection to a particular device. The command format is: 
bounce -host hostname -port portnumber
When the command is issued, the TSM looks for the connection specified by the host and port parameters. If found, the TSM then closes that connection and goes into re-connection mode.
Running the resynch command
The resynch command allows users to force the TSM to send a resynchronization command to a device. The command to be sent is specified in the hosts file entry for that connection. The command format is: 
resynch -host hostname -port portnumber
When the command is issued, the TSM looks for the connection specified by the host and port parameters. If found, the TSM sends the resynch command to the specified network element.

Resynchronization

The TSM can make periodic resychronization requests while it is running. To specify the frequency with which it makes these attemps, use the ResynchInterval property.

Alternatively, you can specify that the TSM only sends one resynchronization request to the system, at startup. To do this, set the ResynchInterval property to 0 and set the ResynchOnStartUpOnly property to 1.
