Stopped - The "Stop" button has been pushed, but the channel is still completing work. Once processing is complete, the channel stops.

Channel Controls

The IMTA Channel Properties channel distribution window provides a pull-down menu to change the state of the channel:

Start Channel: Starts the channel, so that it can begin processing messages. This option is not available if the channel has not been configured properly or if the channel is already running.

Restart Channel: Starts the channel, so that it can begin processing messages. This option is not available if the channel has not been configured properly or if the channel is already running.

Stop Channel: Stops the channel. This option is not available unless the channel is running. When a stop is requested, the channel finishes working on the current message before stopping.

Delete Channel: Delete the channel.

Displaying Channel Log Files

Channel logging events can be useful for network traffic analysis and problem troubleshooting. Each event represents the receipt or processing of a message.

Displaying Channel Log Files in Syslog

Logging is performed through the syslog facility. Syslog must be enabled on the system running SIMS to view these logs. You can view the following events in the syslog file:

Info - Normal authentication, including Login, Logout, and broken connection.

Notify - Identifies repeated Login failures and mailbox access errors.

Err - Shows fatal system error, including out of memory, unexpected signal, etc.

Alert - Shows fatal disk error, including possible mailbox corruption. This will not happen with routine filesystem full errors, which are recoverable.
