• recipients of the queued messages,
• active connections to remote MTAs,
By selecting a Switch, Channel or Peer MTA item you can use an option from the popup
menu (launched using the right mouse button) to access the configuration of that item in
the Directory.
If you have authenticated as a suitably privileged user you can not only view the above
entities, but also manage the entities. For a description of SASL IDs and authentication
see M-Switch Administration Guide).
5.2 Management and Monitoring
5.2.1 Message Switch
A Message Switch object shown on the right-hand side of the Switch Operations View
represents the Switch as a whole. It presents information about the overall peformance and
status of the Switch, and allows the following operations to be performed:
• Edit switch configuration. This opens (or switches to) the Switch Configuration
Management view, and selects the configuration entry for the Message Switch.
• Increase the maximum operation rate. This allows the MTA to perform more operations
per second, increasing the amount of system resources that the MTA uses.
• Decrease the maximum operation rate, reducing the amount of system resources that the
MTA uses.
• Enable submission: allow messages to be submitted normally again, after submission
has been disabled.
• Disable submission: this prevents messages being submitted into the MTA. Use of this
control might be useful if the MTA was being flooded with message submission.
• Enable all channels in a single operation.
• Disable all channels in a single operation.
• Check routing. This allows the user to determine how the MTA would route an address.
• Reload message queue. This causes the Queue Manager to re-read all messages which
are currently held on disk in the message queue.
• Reprocess queue. This causes the Queue Manager to perform a routing calculation for
each recipient of every message currently queued. If routing or other configuration
changes have been made since messages were queued, this may cause messages to be
requeued on different channels or for transfer to different Peer MTAs.
• Reload configuration. This causes the Queue Manager to check its configuration entry
in the Directory for configuration changes, and reload it if necessary.
• Shutdown. This causes the Queue Manager to terminate.
5.2.2 Channel
The following operations can be performed on individual channels:
• Alter channel configuration. This opens (or switches to) the Switch Configuration
Management view, and selects the configuration entry for the channel.
• Enable the channel.
• Disable the channel. This prevents the channel from processing any messages which are
queued on it.
