Chapter 15. Managing using qdmanage

The qdmanage tool is a command-line tool for viewing and modifying the configuration of a running router at runtime.

Note

If you make a change to a router using qdmanage, the change takes effect immediately, but is lost if the router is stopped. If you want to make a permanent change to a router’s configuration, you must edit the router’s /etc/qpid-dispatch/qdrouterd.conf configuration file.

You can use qdmanage with the following syntax: 

$ qdmanage [<connection-options>] <operation> [<options>]

This specifies:

  • One or more optional connection options to specify the router on which to perform the operation, or to supply security credentials if the router only accepts secure connections.

    If you do not specify any connection options, qdmanage connects to the router listening on localhost and the default AMQP port (5672).

  • The operation to perform on the router.
  • One or more optional options to specify a configuration entity on which to perform the operation or how to format the command output.

When you enter a qdmanage command, it is executed as an AMQP management operation request, and then the response is returned as command output in JSON format.

For example, the following command executes a query operation on a router, and then returns the response in JSON format: 

$ qdmanage query --type listener
