Create and configure a telemetry channel

A telemetry channel connects a number of MQTT clients to IBM MQ . Create one or more telemetry channels on a queue manager. Each of these telemetry channels might have different configuration settings, making it easier to manage the clients attached to them.

Procedure

Create and configure a new telemetry channel by completing the following steps:

1. Right-click the telemetry Channels folder and click New > Telemetry channel. The New Telemetry Channel wizard opens.
2. Type the name of the channel in the Channel name field. The names of telemetry channels are restricted to 20 characters. The characters that can be used in a telemetry channel name, as with all IBM MQ names, are:
   • Uppercase A-Z
   • Lowercase a-z
   • Numerics 0-9
   • Period (.)
   • Underscore (_)
   • Forward slash (/)
   • Percent sign (%)

   Leading or embedded blanks are not allowed.

3. Type the port number in the Port number field. The default port number for a telemetry channel without TLS security is 1883.
4. Optional: If you choose to secure your new telemetry channel using TLS, select Secure channel using SSL. The port number changes to 8883, which is the default for a channel secured using TLS.
   1. Click Next.
   2. Type the name of the SSL/TLS file to use in the SSL Key File field.
   3. Type the password to unlock the key file in the SSL Passphrase field.
   4. Select Identify client using digital certificate to force all clients to send their privately signed digital certificate for authentication, or select Allow anonymous clients to stop the telemetry channel from authenticating the client using TLS.

5. Click Next.
6. Select one of the following options for client authentication:
   • Don't check client supplied username and password: Select this option if we want your program to either perform its own authentication, or we do not need any clients authenticated.
   • Check client supplied username and password (using JAAS): Select this option to verify the identity of the client using JASS. Select the name of the JAAS configuration we want to implement from the JAAS config name menu.

7. Click Next.
8. Select from one of the following menu options:
   • Select MQTT Client ID to use the supplied MQTT client ID.
   • Select Fixed user ID to disregard whatever user ID is supplied by the client. Type your preferred user ID in the User ID field. The default value is Guest on Windows systems, and nobody on Linux systems.
   • Select Username provided by client to use the user name supplied in by the client. If no user name is supplied, the client fails to connect to IBM MQ.

9. Click Next.
10. Optional: Select Launch MQTT client utility to launch the graphical utility to test the MQTT protocol.
11. Review the list of actions to be performed and click Finish.

Results

A new telemetry channel is created. View this channel by expanding the Telemetry folder and clicking the Channels folder.

What to do next

We can now manage your telemetry channel authorities.
