Viewing the status of a telemetry channel

The status of a running telemetry channel provides information about the clients connected to it.

A telemetry channel status object can be purged. Purging an MQTT client connection disconnects the client from a telemetry channel and cleans up the state of the client. Cleaning the state of an MQTT client involves deleting all pending publications, and removing all subscriptions from that client.

Procedure

To view the status of a telemetry channel, perform the following steps:

1. In the Navigator view, expand the Telemetry folder, then click the Channels folder. Your telemetry channel definitions are displayed in the Content view.
2. Right-click the appropriate telemetry channel, then click Status. A new Content view opens in a separate window displaying the client connections on that telemetry channel.

Viewing all client connections to telemetry channels

It is possible to view all the client connections made to all telemetry channels on a queue manager. To do this, expand the Telemetry folder, then click the Channel status folder in the Navigator view.

All client connections to every telemetry channel on that queue manager are displayed in the Content view. We can reorder the display of objects by clicking the relevant column name to sort the results. Alternatively, we can use filtering.

By default, IBM MQ Explorer displays only the first 500 client connections. For more information about how to configure the maximum number of connections displayed at any given time, see Advanced option.

Note: To purge a telemetry channel status object, right-click the selected object and click Purge.
