I'm looking for a good way to monitor the Platform Events being published by our org, so I can check that they are actually being published and have the expected content.

On Azure, I could use the Microsoft Azure Service Bus Explorer to peek at (or retrieve or add to) messages in a Queue or Topic.

Is there anything similar for the Salesforce Event Bus?

    I have been reading about a lot of cool platform event monitoring implementations with Heroku. Might be something to look into, here is an example by Heroku github.com/heroku-examples/salesforce-streams-nodejs Commented Oct 9, 2020 at 19:54
  • @MaxGoldfarb, cheers for the suggestion. I'll need to take a closer look at this. :-) Commented Oct 9, 2020 at 21:34

    @MaxGoldfarb, Looked at it.... Unless I'm missing something, as-is, there is no support for monitoring custom events and it does not tell me about the contents of the event. BUT, I didn't know "Change Data Capture" which could actually be really useful for us. Cheers again for this! Commented Oct 10, 2020 at 17:38

Salesforce Labs came out with a decent, free package for this on the AppExchange:

Streaming Monitor

The Lightning App lets you monitor streaming events: PushTopic events, generic events, standard and custom platform events, Change Data Capture events, and monitoring events.

I've found it to be pretty useful. It has a 4.5 star rating on 22 reviews. Salesforce has continued to support/update it (latest release on 7/27/22).

From the AppExchange listing:


  • Subscribe to all streaming events (event types are automatically discovered)
  • Subscribe to and unsubscribe from specific streaming events with a user-friendly UI
  • Publish an event (generic events and platform events)
  • Register an event source (instructions and shortcuts)

Analyze past event content with:

  • timeline or table view
  • dynamic filters
  • flexible replay options

The app leverages the lightning-emp-api Lightning Web Component for streaming event subscriptions and D3.js to draw a dynamic event timeline.

  • Cheers for the response... I'm looking for something which can be used without access to any Salesforce Instance, but maybe this will do in a pinch if, for example, it might be used by some arbitrary person in a developer org.... Commented Sep 9, 2022 at 10:01
