Query events using the Actyx Query Language (AQL)

AQL allows you to select, filter, and transform event streams. Here are a couple of examples.

All events

FROM allEvents

node-manager-query-from-all-events

Filter by tags

FROM 'a' & 'a:2'

node-manager-query-filter-by-tags

Transform payloads

FROM 'a' & 'a:2' SELECT _.key

Export events

If you want to perform further analysis of events, or just use some of them somewhere else, simply select the events you are interested it and copy them to your clipboard. Then paste them — it's an array of JSON objects — anywhere else.

Errors and warnings

If you query tries to access unknown properties, or performs illegal transformations (e.g. divide by zero), a warning or error message will be shown for each affected result:
