Out of the boz the celery instrumentation doesn't seem to give number of tasks picked up etc. How to add those?

The number of tasks picked up can’t be show in the filter. That wouldn’t be the correct place. Depending on the instrumentation it will either be part of trace detail. Currently You can optionally write a ClickHouse SQL query to aggregate and plot them. There is no clever out-of-the box solution developed for this. Happy to help with the dashboard part if it’s not clear.
