@axelson if this is on Heroku, from command line use heroku pg:info DATABASE_URL and you’ll get something like this to see how many connections are being used. You can also see some statistics if you click on the PG addon in the Dashboard GUI for the app and go to the Diagnose tab. There you’ll see a limited set of query stats. There may be more you can do with the CLI under the heroku pg command if you check out their documentation. Hope that helps.
PS…FWIW the issue I was seeing in iex above is unrelated as I found out and I don’t want to clutter your thread with details…it was a PICNIC (Problem In Chair, Not In Computer)!
