How busy is your Matchbox server? Which validations are slow, and is it about to run out of memory? Through OpenTelemetry, the open standard that most monitoring tools support, Matchbox can now send its metrics, traces and logs to a monitoring platform such as Traceway, which collects them and gives you the answers. In this hands-on tutorial, Quentin shows how to set it up in a few minutes, build a dashboard and add alerts, so you always have a clear view of how your validation service is doing.
