One npx command to see why your website is slow (New Relic + Sentry on localhost)

·1 views

I'm building MetricFlow, a performance dashboard for your website that runs on your own machine. It shows real-user metrics from New Relic and JavaScript errors from Sentry side by side, per page, and can suggest what to fix first. npx @karan171996/metricflow That opens a dashboard at http://localhost:3000. There is no MetricFlow server and no account to create. Your keys stay on your machine.

CogniRunner 3.3.0: it no longer waits for a transition

CogniRunner 3.3.0: it no longer waits for a transition Key takeaways CogniRunner 3.3.0 (Marketplace, 7 September) adds listeners and scheduled jobs. Until now every rule needed a workflow transition to fire; now a rule can react to any of 68 Jira events or run on a five-field cron in an IANA time zone. Loops are the failure mode of event automation, so the guard rails are on by default: self-generated events are ignored unless you say otherwise, and brakes cap a listener at 120 runs and an issue at 30 runs in any five-minute window. Redelivery and loops are different problems. A brake counts r
