Magicians never share their secrets. But we do. Sign up for our Ruby Magic email series and receive deep insights about garbage collection, memory allocation, concurrency and much more.
We’re releasing Anomaly Detection today. With this much-requested feature, you can set up triggers to be alerted when metrics exceed a specific range.
We are shipping this feature as beta with the most common use case: Error rate alerts. You can set triggers per namespace to receive an alert when your error rates go over a specified value and we'll notify you again when everything's back to normal. After you’ve been alerted, AppSignal shows you exactly which errors occurred within that timeframe. During the beta, alerts are only sent to Slack.
We will add more integrations soon. We plan to expand the triggers section in the future so you can set triggers on metrics like throughput, performance, host metrics and custom metrics. Adding warm-up and cooldown periods and more trigger conditions (over, under, between, equal to) are also on our roadmap.
Error rate alerts are the first step to a smarter way of being notified about issues in your applications. We're curious to hear what you think. Please let us know (firstname.lastname@example.org / @AppSignal) if you if you have any questions or suggestions!
