Notifications are sent out to alert you whenever one or more of your performance budgets is crossed. We send alerts via email and to webhook endpoints like Slack and HipChat.
It's important to remember this only happens when the budget is crossed, either from under budget to over budget, or over budget to under budget. If your test is over budget 10 times or hours in a row, we only send a notification on the first crossover. We don't send 10 notifications. This is done to reduce spam.
If you think you should be getting notifications but you're not, check the following:
Did the budget cross the threshold? Check your performance budget charts. Notifications are only sent at the point at which the metric value crosses over or under the threshold.
Are notifications turned on? Open the Budget tab in your chart and make sure the "Send alerts for this budget" checkbox is checked.
Are you in the notification list? Check the "Notifications" section in your Settings and make sure your email address or webhook is listed.
Along with sending email, SpeedCurve can also push Slack alerts to a channel of your choosing. The alert includes a graph with the recent history for a performance budget so you have all the context right in Slack and can decide whether to investigate or not.
You can send performance budget alerts straight to your HipChat team. You'll get an alert in your HipChat team every time a performance budget alert is sent.
