Diagnostics is a new tool that allows admins to get a quick overview of the health of their system. A lot of performance issues can be attributed to third-party apps, and particularly apps with behavior that we know is problematic.

The new diagnostics tool aims to:

  • provide early performance feedback to product developers and developers of third-party apps, allowing performance issues to be detected earlier.
  • provide performance data to support staff, to help analyze performance issues reported by customers more quickly.

Eventually, we hope the performance data collected will also help with recovering from performance problems, such as isolating badly behaving apps from core components and in extreme cases, completely disabling apps.

The end goal is to improve performance and stability at scale.

Diagnostics currently displays a summary of the alerts that have been raised in the past 30 days, with three levels of severity: 

  • Error: a serious problem has occurred that impacts system stability and/or availability.
  • Warning: an issue has been detected that impacts performance or can lead to more serious problems in the future.
  • Info: something worth noting.

The events are filterable so you can check against a particular date or time, or simply filter by node. Click into the event to see the event details. For more information, read the diagnostics overview, or the event details page.

JMX metrics for diagnostics

The JMX metrics for diagnostics alerts can be found in the Bitbucket Server documentation, under Enabling JMX counters for performance monitoring
