Dynatrace will discontinue support for PMI in Extension Framework 1.0 (EF1.0). We are currently working on replacement, that should be ready by end of the year. We will keep PMI EF1.0 functional until the new approach is ready and we'll provide sufficient grace period to migrate.
Performance Monitoring Infrastructure (PMI) is an IBM concept used mostly in context of WebSphere application server.
This means that PMI extensions need to be migrated around end of the 2024. Please already start planning that migration especially for custom extensions.
We do not yet have committed timeline.
For WebSphere connection pools please use new extension Connection Pools: WebSphere Liberty.
