Grafana dashboard: Open Liberty (mpFaultTolerance-3.x)
Description: Displays metrics collected by methods annotated with MicroProfile Fault Tolerance annotations

This dashboard visualizes in depth metrics for each of the different [MicroProfile Fault Tolerance 3.0](https://github.com/eclipse/microprofile-fault-tolerance/tree/3.0) annotations: Fallback, Retry, Timeout, Bulkhead, CircuitBreaker

The dashboard has been tested on Open Liberty running with the [mpFaultTolerance-3.0](https://openliberty.io/docs/21.0.0.3/reference/feature/mpFaultTolerance-3.0.html) and [mpMetrics-3.0](https://openliberty.io/docs/21.0.0.3/reference/feature/mpMetrics-3.0.html) features, but should work with any server which supports both MicroProfile Fault Tolerance 3.0 and [MicroProfile Metrics 3.0](https://github.com/eclipse/microprofile-metrics/tree/3.0) (which are both part of [MicroProfile 4.0](https://download.eclipse.org/microprofile/microprofile-4.0.1/microprofile-spec-4.0.1.html#microprofile4.0)).

**How to use:**
For instructions on how to set up OpenLiberty with a Grafana dashboard [see this blog post](https://openliberty.io/blog/2020/04/09/microprofile-3-3-open-liberty-20004.html#gra). The instructions are for MicroProfile 3.3 so be sure to use the mpMetrics-3.0 and mpFaultTolerance-3.0 features instead of mpMetrics-2.3 and install this dashboard rather than the one linked from the blog post.
