During the testing with Grafana 11.3.0 and RabbitMQ 3.13.7, deployed on Kubernetes, we noticed several issues with the Erlang Distribution and Erlang BEAM dashboards.
Erlang Distribution dashboard:
The "State of distribution links" panel on the Erlang Distribution dashboard was failing due to a query error caused by duplicate series in the match group, resulting in many-to-many matching conflicts.
The "Process state" panel was unable to display correctly due to the flant status map being deprecated.
Erlang-BEAM dashboard:
Data was unable to be retrieved due to the missing DS_Prometheus variable, which was not defined as a datasource.
The "Erlang VM Run Queue Length" panel displayed data for all nodes in the cluster rather than filtering to show data only for the selected node.
Changes:
Updated the Erlang Distribution dashboard to refine instance filtering, preventing many-to-many matching errors.
Replaced the deprecated flant status map of "Process state" panel to status map.
On the Erlang-BEAM dashboard, defined the DS_Prometheus variable as a datasource to ensure accurate data retrieval.
Enhanced the "Erlang VM Run Queue Length" panel to filter data by the currently selected node.
