Hello, Igniters.
I faced the following problem with the metrics - JmxMetricExporter fails
to export discovery metrics (ticket - [1]).
The main reason: JMX exporter assumes that each metric name must start
with the name of the registry it belongs to, but discovery metrics do
not obey this naming convection.
I propose to formalize the names of the metrics included in the metrics
registry so that they always start with the name of the register. And
add corresponding assertions (ticket - [2]).
It helps to make the metric naming consistent and fixes the mentioned
above issue.
The following metric names are proposed to be changed:
JoinedNodes -> io.discovery.JoinedNodes
LeftNodes -> io.discovery.LeftNodes
FailedNodes -> io.discovery.FailedNodes
PendingMessagesRegistered -> io.discovery.PendingMessagesRegistered
CommunicationErrors -> io.discovery.CommunicationErrors
CurrentTopologyVersion -> io.discovery.CurrentTopologyVersion
Any objections?
