Houston Putman commented on SOLR-11795:
---------------------------------------
I agree that co-existing would be the best course of action.
The prometheus exporter is a wonderful tool to collect cluster-level metrics.
However, having node-level metrics surfaced via one endpoint can limit their
usefulness. Many cloud platforms offer autoscaling, by watching metrics for
each individual instance. We can't really use these easily without providing
Prometheus endpoints for each individual node.
I think the split also makes it easier for users to specify what metrics they
want, as well as consume their metrics. And given the number of service
discovery mechanisms that Prometheus has, I don't think it will be a large
burden on users to scrape the exporter as well as all individual Solr nodes.
