Sarma Pydipally commented on CASSANDRA-17968:
---------------------------------------------
[~brandon.williams] i dont know what is "[Prometheus exposition
format|https://prometheus.io/docs/instrumenting/exposition_formats/]"; but i
guess you are right. i am asking for a config which will allow cassandra
dropwizard metrics to be written to a text file but readable by prometheus
exporter so can be fed directly into prometheus.
> Dropwizard metrics output in Prometheus format
> ----------------------------------------------

> Key: CASSANDRA-17968
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17968
> Project: Cassandra
> Issue Type: Improvement
> Components: Observability/Metrics
> Reporter: Sarma Pydipally
> Priority: Normal
>
> in Apache Cassandra :
> we already have Dropwizard metrics module pre-integrated. I wrote about it on
> my GitHub :
> https://github.com/sarma1807/Prometheus-Grafana-Cassandra/tree/main/01_Cassandra_metrics-reporter
> we should have a feature where Cassandra Dropwizard module can directly write
> these metrics into Prometheus format.
> then we can feed those metrics directly to Prometheus for metrics collection.
> we do not have to expose this as a webservice - instead of writing just
> metrics in plain text ... it should write in Prometheus format into a file on
> each server.
