>                 Key: CASSANDRA-11994
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11994
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Metrics, Observability
>            Reporter: Patrick McFadin
>            Priority: Major
>              Labels: cql, operations

> This is an attempt to revive the concept introduced in CASSANDRA-3527. Instead of specifically targeting JMX metrics, simplify by just exposing metrics into CQL tables as a dynamic view. 
> Exposing these metrics will give operators vital insight without resorting to anything more than what is installed with Apache Cassandra. 
> The scope of these tickets is only for reading metrics with a SELECT command. The actual data model can be discussed in the comments below. 
> Some basic requirements I would propose:
>  - SELECT syntax should allow for single node or cluster wide statistics
>  - Aggregations should be supported (min, max, avg)
>  - Inside metric tables, future column additions should be automatically created when new metrics are added to a family
>  - Large schema changes such as deletes should be postponed to a major release
