Maxim Muzafarov reassigned CASSANDRA-11994: ------------------------------------------- Assignee: Maxim Muzafarov > Expose metrics via CQL interface > -------------------------------- > > Key: CASSANDRA-11994 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11994 > Project: Cassandra > Issue Type: Bug > Components: Legacy/Observability, Observability/Metrics > Reporter: Patrick McFadin > Assignee: Maxim Muzafarov > Priority: Normal > 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 -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
