Scylla - how to enable per table metrics?

Question

I am struggling in getting per-table metrics exported by Scylla version 5.2.9-0.20230920.5709d0043978. After quite a bit of research I found this Scylla Metrics readme, that says that those metrics are disabled by default. To enable it, enable-keyspace-column-family-metrics shall be set to 1 (or true) in scylla.yaml configuration file. Which I did, but still I do not see those metrics in the list at https://server:9180/metrics ...

Is the feature really working? is there any other way to enable such metrics natively (for now I managed to get them through JMX, but there must be a way to get them together with all other metrics - or at least I hope :) )

Answer 1

In scylla.yaml, you should replace dashes with underscores. So you should add this line to scylla.yaml:

enable_keyspace_column_family_metrics: true

Another way is to run scylla with this flag:

--enable-keyspace-column-family-metrics 1
