Show aggregate table metrics per cluster #2363

Open hopugop opened 1 month ago

hopugop commented 1 month ago

Describe the feature and the current behavior/state. Table metrics are amazing. However, it only allows to choose from a single table at a time. It would be really useful to allow a view for all tables in a single view - think of it like a historical view of tables' operations, latency and dataset.

I recently used raw queries to achieve this, such as sum(scylla_column_family_total_disk_space{}) by(dc,ks,table) to aggregate disk utilization by table. There might be many others beneficial uses.

Who will benefit with this feature? Anyone that is interested in historical metrics comparison for multiple tables.

It makes sense to aggregate (sum? avg?) specific data from multiple tables - such as disk space. What else? Latency or ops make little sense to me.
