Hi,

Do we have any reference link to view prometheus metrics for active session history.

Thanks.

Hi @explore_yb

Can you be more clear?

You want ASH in prometheus format?

Hi @dorian_yugabyte thats correct. I’m looking for prometheus metrics similar to active session history. If I enable Active Session History (ASH), then can I get the data in prometheus format, if yes is there any reference document to list ASH related Prometheus metrics ?

Time-series ASH-like metrics in Prometheus are currently supported via the new Performance Advisor, which is available as a Tech Preview in YBM 2024.2 and later. However, it’s not enabled by default — you’ll need to contact us to have it turned on for your account.

Once enabled, the Performance Advisor has its own internal Prometheus instance where time-series ASH data is extracted and stored. That said, direct access to this Prometheus instance is not yet publicly available, even in the Tech Preview.

We’re actively working on exposing this data for external use, including formal support for accessing ASH-related Prometheus metrics.
