keith-turner opened a new issue, #4492: URL: https://github.com/apache/accumulo/issues/4492
Metrics need to be emitted for the [scan block caches](https://github.com/apache/accumulo/blob/6d0b4768522187d8c43b9bf0850034d80a684235/server/tserver/src/main/java/org/apache/accumulo/tserver/TabletServerResourceManager.java#L121-L123) in order to tune them. Currently a message is logged w/ information about them but metrics would be much better. Metrics can be emitted based on [this information](https://github.com/apache/accumulo/blob/6d0b4768522187d8c43b9bf0850034d80a684235/core/src/main/java/org/apache/accumulo/core/spi/cache/BlockCache.java#L98-L114). It should be possible to compute the hit ratio over time of each block cache using the metrics data. -- This is an automated message from the Apache Git Service.
