[TiDB Usage Environment] Production Environment
[TiDB Version] v7.1.0
[Encountered Problem: Problem Phenomenon and Impact] Currently, from the monitor, we can only find the real memory usage of some TiKV components. There is no more detailed view available. Is there a simple way to obtain this information?

Not at the moment, let’s wait for future versions to improve. The tikv-detail monitoring has a memory trace that can show part of it, and then there’s the block cache in rocksdb.

I hope the product team can quickly implement the memory tracking feature for TiKV. I estimate that many customers need this, and many customers are already using hardware to handle the issue of increasing memory usage. :sweat_smile:

Reduce the block cache size a bit.

This method has been used, but it hasn’t completely solved the problem. I happen to have another question: In writeCF, is there a way to see the space occupied by the index and the space occupied by MVCC?

You can’t see it.
