Description

The keep-web buffer cache can cause a major performance bottleneck when it is not configured appropriately for the traffic load. This problem is more or less invisible from prometheus because we lack metrics

Add metrics for:

  • number of blocks in use in the WebDAVCache
  • block churn - can we expose # of blocks that were evicted from the cache while in use? If that's not possible, maybe just the # of cache evictions.
  • CollectionBytes in use in the WebDAVCache
