wfh@chromium.org src/net/disk_cache/OWNERS Critical error ids. Reported each time the disk backed blockfile cache encounters an error or a critical error. Warning: this histogram was expired from Oct 2020 to Sep 2021; data may be missing. ricea@chromium.org src/net/disk_cache/OWNERS The elapsed time since an entry evicted from the HTTP disk cache was last used (or created). Logged once for every entry that is evicted, but only when the value is less than a day. ricea@chromium.org src/net/disk_cache/OWNERS The rank of a single entry evicted from the HTTP disk cache. Logged once for every entry that is evicted. jam@chromium.org swarm-team@google.com The total time it takes to perform a read IO operation. This is emitted at each cache read, and measures from the IO thread to background thread, waiting for the disk read, and back to the IO thread. jam@chromium.org swarm-team@google.com The total time it takes to perform a write IO operation. This is emitted at each cache read, and measures from the IO thread to background thread, optionally waiting for the disk write, and back to the IO thread. ricea@chromium.org src/net/disk_cache/OWNERS The number of deleted entries trimmed from the cache in a single call to disk_cache::Eviction::TrimDeleted(). Logged one for every call to the method for the HTTP cache when not emptying the cache. Since this method will delete at most 20 entries in a single call, a value of 20 may mean it called itself back asynchronously. morlovich@chromium.org src/net/disk_cache/OWNERS Whenever an entry is looked for in the index hash table, reports whether it's in the right bucket. Sampled to report 1% of the time. chikamune@chromium.org chrome-loading@google.com Record whether disk_cache::MoveCache() succeeded or not to RestartCache on Windows.

When MoveFileEx() returns true, true is recorded. chikamune@chromium.org chrome-loading@google.com Record the Windows GetLastError after a failure of disk_cache::MoveCache(). This is recorded on each failure of MoveFileEx() to RestartCache.
