A lot of Necko histograms have expired and need to be removed from the codebase along with their accumulation code. Full list of expired histograms: https://groups.google.com/forum/#!topic/mozilla.dev.telemetry-alerts/Uw9svhVTrXk There are about a dozen expired Necko histograms in the list above: UDP_SOCKET_PARALLEL_CLOSE_COUNT DISK_CACHE_ LOCALDOMSTORAGE_ SESSIONDOMSTORAGE_
Honza/Michal: the majority of these probes are from the cache/localstorage. Can you verify that we're fine removing them all?
Michal should decide on these: NETWORK_CACHE_FS_TYPE NETWORK_CACHE_SIZE_FULL_FAT On these I vote to remove: CACHE_SERVICE_LOCK* NETWORK_DISK_CACHE_* DISK_CACHE_* LOCALDOMSTORAGE_* since our localStorage impl is far best of all browsers and I don't want to invest time in more optimizations any time sooner. we can introduce the probes again if needed ; I'll do the removal on these SESSIONDOMSTORAGE_*
(In reply to Honza Bambas (not reviewing) (:mayhemer) from comment #2) > Michal should decide on these: > NETWORK_CACHE_FS_TYPE > NETWORK_CACHE_SIZE_FULL_FAT These can be removed. The amount of data we've collected is enough.
