mcilwain	80f8f5ac7f	Add basic logging for async operation processing time ... We're already storing this as a metric, but on a registry of our scale these operations tend to only happen on a daily-ish basis, for which seeing results in logs is easier to deal with than metrics (and also still very light-weight). ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=160552291	2017-07-10 11:31:56 -04:00
mcilwain	bb67841884	Add metrics for async batch operation processing ... We want to know how long it's actually taking to process asynchronous contact/host deletions and DNS refreshes on host renames. This adds instrumentation. Five metrics are recorded as follows: * An incrementable metric for each async task processed (split out by type of task and result). * Two event metrics for processing time between when a task is enqueued and when it is processed -- tracked separately for contact/host deletion and DNS refresh on host rename. * Two event metrics for batch size every time the two mapreduces are run (this is usually 0). Tracked separately for contact/host deletion and DNS refresh on host rename. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=157001310	2017-06-05 18:17:09 -04:00
