From 51a9283984b05511bd98f9bcbd1f2f18900239cc Mon Sep 17 00:00:00 2001 From: Eric Holk Date: Mon, 7 Dec 2020 15:07:00 -0800 Subject: [metrics] Add file output support Adds a new command line option, -Xwrite-metrics-to-file=_, which specifies a file for writing metrics to. This can be used in conjunction with -Xwrite-metrics-to-log, which will cause the output to go to both logcat and the file. Writing metrics to a file can be helpful for testing or benchmarking environments. Access to the file is protected using advisory locking, so it is safe to have multiple processes write metrics to the same file.
