  "message": "Make cache disk stat metric computation optional\n\nComputing the disc stat metrics for persistent caches is very expensive\nand can block a thread for several minutes on larger installations.\n\nThis change adds a configuration option to enable the computation of\nthe disk stats. This option is set to false by default. This makes the\nchange a breaking change, which will affect users that use the\ncaches_disk_.* metrics. However, since computing this metric can block\nmultiple threads depending on metric scrape rate and thus even cause\noutages, it makes sense to not enable this by default.\n\nChange-Id: I41ee2d9a368c312b7b2729d17d6c19bee0d90922\n",
