+# cache_write
+#
+# Count of times we attempted to write properties to Isolated
+# Persistent Storage. This metric is intended to help debug cache
+# problems.
+#
+# Because the storage is persistent, we expect that this metric will
+# be reported only once per device. However, if a) writing fails,
+# b) the device suffers filesystem corruption, or c) the device is
+# factory-reset, then the metric will be reported multiple times.
