# thermal_limiting_elapsed_time

# Records the duration in seconds of a period of thermal limiting

# thermal_limit_result
#
# Log the result of thermal mitigation. When the device is being
# thermally limited, we will either exit limiting after successful
# mitigation, or by device reboot if mitigation was not successful.
# Entering thermal mitigation indicates the device is operating at a
# higher temperature than is desired or expected, and should
# therefore be considered a generally rare event without an estimate
# on frequency.

# raw_temperature
#
# Records the raw temperature as seen by the PowerManager at each
# iteration of the thermal policy. The 'sensor' dimension is used to
# select and identify which temperature sensor the metric is referring
# to. The histogram data is flushed to Cobalt after 100 iterations
# (100 seconds).
