# A generic metrics message providing statistics for measurements from different sources. For example,

# measure a system's CPU % for a given window yields the following data points over a window of time:

# - average cpu %

# - std deviation

# - min

# - max

# - sample count

# These are all represented as different 'StatisticDataPoint's.

# Name metric measurement source, e.g., node, topic, or process name

string measurement_source_name

# Name of the metric being measured, e.g. cpu_percentage, free_memory_mb, message_age, etc.

string metrics_source

# Unit of measure of the metric, e.g. percent, mb, seconds, etc.

string unit

# Measurement window start time

builtin_interfaces/Time window_start

# Measurement window end time

builtin_interfaces/Time window_stop

# A list of statistics data point, defined in StatisticDataPoint.msg
