libstatistics_collector

Description

This C++ library provides the following:

• A Collector interface for implementing classes that collect observed data and generate statistics for them

• A TopicStatisticsCollector interface for implementing classes that collect and perform measurements for ROS2 topic statistics. Classes for calculating ROS 2 message age and message period statistics are also implemented.

• A MovingAverageStatistics class for calculating moving average statistics

Quality Declaration

This package claims to be in the Quality Level 1 category, see the Quality Declaration for more details.
