RMW Stats Shim
Depends on a modified version of rmw_implementation to provide topic statistics calculation within the RMW layer of each node, without having to instrument application code.
This component
- Wraps & intercepts some RMW API calls
- Calculates “published period” statistics for every Publisher
- Calculates “received period” statistics for every Subscription
- Calculates “take age” statistics for every Subscription
- This is the different between publish system timestamp and the time at which
rmw_takeis called, so is the sum of network latency plus executor latency
- This is the different between publish system timestamp and the time at which
- Creates a
/topic_statisticsPublisher for every Node and publishes to it periodically about the statistics from within the node
Key points:
- Requires no subscriptions, no extra copies, to do statistics on all topics
- Requires no modification to application code to use
Configuration
Set the following environment variables before launching a node to configure topic statistics
- Required:
RMW_IMPLEMENTATION_WRAPPER=rmw_stats_shim -
ROS_TOPIC_STATISTICS_WINDOW_SIZE- how many messages to use in rolling buffer for stats (stores only timestamp information, not contents data)- Default:
50
- Default:
-
ROS_TOPIC_STATISTICS_TOPIC_NAME- name of the topic to publish statistics on- Default:
/topic_statistics
- Default:
-
ROS_TOPIC_STATISTICS_PUBLISH_PERIOD- Interval in seconds at which to periodically publish stats- Default:
1.0
- Default:
Usage
colcon build --packages-select rmw_implementation rmw_stats_shim
source install/setup.bash
export RMW_IMPLEMENTATION_WRAPPER=rmw_stats_shim
# run any ROS 2 node/launch/etc

RMW Stats Shim
By using https://github.com/BonsaiRobotics/rmw_implementation, provides an implementation for RMW_IMPLEMENTATION_WRAPPER
Does the following:
- Wraps & intercepts some RMW API calls
- Calculates “published period” statistics for every Publisher
- Calculates “received period” statistics for every Subscription
- Calculates “take age” statistics for every Subscription
- This is the different between publish system timestamp and the time at which
rmw_takeis called, so is the sum of network latency plus executor latency
- This is the different between publish system timestamp and the time at which
- Creates a
/topic_statisticsPublisher for every Node and publishes to it periodically about the statistics from within the node
Key points
- Requires no subscriptions, no extra copies, to do statistics on all topics
- Requires no modification to application code to use
Configuration
Currently uses environment variables rather than Parameters system due to ease of integration.
-
ROS_TOPIC_STATISTICS_WINDOW_SIZE- how many messages to use in rolling buffer for stats (stores only timestamp information, not contents data)- Default:
50
- Default:
-
ROS_TOPIC_STATISTICS_TOPIC_NAME- name of the topic to publish statistics on- Default:
/topic_statistics
- Default:
-
ROS_TOPIC_STATISTICS_PUBLISH_PERIOD- Interval in seconds at which to periodically publish stats- Default:
1.0
- Default:
Usage
colcon build --packages-select rmw_implementation rmw_stats_shim
export RMW_IMPLEMENTATION=<whatever e.g. rmw_cyclonedds_cpp>
export RMW_IMPLEMENTATION_WRAPPER=rmw_stats_shim
# run any ROS 2 node/launch/etc
