logging tools for ros

Installation

You need to have a base ROS installation as well as the warehousewg stack installed. Then, clone this repo into your ROS_PACKAGE_PATH and do a make.

Setup

The simplest way to run the logging nodes is:

$ roslaunch logging_tools ros_logging.launch run_db:=true db_path:=/path/to/db

You can leave out db_path, in which case it will default to /tmp/mongo. If you're already running a Mongo db server for other purposes (on port 27017), use run_db:=false instead.

Usage

Querying rosout

Use the grep_log tool, e.g., if you want to find out when exactly your robot caught fire:

$ rosrun logging_tools grep_log -m fire

For general help, see:

$ rosrun logging_tools grep_log -h

If you use this often, you can add an alias to your .bashrc:

alias gl="rosrun logging_tools grep_log"

Querying the action history

For each ROS action that was performed, the goal message, goal time, and result time and status are logged. You can query by specifying action name and optionally a max and min age. E.g., the following gets all move_base actions that happened between one and two hours ago:

$ rosrun logging_tools search_actions -x 120 -m 60 -a move_base
