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.

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.

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"

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
