What debugging/monitoring method do you use? Lately, I have been using the Saleae Logic Analyzer to monitor the signals exchanged among the boards of my embedded network. I find it really cool, but do you have any other recommendations? What do you use?

• mpacklog.py

  1 6 8.4 Python

  Log dictionaries to MessagePack files in Python

  

In robotics most relevant signals are seen by the software. My current pattern is to log everything to MessagePack files (e.g. using mpacklog in Python or palimpsest in C++), then dump and plot the data later on using handy command-line tools like jq and rq.

• palimpsest

  1 10 8.2 C++

  Fast serializable C++ dictionaries

• InfluxDB

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• jq

  306 25,063 0.0 C

  Discontinued Command-line JSON processor [Moved to: https://github.com/jqlang/jq] (by stedolan)

  Record Query - A tool for doing record analysis and transformation (by dflemstr)

• PlotJuggler

  9 4,080 9.1 C++

  The Time Series Visualization Tool that you deserve.

If you use ROS, you will have similar facilities with ROS bags and e.g. PlotJuggler. ROS bags are not as convenient to manipulate as MessagePack/JSON dictionaries, although they hold similar data, because the ecosystem is smaller (i.e. less people manipulating them and developing tools to manipulate them more efficiently).

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
