Sunday fun: analysing log data and comparing the logs of an #IoT device with the backend service’s.

We have a discrepancy in what the device sees and what our web interface shows, so we need to figure out where the data loss happens. Unfortunately IoT devices are simple and minimise the data because of storage limits. So it’s not an easy task to analyse them.

For example: each line contains one log entry with all the meta data we can get. So the format uses a lot of abbreviations and codes to fit everything. Also the time stamp of each entry is relative, not absolute. That means I get the time since the device is running in seconds instead of a Unix time stamp or ISO date time string.

Do you work with IoT devices? What are your experiences?
