Viewing logs via Goliothctl​

After sending a log entry to Golioth you can search logs using goliothctl logs. Here is an example showing logs from the last 10 minutes:

$ goliothctl logs --interval 10m
[2022-05-04T18:52:36Z] level:DEBUG  module:"golioth_hello"  message:"Start Hello sample"  device_id:"623a1a9d3023c546c6b19c99" metadata:"{"func":"main","index":1,"uptime":68349792}"

You can also filter the logs by Zephyr module. This could be a Golioth module, a Zephyr subsystem or your application. You can see the module names are being reported in the output above. This example filters for the messages sent by the golioth_system module:

$ goliothctl logs --interval 1h --module golioth_system
[2022-05-04T18:52:36Z] level:INFO  module:"golioth_system"  message:"Starting connect"  device_id:"623a1a9d3023c546c6b19c99" metadata:"{"index":4,"uptime":68350433}"
[2022-05-04T18:52:36Z] level:INFO  module:"golioth_system"  message:"Client connected!"  device_id:"623a1a9d3023c546c6b19c99" metadata:"{"index":5,"uptime":68682373}"

You can check for more commands to search logs on the goliothctl logs reference docs.
