Using Logging Functionalities

Configuring the Logging Settings

The logging configuration of the Open Edge Device Kit is defined in the settings file /ipc/cfg/oedk_config.json. The following table lists the configurable logging parameters:

Parameter Description
active_log_directory directory for active log files
upload_log_directory directory for uploading log files
archived_log_directory directory for archiving log files
size_mb size limit for log files

The following extract of the Open Edge Device Kit shows an example logging configuration:

        "archived_log_directory": "/persistent_massdata/tmp/archive/",

        "log_history_days": 8,
        "upload_cycle_sec": 120
    }

Automatic Log File Archiving

The Open Edge Device Kit regularly creates new log files and archives the previous file. This is triggered if either of the following conditions is fulfilled:

  • Time: The Open Edge Device Kit creates a new log file when the first log message of a new day arrives.
  • Size: The Open Edge Device Kit creates a new log file when the current file reaches the user defined size limit size_mb.

Log File Upload

The Open Edge Device Kit automatically copies archived log files into the upload folder and starts the upload.
