Debug.log
The debug logging feature is extremely useful in troubleshooting problems with Cumulus and/or connectivity to your weather station or FTP upload communications.
By default this is not enabled, but can be turned on and off as required. Click on the Settings / Program settings menu within CumulusMX (Settings / Station settings menu in Cumulus 1) and tick the 'Debug Logging' menu option.
The file contains a wealth of data including the raw data received from your weather station, connectivity attempts, file uploads, etc.
Note: Logging is turned on when you 'Save' the chnage in settings. It is automatically turned off if Cumulus is restarted. The file can grow very large very quickly so turn the Debug Log option off it not required. If the file grows too large it can cause Cumulus to crash.
File Location, Name and Format
In Cumulus 1, the file is called Debug.log, and is located in the root of the Cumulus folder.
In CumulusMX, debug logging adds additional detail into the standard logging file. This is located in folder MXdiags within the CumulusMX root directory. It is a text (*.txt) file named by the date and time that the CumulusMX session began, for example: 20210112-171450.txt
The log file is a simple text file containing the time and a description of each event.
The file can be deleted at any time as Cumulus does not read from it.
