Monthly log files: Difference between revisions

This article is about the log file that contains the values at whatever interval you have set for Cumulus to keep detailed logging. The main files are automatically created with names in the form <Month><Year>log.txt (for example, the file for August 2009 is often called <tt>Aug09log.txt</tt>), but the month can be in another language or a different abbreviation depending on your locale; an entry is made to the current month's file every ''ten'' (default value; you can change this on the station settings screen) minutes, recording the current sensor values. The file is in comma-separated format with one line per entry. Being comma separated does not mean the fields in this log are always separated by commas, they might use semi-colon (;) for example.

There is an equivalent log file for [[Extra_Sensor_Files|extra sensor]] values.  In fact, in Cumulus MX, the processing of this extra sensor logging file shares a lot of the code with the processing of the standard logging file, as they both are updated at same interval, and they both take values processed following a read from your weather station. The applications programming interface (api) that sends values between the MX engine and the MX admin interface is also identical (with a parameter "Extra" that swaps between true and false depending on the log file involved).

See [[speciallog.txt]] for the equivalent log file for detailed logging of internal temperature and humidity, but it is not split into separate files for each month.  Although this exists in Cumulus 1, it appears this functionality is missing from MX.
