The introduction to Diagnostics article is the place to look for general information about the files described here for Cumulus 1.

This page is only for Cumulus 1 users, please see MXdiags_folder for equivalent if you use Cumulus MX.

File type, and content

All diagnostic log files are simple text files, with multiple lines (inside a file) containing the time and a description of each event.

Entries in cumulus.~og are identified by a date (in your selected Windows locale format) and time (to milliseconds) e..g. 28/01/2017 14:29:31.083 : Reading cumulus.ini file

These latter files log many of the actions performed by Cumulus 1. They will show the Cumulus specific files that have been accessed, values found (or calculated) from log files, before and after values for updates to highs and lows for monthly and annual extreme records, rejected spikes, and much more.

File growth and deletion

A new file is created in this sub-folder each time Cumulus is restarted, after deleting the oldest and renaming the other old files to maintain the naming sequence.

Entries are added to the cumulus.~og file while Cumulus is left running, regardless of whether debugging is on or off (see example above).

To avoid loss (or inaccuracy) of readings being processed from your weather station, it is best if Cumulus is left running, and not restarted except when unavoidable. Consequently, the current diagnostic files will grow in size. If the file is left to grow too large, Cumulus will crash. Therefore, you may want to delete these files.

Any diagnostic file can be deleted at any time as Cumulus does not read from them. Cumulus creates a new file if necessary to continue its logging.

Solving Cumulus 1 Errors

The diagnostic file cumulus.~og also logs error messages, often with extra information compared to the error window (accessed by clicking error light/indicator), and that file may help you if you have a problem.

When you ask for support via the forum, you often need to upload (as a zip) one, or all, of the diagnostic files in the Diags folder especially for problems that occur when you start or restart Cumulus. Include all files in the folder, unless you definitely know that a single diags file contains all the information for both when Cumulus 1 is running normally, and when it encountered the problem and failed.

In Windows Explorer, open the Cumulus installation folder (default is C:\Cumulus). Right-click on the 'Diags' folder, and from the pop-up menu, select 'Send to -> Compressed (zipped) Folder' (available in most Windows versions). This will create a file called Diags.zip. Add debug.log from the folder above the files described on this page into the zip.

Post your message in the forum, and attach the zip file using the 'Attachment' section below the area where you have typed your message (browse for the file, then click 'Add the file').
