Diags folder
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.
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').
