Is there a parameter to keep cumulus from writing to wxnow?

[visuel]

Hi all,

At the wiki I read:

Code: Select all

"The wxnow.txt file is created by Cumulus if you elect to generate and upload data to the APRS network."

Although I do not want to upload to the APRS network, cumulus.exe still writes every 10 seconds to the wxnow.txt file in the installation directory.

I use version 1.9.1 and the APRS/CWOP settings (not enabled) are empty in the Internet settings dialog.

Is there a parameter to keep cumulus.exe from writing to wxnow.txt.

The wiki was incorrect (I've amended it). Cumulus always recreates the wxnow.txt file once a minute (not every 10 seconds) and there is no option to disable this. Is it causing you a problem?

Thanks.
My mistake, I thought cumulus was writing to this file every 10 seconds.

It is not causing any problem, except that cumulus.exe is doing (reading and/or writing) something every 10 seconds with my harddisk. It is keeping the disk form falling to sleep, that is all.

Since I am logging only once every hour I was wondering what happens every 10 seconds and then I only found the wxnow.txt file that had a recent timestamp.

Cumulus will write to the disk quite frequently just after it starts, but after a few minutes I can't think of anything that would cause it to write anything at less than one minute intervals (unless you were using realtime uploads etc, of course).

At the main window at the bottom at the right, you see "Last data read at: 14:29:50" for example.

This changes every ten seconds.

Every time cumulus reads the data (from the weather station?) it reads or writes my harddisk at that exact moment as well.

Maybe it reads the data from a buffered driver file?

[steve]

If the reading means that a high or low is exceeded (for today, for example) then a disk write will occur. I can't think of any other reason for a disk write when the data is read.

I've put an ini-file option in the next build to turn off creating wxnow.txt, by the way.

I think you are right!

I supose it has something to do with the very bad weather currently here in the Netherlands.


With Procmon from sysinternals I was able to see it was writing a lot (almost every ten seconds) to the today.ini file.
After a while cumulus.exe only wrote to the wxnow.txt once per minute and did something on the debug.log file:

Thanks for the extra option in the ini.file!

Maybe you can have a look at the debug.log, since I did not have the debug option on and still cumulus.exe is doing something on the debug.log as you can see in the log above.

Regards,

Victor

The debug log is beyond my control, I'm afraid. It's not supposed to do anything with the file when it's turned off, and it would require large-scale changes to Cumulus to use something else.

Ok, I understand.

Thanks anyway.
