I get the following message in version 025
192.168.1.14 - - [10/May/2021 17:39:15] "POST /_dash-update-component HTTP/1.1" 204 -
repeated ad infinitum via standard error in the shell when I run the dash_app. Do we know what generates those messages? Thanks,
Dow

204 No Content
Server received the request, but there is no information to send back
200 level errors are not really errors but informational. 400 & 500 level are bad.
Basically,the server did what it was supposed to do.
These would normally end up in the httpd-access.log file of a web server (apache, nginx, etc). You would never see these unless you were a web server administrator perusing the logs.
Since the dash_app (index.py) is the web server, these are going into your dash logs. I would imagine the way the scripts work within plotly and friends cause these.

I've tried a couple of times to reduce the unnecessary logging information from plotly and have not been successful.

My assumption is that auto updates cause these. The update happens but there is no change in the data so the 204 is generated instead of a 200 status.

As doxidad mentioned, it's not actually an error, but if it's about reducing the log spam I've had some luck with this method from github.com/plotly/dash/issues/270. import logging
logging.getLogger('werkzeug').setLevel(logging.ERROR)This is set in dash_app/index.py just above app = dash.Dash(...)This cuts error logging down to only actual exceptions. If you still want to see non-http success codes this might not work for you. Using logging.WARNING was about the same output as logging.ERROR, or at least I didn't notice any difference just clicking through pages. Setting the level to logging.DEBUG was the default mode and shows all the request/response logs. |

Brenna,
Thank you! I'll try that change in logging level. Sound like exactly what I want as the default. This should reduce wear and tear on the SD card.

Brenna,
You ROCK! I'll add that in the base code to WeatherSense and SkyWeather2. Works like a champ.
