Hello, I run 123solar on a raspberry 2 Mod. B with nginx and php-fpm.

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
634 www-data 20 0 7768 5900 4748 S 18.1 0.6 0:09.89 nginx

In the nginx log I every secound somethink like: [09/Jun/2023:11:30:01 +0200] "GET /solar/programs/programlive.php?invtnum=1 HTTP/1.0"

Why does it poll so often? what is it for? and how can i do it more efficient?

Best regards

To show 'live' data you need to retrieve them.. If you don't show 123s pages, there is no programlive requests

Thanks for the fast answer. Where can I set the interval? Whats about websockets to do this?

line 387 I won't change the index behavior, you can set pooling in dashboard. If you find a better way to improve perf, tell me how

jeanmarc77 commented 1 year ago

also set access_log off; in nginx.conf will improve your system perf
