Loading full home assistant log crashes/freezes browser.

The problem

Home assistant log file is 609,000 lines long of content. Clicking load full log literally freezes and then crashes safari. On Chrome it freezes for a while and then loads but scrolling causes issues with rendering the text (page is empty when I scroll).

Expected behavior

My browser shouldn't crash, perhaps the log file needs to be truncated and/or buffered.

Steps to reproduce

1. Create a home-assistant.log file with 600k+ (perferrably a million lines of text). If I had to guess each line of the logs is about 125 characters.
2. Open the logs section
3. Click Load full home assistant log file.

Environment

• Home Assistant release with the issue: 118.5
• Last working Home Assistant release (if known):
• Browser and browser version: Safari 14.0.1 / Chrome 85 latest
• Operating system: Big Sur 11.0.1

How do you end up with a such a massive log? Do you have very verbose log / debug settings?

I am not really sure if that is actually relevant production use case then.

I had my log level set to info, but there must have been an update to HomeKit lately because a large percentage of it was HomeKit getting characteristics. I have tons of integrations and entities. Regardless it's impossible to know what production levels are but I'd say this is production. The longer and more stable ha is the bigger the log file will be

[spacegaier]

I am not sure if log level "info" is really production if there is a bunch of technical data stored in the log (I assume that is what those mentioned characteristics are).

You might consider rotating the log files, e.g.: hass --log-rotate-days 4

To really handle huge logs in the frontend we would probably need to paginate the rendering.
