Custom data support

[pitbox46]

This is a work in progress!

Description

Adds support for arbitrary numeric data in the form of "extra data" (eData). The functionality is as follows

1. Store the extra data in system_stats.stats.eData as a key-value pair. This is easily done by watching for new records and updating them.
2. Create a record under the extra_data_configs collection. Each record is 1 chart for 1 system. Depending on the parameters, we can display several different extra variables on the chart.

We can utilize the Pocketbase API to add what we want using a separate process. This way, minimal changes have to be made to Beszel's code and the system is easily modifiable.

Battery Charge Example

beszel_bat.mjs

(I have the laptop to keep the battery at ~80%, so I expect the graph to be flat)

Todo

• Implement the extra_data_configs collection in Beszel (unsure how how to do this)
• Add example battery charge example
• Documentation

Interesting idea, thanks. I'll think it over and try to get back to you tomorrow but it may be a few days.

I'm not sure of how to add the container extra_data_configs via the agent (I'm not very familiar with go), so I had to implement it using my JS script for now. You can see my script here beszel_bat.mjs.

I will also update the description with some new info and an example image.

Sorry, forgot about this and it was closed automatically. I'll reopen and try to get to it relatively soon but I'm absolutely slammed at the moment :-/
