I have looked but didn't find similar requests, except for changes to the response time graph.

🔖 Feature description

I wouldn't say this is a change on an existing monitor per se, not tagging this request type yet, as this is more a principle feature.
Add the possibility to record the numeric values of monitors and show them in a diagram similar to the response times.

✔️ Solution

Whenever a numeric value is received in a monitor, save that value with its timestamp and the according monitor in itS own table in the DB. When the details of a monitor are opened and there are entries for this monitor in the "numeric value history table" show a graph of that numeric value simmilar to the response time graph.

Since the response time graph is limited to the same timeframe as the status bar - and it makes sense to also define the value history graph this way - additional features could be:

option to show the last day
option to show hourly average over the last week
option to show daily average over the last year
horizontal bar and red background for checks with maximum/minimum values

❓ Alternatives

No real alternatives other then using another monitoring tool that supports this, I guess...

📝 Additional Context

checking via SNMP or JSON values the history of that value may be very interesting e.g. monitor RAM of a machine and only knowing it's above the threshold I set, but not knowing whether it gradually rose to that level or suddenly spiked above it is a lack of information that may be crucial.
Since those values are already collected and compared, I guess it's "only" another table to be created/filled and visualized.
