Create thresholds response time limits for 'degraded' and 'failed'

[mxkaske]

Allow the user to select the response time limits for when a monitor is degraded and failed.

Add two new db columns for monitor:

• limitDegraded or thresholdDegraded (e.g.)
• limitFailed or thresholdFailed (e.g.)

Both should be a number that the user selects (can be via select or input). We should have a max allowed number, e.g. 45sec (45.000ms).

Right now, we have the export const monitorStatus = ["active", "error"] as const; that is used within the monitor_status and monitor schema.

We could extend it with "degraded" to include that information within a specific monitor or within a specific monitor_status (based on the region).

Within a monitor overview, extend the cards:

Right now, the displayed data is coming from Tinybird. How to calculate the 'degraded' values?

How to calculate the 'degraded' value? Multiple options:

1. extend our ping_response tb schema with a 'status' column and count the amount of different status (which will then be fixed as it will then be hardcoded in)
2. within our metrics_endpoints, pass the limit props and calculate/count the amount based on the props (dynamic, as the user could change the threshold and we will calculate them differently)

I like the second option as it is dynamic - and we don't have to extend the schema.

Open questions:

• How should we notify the users about degraded services? (again, only if >50% of regions are degraded?) We might wanna include an additional boolean db column to allow alerts?
• How to extend the Tracker class get the current status of the monitors, like "degraded" - and how to display it in the status page?
