Couple of notes

[chipironcin]

Cool project! Thanks for sharing with all of us :)

I played with it a little bit and found the following limitations:

• No shared crosshair
• Only latency is stored in the database (no failed pings)
• No minimum interval (should be the interval of pings)
• Not sure if Grafana/Influx are estimating values due to lack of space when selecting a big time window. Maybe we need a "max" function here and there

Also I tried adding the following panels

• How many pings over/under x ms
• Percentage of time latency was over/under x ms

But found them not super reliable due to my questions/observations on the first paragraph.
If someone could help me clarify these I could contribute the panels with more confidence 👍

(Here is what I have so far, for those who want to play with it. Keep in mind it can be wrong and it is unfinished)
