Federation Lag-o-meter (aftershock.lemmy.management)

I made this based on the gripe about some of the silent failures with federation. Might help users choose other servers. Might help admins troubleshoot. Open to comments and criticisms!

Oooohhh ... Nice!! I'm repeatedly impressed at how many hackers are going ahead and just getting some stuff done here!!

Questions/thoughts:

What instance is used as a reference for the delay? One you self-host (lemmy.management)?
Sooo ... what's the deal with lemmy.ml ... that seems to have gone beyond lag and is basically falling over ... seems like the devs have neglected their own instance's health?
What's that Redash? Is it a plotly thing or some other product that just uses their graphing library? How have you found it?

What instance is used as a reference for the delay? One you self-host (lemmy.management)?

Yes. lemmy.management. It is purposefully updating subscribed communities to as many as possible (via automation.) This doesn't correct for network lag, but the idea was to capture the "federation" lag. There's no code I'm aware of that allows admins to prioritize outbound federation traffic. I could be wrong though.

Sooo … what’s the deal with lemmy.ml … that seems to have gone beyond lag and is basically falling over … seems like the devs have neglected their own instance’s health?

I just collect the data.

What’s that Redash? Is it a plotly thing or some other product that just uses their graphing library? How have you found it?

https://redash.io I don't remember how I found it. Probably an "awesome" list on github.
