Hello all

I was wondering how the calculation of the Health Score is done and I found some things in the code, now the question is why I am missing e.g. 10 points.
There are apparently a few possibilities therefore my question: Would it be possible to make the whole thing more transparent so that you see why the points are missing and you can do something about it if necessary?

I explained in natural language how the scoring works in a Friendica forum post I'd be hard-pressed to find again, but the gist is that scoring is dependent of over time effects to limit score drops in case of rare temporary outages.

The scoring was almost entirely lifted from the previous version of the directory that I didn't write, and adding a detailed breakdown would be a significant undertaking I'm not planning on taking on anytime soon.

You should check your score in a week or so to see if it changed or not. Most important criterions are: HTTPS, Friendica code version, server availability, request time. The latter is unfortunately depending on the location of the directory in France, but you shouldn't be unfairly penalized for this in Germany.

Thanks again for the explanation, yes I have already discovered a few points in the code but I do not think that everyone understands php hence my intention for the issue

Maybe you could just put this in as a kind of information page, it doesn't have to be programmed.

Found it!

Here's the breakdown of the scoring:

Min health: -100.

Default max health: 100.

New server: 50.

Probe status: Success +10, Failure -30.

Request time score: <120ms +10, 120-250ms +5, 250-400ms 0, 400-800ms -5 (max health 60), >800ms -10 (max health 40).

SSL status: disabled -10, enabled +10.

Friendica version: stable 0, RC/dev max health 95, less than stable -10 above 0 health, 3 or less max health 30.

New Server(50) + Probe(10) + time(10) + ssl(10) = 80
isn't that 20 points missing? so if i assume the best case

True, but your node on its new location was found before by the directory, so it's possible you got 10 additional points from my manual poll earlier.

then thank you for the 10 points ;)
I think that with repeated positive tests the score continues to rise?

It will, until it reaches 100, the current maximum.

It would be nice to add info on mouse over for health scores below 100. Probably a lot of work and unsure if it is worth the effort, but from a users perspective it is helpful to learn why the score is not 100 for a specific instance.

Some time ago, I had the idea of adding a server details page that could list the probing history and explicit what came into the health score but it’s a sizable endeavor, not least because we don’t currently save why the score changes on any given probe.
