[X] My Assistant

My H@H had a blackout due to the hard drive failure (strange thing that H@H didn't give neither IO errors nor warnings)
I fixed that, and reenabled it, seeing a trust of 300 and the quality of 2k
The strange part is that my quality is now decreasing, though trust goes up as normal

Is there a timeout for it's growth?

EDIT: restarted it one more time, quality began to raise as normal

Quality is calculated by comparing your average failure rate with your average hit rate - meaning it's largely independent of raw speed - together with some additional conditions if trust is low. This gets averaged over a long period of time, with the actual fractional gain or loss depending on whether the current quality is higher or lower than the averaged quality. (Basically, you drop quality much faster than you gain it, to avoid an oscillating load effect.)

~6000 is slightly lower than the average quality (currently ~6800), which means you probably had a period of many files being dropped. If there weren't any network interruptions, the client probably had a period of being overloaded in some way.

Would you add the average quality on the H@H status page later? (IMG:[invalid] style_emoticons/default/smile.gif)

Thanks for the explanations. I guess the "immediate" failure rate is directly linked to the trust value, right ?

That's what I thought, but none of these issues seems to have happened.
Anyway, my client utilization is slowly going back to normal, so yeah, maybe it was a coincidence that it faced issues the same day the new system had been set up.

@Hairs Fan: Where can I get these fancy graphs? I need moar stats (IMG:[invalid] style_emoticons/default/smile.gif)

I use collectd+drraw to generate mines, which probably implies to have a Linux/Unix system.

Thanks for the tip, as I had problems running GUI H@H under Ubuntu and had no stats available

What about disconnections? Connection errors due to peers don't seem to cause trouble for trust, but do they affect quality?

To some extent. Trust tanks if you fail client-to-client tests, as well as if your client has a very high failure rate. But unlike quality, trust is mostly treated as a binary trusted/untrusted condition, so it doesn't directly affect how traffic is prioritized.

You're taking about those random "connection interrupted or closed by remote host" messages that pop up from time to time? It depends, but mostly those are people who don't wait for the image to fully load before jumping on to the next one, and in those cases it wouldn't affect it.

Those are more than likely due to temporary network issues on your or your ISP's end.

My network service is three pairs of redundant 10GB fibre links out to Comcast, Cogent, Level 3 and a couple of others, with backup through Big APE; plus several direct connections to the Internet 2 backbone, with backup through Harvard NOX. I'm reasonably confident that my H@H trust issues haven't been ISP glitches.

Multi-homing with BGP can still fail. I didn't get to your logs early enough to say anything for sure, but it might have been the same issue as the guy in this thread. Let me know if there are further problems.

BGP can fail. It's very unlikely to fail outright given the network that I'm on. Look up my H@H client IP address and then PM me if you'd care to discuss in more detail.

Waiting for my 1 GBPS Monster to be set up.
Lets see if this grants me a perma 10000 (IMG:[invalid] style_emoticons/default/tongue.gif)

How much does that server run you, Ichy?

Dunno. Still waiting for it to set up. Germans are lazy bastards and wont do shit at night (IMG:[invalid] style_emoticons/default/dry.gif)

Wow really?

it might have been the same issue as the guy in this thread.

I think have something like that, only for Quality metric now
I checked on stats just a minute ago and saw 3k quality together with 1k Trust.
I'd thought that "My ISP broke something" but as I refreshed the stats, Quality was building itself back up at a pretty high rate.
Then, half an hour later it began to drop back
It is stabilized near 3.5k, which doesn't make any sense, and my H@H now never gets upload speed over 300KB/s because of this
I'm also getting my max speed at 3/4 of maximum burst, which doesn't make any sense neither, as H@H speedtests show the full speed

Well no, quality works fundamentally differently by measuring the actual failure rate of your client. And because the system has user-specific exclusion lists for H@H clients that don't appear to be reachable for that specific user, a quality drop is a very strong indication of a connectivity, routing or performance problem of some kind.

Oh, disregard everything I posted here, seems like Quality is more reliable than I thought

My Dlink went haywire with it's QoS engine, causing all the strange things lately
Turned it off and both the measured speeds and latencies came to normal
BTW, still [i.imgur.com] I don't think there should be so much http 400 errors

It seems everyones Score has decreased by a lot. Even mighty G just Gs Score has suffered.

My clients do not get good quality (IMG:[invalid] style_emoticons/default/cry.gif)

Yeah, I noticed. However I'm glad that my own score has stayed pretty much the same as usual, or perhaps even gotten a bit higher. Don't know if it's because my quality has stayed a constant 10K?

My other client has a tendency to crash every week or two, so we'll see how much those will drop my score in the future.

Don't think that's severe enough to have the score halfed... and given that he uses 10Gbps servers for H@H and achieving 80MB/s for each slot, those should always be at 10000 quality. Perhaps he just got some servers down.

My Client was: Last seen: 1970-01-01 00:00 (IMG:[invalid] style_emoticons/default/laugh.gif)
So I had a Client running when Tenbs Dad was still Admin here.

/edit: now lets see if my 1 GBPS Monster does any good. If yes I probably kill off some of my shitty boxes and get more fast ones (IMG:[invalid] style_emoticons/default/tongue.gif)
