Re: [tor-relays] How to reduce tor CPU load on a single bridge?



Gary C. New via tor-relays:
Georg,
Yes! That is precisely it!
Please know that the change appears to be working with my loadbalanced Tor Relay deployment as well.
Are there any "Issues" submitted for a similar change to Concensus Weight and Relay Probability to Tor Metrics on Onionoo? It appears these values are still only being reported for a Single Tor Node.

Hrm, good question. I don't think so and I am not sure yet, whether we should make such a change.

A BIG Thank You to the Tor Metrics Team for the Issue-40022 implementation.

You are welcome. It seems, though, the implementation was not correct. We therefore reverted it for now. However, we are on it. :)

David,
Has Tor Metrics implemented your RFC related to Written Bytes per Second and Read Bytes per Second on Onionoo?

That's probably

, no?

As of the 27th of February, I've noticed a change in reporting that accurately reflects the aggregate of my Tor Relay Nodes opposed to the previously reported Single Tor Node. Are you seeing a similar change for snowflake.torproject.org?
Additionally, other than the hourly stacktrace errors in the syslog, the secure_onion_key workaround seems to be working well without any ill side-effects. I've been able to operate with the same secure_onion_key for close to 5 weeks, now. Have you run into any issues?
Thank you for your response.

  David,
Excellent Documentation and References!
I hope the proposed RFC's (auth, key, and metrics) for loadbalanced Tor topologies are seriously considered and implemented by Tor Core and Tor Metrics.
Great Work!

Observations since:

Metrics graphs are currently confused by multiple instances of tor
uploading descriptors under the same fingerprint. Particularly in the
interval between 2022-01-25 and 2022-02-03, when a production bridge and
staging bridge were running in parallel, with four instances being used
and another four being mostly unused.

Since 2022-02-03, it appears that Metrics is showing only one of the
four running instances per day. Because all four instances are about
equally used (as if load balanced, go figure), the values on the graph
are 1/4 what they should be. The reported bandwidth of 5 MB/s is
actually 20 MB/s, and the 2500 clients are actually 10000. All the
necessary data are present in Collector, it's just a question of data
processing. I opened an issue for the Metrics graphs, where you can also
see some manually made graphs that are closer to the true values.

I started a thread on tor-dev about the issues of onion key rotation and
ExtORPort authentication.
