2024-01-30metrics: Add new relay metrics to MetricsPortDavid Goulet
This commit adds the total number of DROP cell seen, the total number of DESTROY cell received and the total number of protocol violation that lead to a circuit close. Closes #40816 Signed-off-by: David Goulet <dgoulet@torproject.org>

2022-03-15rephist: Introduce a fraction and period for overload onionskinDavid Goulet
This code was heavily reused from the previous DNS timeout work done in ticket #40491 that was removed afterall from our code. Closes #40560 Signed-off-by: David Goulet <dgoulet@torproject.org>
2022-02-22Handle other places that use onion handshake type valuesMike Perry
We want ntor and ntorv3 to use the same queues and stats.
2021-12-13relay: Change DNS timeout label on MetricsPortDavid Goulet
Change it from "timeout" to "tor_timeout" in order to indicate that the DNS timeout is one from tor's DNS threshold and not the DNS server itself. Fixes #40527 Signed-off-by: David Goulet <dgoulet@torproject.org>
2021-10-20relay: Overload state on DNS timeout is now X% over Y secsDavid Goulet
With this commit, we will only report a general overload state if we've seen more than X% of DNS timeout errors over Y seconds. Previous behavior was to report when a single timeout occured which is really too small of a threshold. The value X is a consensus parameters called "overload_dns_timeout_scale_percent" which is a scaled percentage (factor of 1000) so we can represent decimal points for X like 0.5% for instance. Its default is 1000 which ends up being 1%. The value Y is a consensus parameters called "overload_dns_timeout_period_secs" which is the time period for which will gather DNS errors and once over, we assess if that X% has been reached ultimately triggering a general overload signal. Closes #40491 Signed-off-by: David Goulet <dgoulet@torproject.org>
2021-05-12rephist: Add a counter for the onioniskins statsDavid Goulet
Current counters are reset every heartbeat. This commit adds two counters for the assigned and dropped onionskins that are not reset so they can be exported onto the MetricsPort. Closes #40387 Signed-off-by: David Goulet <dgoulet@torproject.org>
2021-05-12relay: Add TCP port exhaustion metricsDavid Goulet
Signed-off-by: David Goulet <dgoulet@torproject.org>
2021-05-12dns: Gather DNS request statisticsDavid Goulet
We now keep track of all errors and total number of request seen. This is so we can expose those values to the MetricsPort to help Exit operators monitor the DNS requests and failures. Related to #40367. Signed-off-by: David Goulet <dgoulet@torproject.org>
2021-05-12relay: Add the global connection limit metricsDavid Goulet
This emits two events (read and write) of the total number that the global connection limit was reached. Related to #40367 Signed-off-by: David Goulet <dgoulet@torproject.org>
2021-05-12relay: Add the onionskins processing metricsDavid Goulet
With this commit, a relay now emits metrics event on the MetricsPort related to how many onionskins were handled (processed or dropped) for each handshake type. Related to #40367 Signed-off-by: David Goulet <dgoulet@torproject.org>

2021-02-19hs: Remove v2 statsDavid Goulet
We still keep v2 rendezvous stats since we will allow them until the network has entirely phased out. Related to #40266 Signed-off-by: David Goulet <dgoulet@torproject.org>

2020-07-10Split bidi connection-stats code into a new C file.Nick Mathewson
2020-07-10Split bandwidth history functions into a separate C file.Nick Mathewson
These are logically independent from the rest of rephist, and make more sense in isolation. The next patch will rename them too.

2018-09-27Move the predicted ports code out of rephist.cNick Mathewson
It differs from the rest of the rephist code in that it's actually necessary for Tor to operate, so it should probably go somewhere else. I'm not sure where yet, so I'll leave it in the same directory, but give it its own file.

2018-07-05Move literally everything out of src/orNick Mathewson
This commit won't build yet -- it just puts everything in a slightly more logical place. The reasoning here is that "src/core" will hold the stuff that every (or nearly every) tor instance will need in order to do onion routing. Other features (including some necessary ones) will live in "src/feature". The "src/app" directory will hold the stuff needed to have Tor be an application you can actually run. This commit DOES NOT refactor the former contents of src/or into a logical set of acyclic libraries, or change any code at all. That will have to come in the future. We will continue to move things around and split them in the future, but I hope this lays a reasonable groundwork for doing so.
