* Improve `reactor_tick_time` metric (#11724)Richard van der Hoff2022-01-171-16/+0
| | | | | | | | | | | The existing implementation of the `python_twisted_reactor_tick_time` metric is pretty useless, because it *only* measures the time taken to execute timed calls and callbacks from threads. That neglects everything that happens off the back of I/O, which is obviously quite a lot for us. To improve this, I've hooked into a different place in the reactor - in particular, where it calls `epoll`. That call is the only place it should wait for something to happen - the rest of the loop *should* be quick. I've also removed `python_twisted_reactor_pending_calls`, because I don't believe anyone ever looks at it, and it's a nuisance to populate.

* Add missing prometheus rules for persisted events (#8802)Johanna Dorothea Reichmann2020-12-021-0/+18
| | | | | | | The official dashboard uses data from these rules, but they were never added to the synapse-v2.rules. They are mentioned in this issue: https://github.com/matrix-org/synapse/issues/7917#issuecomment-661330409, but never got added to the rules. Adding them results in all graphs in the "Event persist rate" section to function as intended. Signed-off-by: Johanna Dorothea Reichmann <transcaffeine@finallycoffee.eu>
