* | Fix logging context warnings due to common usage metrics setup (#14574) | Sean Quah | 2022-11-28 | 1 | -1/+3 |
| | | | | | | | | | `setup()` is run under the sentinel context manager, so we wrap the initial update in a background process. Before this change, Synapse would log two warnings on startup: Starting db txn 'count_daily_users' from sentinel context Starting db connection from sentinel context: metrics will be lost Signed-off-by: Sean Quah <seanq@matrix.org> | ||||

* | Fix mypy for platforms without epoll support. (#11771) | Patrick Cloke | 2022-01-19 | 1 | -2/+2 |

* | Improve `reactor_tick_time` metric (#11724) | Richard van der Hoff | 2022-01-17 | 2 | -93/+84 |
| | | | | | | | | | | | 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. | ||||
* | Simplify GC prometheus metrics (#11723) | Richard van der Hoff | 2022-01-13 | 2 | -159/+206 |
| | | | | | Rather than hooking into the reactor loop, just add a timed task that runs every 100 ms to do the garbage collection. Part 1 of a quest to simplify the reactor monkey-patching. | ||||

| | | | | | | | | | | | | | | | | | | | * Teach MyPy that the sentinel context is False This means that if `ctx: LoggingContextOrSentinel` then `bool(ctx)` narrows us to `ctx:LoggingContext`, which is a really neat find! * Annotate RequestMetrics - Raise errors for sentry if we use the sentinel context - Ensure we don't raise an error and carry on, but not recording stats - Include stack trace in the error case to lower Sean's blood pressure * Make mypy pass for synapse.http.request_metrics * Make synapse.http.connectproxyclient pass mypy Co-authored-by: reivilibre <oliverw@matrix.org> | ||||
* | Relax `ignore-missing-imports` for modules that have stubs now and update ↵ | David Robertson | 2021-10-08 | 1 | -1/+1 |
| | | | | | | | | | | | | mypy (#11006) Updating mypy past version 0.9 means that third-party stubs are no-longer distributed with typeshed. See http://mypy-lang.blogspot.com/2021/06/mypy-0900-released.html for details. We therefore pull in stub packages in setup.py Additionally, some modules that we were previously ignoring import failures for now have stubs. So let's use them. The rest of this change consists of fixups to make the newer mypy + stubs pass CI. Co-authored-by: Patrick Cloke <clokep@users.noreply.github.com> | ||||

* | Limit how often GC happens by time. (#9902) | Erik Johnston | 2021-05-05 | 1 | -2/+16 |
| | | | | | | | | | | | | | | | Synapse can be quite memory intensive, and unless care is taken to tune the GC thresholds it can end up thrashing, causing noticable performance problems for large servers. We fix this by limiting how often we GC a given generation, regardless of current counts/thresholds. This does not help with the reverse problem where the thresholds are set too high, but that should only happen in situations where they've been manually configured. Adds a `gc_min_seconds_between` config option to override the defaults. Fixes #9890. | ||||

| * | Always use the name as the log ID. (#9829) | Patrick Cloke | 2021-04-20 | 1 | -11/+4 |
| | | | | | | | | | | As far as I can tell our logging contexts are meant to log the request ID, or sometimes the request ID followed by a suffix (this is generally stored in the name field of LoggingContext). There's also code to log the name@memory location, but I'm not sure this is ever used. This simplifies the code paths to require every logging context to have a name and use that in logging. For sub-contexts (created via nested_logging_contexts, defer_to_threadpool, Measure) we use the current context's str (which becomes their name or the string "sentinel") and then potentially modify that (e.g. add a suffix). | ||||

* | Add metrics for tracking 3PID /requestToken requests. (#8712) | Erik Johnston | 2020-11-13 | 1 | -0/+10 |
| | | | | | | The main use case is to see how many requests are being made, and how many are second/third/etc attempts. If there are large number of retries then that likely indicates a delivery problem. | ||||
* | Start fewer opentracing spans (#8640) | Erik Johnston | 2020-10-26 | 1 | -3/+9 |
| | | | | | | | #8567 started a span for every background process. This is good as it means all Synapse code that gets run should be in a span (unless in the sentinel logging context), but it means we generate about 15x the number of spans as we did previously. This PR attempts to reduce that number by a) not starting one for send commands to Redis, and b) deferring starting background processes until after we're sure they're necessary. I don't really know how much this will help. | ||||

* | Rewrite BucketCollector | Richard van der Hoff | 2020-09-30 | 1 | -47/+68 |
| | | | | | | | | | | | | This was a bit unweildy for what I wanted: in particular, I wanted to assign each measurement straight into a bucket, rather than storing an intermediate Counter which didn't do any bucketing at all. I've replaced it with something that is hopefully a bit easier to use. (I'm not entirely sure what the difference between a HistogramMetricFamily and a GaugeHistogramMetricFamily is, but given our counters can go down as well as up the latter *sounds* more accurate?) | ||||

| | | | | | | | | | | | | | | | | This introduces a mechanism for tracking resource usage by background processes, along with an example of how it will be used. This will help address #3518, but more importantly will give us better insights into things which are happening but not being shown up by the request metrics. We *could* do this with Measure blocks, but: - I think having them pulled out as a completely separate metric class will make it easier to distinguish top-level processes from those which are nested. - I want to be able to report on in-flight background processes, and I don't think we want to do this for *all* Measure blocks. | ||||
