* Use inline type hints in various other places (in `synapse/`) (#10380)Jonathan de Jong2021-07-151-3/+3

* Export jemalloc stats to prometheus when used (#9882)Erik Johnston2021-05-061-0/+1

* Limit how often GC happens by time. (#9902)Erik Johnston2021-05-051-2/+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.
* Remove redundant "coding: utf-8" lines (#9786)Jonathan de Jong2021-04-141-1/+0
| | | | | | | Part of #9744 Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now. `Signed-off-by: Jonathan de Jong <jonathan@automatia.nl>`
* Don't report anything from GaugeBucketCollector metrics until data is ↵Andrew Morgan2021-04-061-3/+13
| | | | | present (#8926) This PR modifies `GaugeBucketCollector` to only report data once it has been updated, rather than initially reporting a value of 0. Fixes zero values being reported for some metrics on startup until a background job to update the metric's value runs later.
* Fix additional type hints from Twisted upgrade. (#9518)Patrick Cloke2021-03-031-5/+6
|
* Update black, and run auto formatting over the codebase (#9381)Eric Eastwood2021-02-161-3/+4
| | | | | | | - Update black version to the latest - Run black auto formatting over the codebase - Run autoformatting according to [`docs/code_style.md `](https://github.com/matrix-org/synapse/blob/80d6dc9783aa80886a133756028984dbf8920168/docs/code_style.md) - Update `code_style.md` docs around installing black to use the correct version
* Add metrics for tracking 3PID /requestToken requests. (#8712)Erik Johnston2020-11-131-0/+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.
* Rewrite BucketCollectorRichard van der Hoff2020-09-301-47/+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?)
* Use slots in attrs classes where possible (#8296)Patrick Cloke2020-09-141-2/+2
| | | | | slots use less memory (and attribute access is faster) while slightly limiting the flexibility of the class attributes. This focuses on objects which are instantiated "often" and for short periods of time.
* Stop sub-classing object (#8249)Patrick Cloke2020-09-041-8/+8

* Add some metrics for inbound and outbound federation processing times (#7755)Erik Johnston2020-06-301-0/+6

* synapse.metrics: implement detailed memory usage reporting on PyPy (#7536)Ivan Shapovalov2020-05-221-1/+78
| | | | | | PyPy's gc.get_stats() returns an object containing detailed allocator statistics which could be beneficial to collect as metrics. Signed-off-by: Ivan Shapovalov <intelfx@intelfx.name>

* Don't disable GC when running on PyPyVincent Breitmoser2018-04-101-1/+7
| | | | | | | | PyPy's incminimark GC can't be triggered manually. From what I observed there are no obvious issues with just letting it run normally. And unlike CPython, it actually returns unused RAM to the system. Signed-off-by: Vincent Breitmoser <look@my.amazin.horse>
* Add a metric which increments when a request is receivedRichard van der Hoff2018-03-091-0/+16
| | | | | | It's useful to know when there are peaks in incoming requests - which isn't quite the same as there being peaks in outgoing responses, due to the time taken to handle requests.

* | Change CacheMetrics to be quickerErik Johnston2016-06-031-10/+6
|/ | | | | | We change it so that each cache has an individual CacheMetric, instead of having one global CacheMetric. This means that when a cache tries to increment a counter it does not need to go through so many indirections.
