* Remove support for Python 3.7 (#15851)Eric Eastwood2023-07-051-8/+2
| | | Fix https://github.com/matrix-org/synapse/issues/15836
* Add missing type hints to tests. (#14687)Patrick Cloke2022-12-281-8/+16
| | | Adds type hints to tests.metrics and tests.crypto.

* Escape label values in prometheus metricsErik Johnston2018-05-021-1/+20

* report metrics on number of cache evictionsRichard van der Hoff2018-02-051-0/+12
|
* Change CacheMetrics to be quickerErik Johnston2016-06-031-13/+10
| | | | | | 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.

* Add an .inc_by() method to CounterMetric; implement DistributionMetric a ↵Paul "LeoNerd" Evans2015-03-121-3/+2
| | | | neater way
* Rename TimerMetric to DistributionMetric; as it could count more than just timePaul "LeoNerd" Evans2015-03-121-12/+12
|
* Export CacheMetric as hits+total, rather than hits+misses, as it's easier to ↵Paul "LeoNerd" Evans2015-03-121-3/+3
| | | | derive hit ratio from that
* Prometheus needs "escaped" label valuesPaul "LeoNerd" Evans2015-03-121-27/+27

* Bugfix to rendering output of vectored TimerMetricsPaul "LeoNerd" Evans2015-03-121-4/+4

* Rename Metrics' "keys" to "labels"Paul "LeoNerd" Evans2015-03-121-3/+3

* Initial hack at a TimerMetric; for storing counts + duration accumulatorsPaul "LeoNerd" Evans2015-03-121-1/+35
|
* Implement vector CallbackMetricsPaul "LeoNerd" Evans2015-03-121-1/+17
|
* Rename CacheCounterMetric to just CacheMetric; add a CallbackMetric ↵Paul "LeoNerd" Evans2015-03-121-9/+15
| | | | component to give the size of the cache
* Initial attempt at a scalar callback-based metric to give instantaneous ↵Paul "LeoNerd" Evans2015-03-121-1/+21

* Create the concept of a cachecounter metric; generating two counters ↵Paul "LeoNerd" Evans2015-03-121-1/+26
| | | | specific to caches
* Initial tiny attempt at (vectorable) counter metricsPaul "LeoNerd" Evans2015-03-122-0/+61
