* Replace the @metrics.counted annotations in federation with ↵Paul "LeoNerd" Evans2015-03-121-17/+0
| | | | specifically-written counters and distributions
* Add an .inc_by() method to CounterMetric; implement DistributionMetric a ↵Paul "LeoNerd" Evans2015-03-121-23/+14
| | | | neater way
* Don't forbid '_' in metric basenames any more, to allow things like foo_timePaul "LeoNerd" Evans2015-03-121-5/+0
|
* Rename TimerMetric to DistributionMetric; as it could count more than just timePaul "LeoNerd" Evans2015-03-122-14/+18
|
* Export CacheMetric as hits+total, rather than hits+misses, as it's easier to ↵Paul "LeoNerd" Evans2015-03-121-5/+6
| | | | derive hit ratio from that
* Remember to emit final linefeed from /metrics page, or Prometheus gets upsetPaul "LeoNerd" Evans2015-03-121-0/+2
|
* Prometheus needs "escaped" label valuesPaul "LeoNerd" Evans2015-03-121-2/+6
|
* Kill unused CounterMetric.fetch() methodPaul "LeoNerd" Evans2015-03-121-3/+0
|
* Use _ instead of . as a metric namespacing separator, for PrometheusPaul "LeoNerd" Evans2015-03-121-3/+11
|
* Have all @metrics.counted use a single metric name vectored on the method ↵Paul "LeoNerd" Evans2015-03-121-2/+9
| | | | name, rather than a brand new scalar counter per counted method
* Bugfix to rendering output of vectored TimerMetricsPaul "LeoNerd" Evans2015-03-121-3/+2

* Rename Metrics' "keys" to "labels"Paul "LeoNerd" Evans2015-03-121-12/+12
|
* Provide some process resource usage metricsPaul "LeoNerd" Evans2015-03-121-0/+27
|
* Neater register_* methods on overall Metrics containerPaul "LeoNerd" Evans2015-03-121-22/+12
|
* Neater implementation of metric render methods by pulling out 'render' as a ↵Paul "LeoNerd" Evans2015-03-121-18/+15
| | | | base method that calls self.render_item
* Initial hack at a TimerMetric; for storing counts + duration accumulatorsPaul "LeoNerd" Evans2015-03-121-0/+48
|
* Ensure that /_synapse/metrics response is UTF-8 encodedPaul "LeoNerd" Evans2015-03-121-1/+2
|
* Implement vector CallbackMetricsPaul "LeoNerd" Evans2015-03-121-2/+6
|
* Neater introspection methods on BaseMetric so that subclasses don't need to ↵Paul "LeoNerd" Evans2015-03-121-4/+11
| | | | touch self.keys directly
* Rename CacheCounterMetric to just CacheMetric; add a CallbackMetric ↵Paul "LeoNerd" Evans2015-03-122-7/+12
| | | | component to give the size of the cache
* Ensure that exceptions while rendering individual metrics don't stop others ↵Paul "LeoNerd" Evans2015-03-121-1/+10
| | | | from being rendered anyway - especially useful for CallbackMetric
* Initial attempt at a scalar callback-based metric to give instantaneous ↵Paul "LeoNerd" Evans2015-03-122-1/+24
| | | | snapshot gauges
* Create the concept of a cachecounter metric; generating two counters ↵Paul "LeoNerd" Evans2015-03-122-7/+47
| | | | specific to caches
* Have the MetricsResource actually render metric countersPaul "LeoNerd" Evans2015-03-121-1/+3
|
* An initial implementation of a 'metrics' instance, similar to a 'logger' for ↵Paul "LeoNerd" Evans2015-03-121-0/+69
| | | | keeping counter stats on method calls
* Initial tiny attempt at (vectorable) counter metricsPaul "LeoNerd" Evans2015-03-121-0/+54
