From 29068fc70a3e5a17a630c2c7fff951572bb5fa21 Mon Sep 17 00:00:00 2001 From: Ivan Topolnjak Date: Thu, 3 Jul 2014 14:36:42 -0300 Subject: ! all: refactor the core metric recording instruments and accomodate UserMetrics This PR is including several changes to the kamon-core, most notably: - Formalize the interface for Histograms, Counters and MinMaxCounters. Making sure that the interfaces are as clean as possible. - Move away from the all Vector[Measurement] based Histogram snapshot to a new approach in which we use a single long to store both the index in the counts array and the frequency on that bucket. The leftmost 2 bytes of each long are used for storing the counts array index and the remaining 6 bytes are used for the actual count, and everything is put into a simple long array. This way only the buckets that actually have values will be included in the snapshot with the smallest possible memory footprint. - Introduce Gauges. - Reorganize the instrumentation for Akka and Scala and rewrite most of the tests of this components to avoid going through the subscription protocol to test. - Introduce trace tests and fixes on various tests. - Necessary changes on new relic, datadog and statsd modules to compile with the new codebase. Pending: - Finish the upgrade of the new relic to the current model. - Introduce proper limit checks for histograms to ensure that we never pass the 2/6 bytes limits. - More testing, more testing, more testing. - Create the KamonStandalone module. --- .../src/main/scala/kamon/standalone/KamonStandalone.scala | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 kamon-core/src/main/scala/kamon/standalone/KamonStandalone.scala (limited to 'kamon-core/src/main/scala/kamon/standalone/KamonStandalone.scala') diff --git a/kamon-core/src/main/scala/kamon/standalone/KamonStandalone.scala b/kamon-core/src/main/scala/kamon/standalone/KamonStandalone.scala new file mode 100644 index 00000000..258cc1b2 --- /dev/null +++ b/kamon-core/src/main/scala/kamon/standalone/KamonStandalone.scala @@ -0,0 +1,11 @@ +package kamon.standalone + +import akka.actor.ActorSystem + +object KamonStandalone { + private lazy val system = ActorSystem("kamon-standalone") + + def registerHistogram(name: String) = { + + } +} -- cgit v1.2.3
