Khronus Integration

Reporting Metrics to Khronus

Khronus is an open source, distributed and reactive time series database designed to store, retrieve, analyze and process a large amount of custom metrics.

Getting Started

Kamon khronus module is currently available for Scala 2.10, 2.11 and 2.12.

Supported releases and dependencies are shown below.

kamon-khronus	status	jdk	scala	akka
0.6.7	stable	1.7+, 1.8+	2.10, 2.11, 2.12	2.3.x, 2.4.x

To get started with SBT, simply add the following to your build.sbt file:

libraryDependencies += "io.kamon" %% "kamon-khronus" % "0.6.7"

Configuration

Set kamon.khronus.host to point to your Khronus instance using a host:port value like 11.22.33.44:1173. Most likely, you will also want to set kamon.khronus.app-name to the application name you wish to report metric as.

These are the configuration keys available and their default values (taken from the reference.conf file supplied with this module):

kamon {
  khronus {
    host = "127.0.0.1:1173"
    app-name = "kamon-khronus"
    # Time interval in milliseconds to flush the buffer and send the accumulated metrics.
    # It must be less than the smallest time window configured in Khronus.
    interval = 3000
    # Maximum number of measures to hold in memory within intervals.
    # Past this threshold, metrics will be discarded.
    max-measures = 500000
  }
}

Reported Metrics

This reporter will automatically subscribe itself to the following categories:

• counter.
• histogram.
• gauge.
• trace.
• executor-service.

The other important categories like akka-*, system-metrics, and http-server were not included in this initial version due to time constraints. Also, there are no facilities for filtering categories. Please feel free to jump in!
