Metricator Client

Metricator client was created to help with Metricator daemon communication. It is able to produce different output based on selected format.

Parameters

Parameter Type Description
-application string Name of application to query.
-apps-list bool Request type: applications list.
-config string Path to configuration file. MANDATORY
-metric string Request type: single metric. Name of metric to request.
-metricator-host URL URL to Metricator daemon. (e.g. http://127.0.0.1:34421). MANDATORY
-metricator-timeout integer Timeout in seconds for Metricator Client's HTTP requests. By default - 5 seconds.
-metrics-list bool Request type: list of metrics. Requires -application parameter to be filled.
-output string Type of output to produce (see below).

Request types

One of following parameters should be defined:

  • -apps-list to get listing of applications that is registered at Metricator daemon.
  • -metrics-list with -application parameters to get list of metrics for application which Metricator know.
  • -metric with name of metric and -application (with a name of application) parameters to get specific metric for application which Metricator know.

See Examples section below.

Outputs

Currently Metricator client is able to produce JSON and "Plain By Line" outputs. Their meanings:

  • When -output=json is specified (or -output wasn't specified at all) Metricator Client will just dump response from Metricator Daemon.
  • When -output=plain-by-line is specified Metricator Client will transform received data into line-by-line output, e.g. every application name on separate line, every metric name on separate line, etc.

Examples

  • Get list of applications registered at Metricator daemon line-by-line (for later use with metrics autodiscovery helper):
metricator-client -config=./metricator.yaml -metricator-host http://127.0.0.1:34421 -output plain-by-line -apps-list
  • Get list of metrics for application test in JSON format:
metricator-client -config ./metricator.yaml -metricator-host http://127.0.0.1:34421 -application test -metrics-list
  • Get specific metric for application test:
metricator-client -config ./metricator.yaml -metricator-host http://127.0.0.1:34421 -application test -metric mymegametric
