StatsD

StatsD is an open-source standard and, by extension, a toolkit designed for sending, collecting, and aggregating custom metrics from diverse applications. Initially, StatsD denoted a daemon crafted by Etsy using Node.js.

This tutorial demonstrates installing and running StatsD using OpenTelemetry to send your metrics to Coralogix.

Prerequisites

• Otel-contrib installed

• Coralogix account

Deploy using Otel

STEP 1. Save this config file as config.yaml:

receivers:
  statsd:
    endpoint: "localhost:8125"
    aggregation_interval: 30s
    
processors:
  batch:
    send_batch_size: 1024
    send_batch_max_size: 2048
    timeout: "1s"
  
exporters:
  coralogix:
    domain: "eu2.coralogix.com"
    private_key: "<private_key>"
    application_name: "applicationName"
    subsystem_name: "subsystemName"
    timeout: 30s
  
service:
  pipelines:
    metrics:
      receivers: [ statsd ]
      processors: [ batch ] 
      exporters: [ coralogix ]

STEP 2. Replace the private_key with your Send-Your-Data API key, and the coralogix_domain with your Coralogix domain.

STEP 3. Run the config file.

otelcol-contrib --config config.yaml

Deploy using Docker

STEP 1. To deploy StatsD using Docker, change the endpoint to 0.0.0.0:8125 in the config.yaml file.

receivers:
  statsd:
    endpoint: "0.0.0.0:8125"

STEP 2. Run these commands to deploy the configuration:

docker pull otel/opentelemetry-collector-contrib
docker run -d -v ./config.yaml:/etc/otelcol-contrib/config.yaml -p 8125:8125/udp otel/opentelemetry-collector-contrib

Validation

Test Metrics

To send test metrics, run the following command to test the configuration:

echo "test_metrics:65|c|#tag_1:value,tag_2:value_2" | nc -u -w1 127.0.0.1 8125
echo "test_metrics:65|g|#tag_1:value,tag_2:value_2" | nc -u -w1 127.0.0.1 8125

Access your Grafana account to view the metrics sent.

Timer Metrics

Send timer metrics to Coralogix with sum and count attributes:

receivers:
  statsd:
    endpoint: "0.0.0.0:8125"
    is_monotonic_counter: true
    aggregation_interval: 30s
    enable_metric_type: true
    timer_histogram_mapping:
      - statsd_type: "timer"
        observer_type: "summary"

To send metrics, use this command:

echo "timer_metrics:65|ms|#tag_1:value,tag_2:value_2" | nc -u -w1 127.0.0.1 8125
