Zipkin and Apache Druid Integration

Input and output integration overview

The Zipkin Input Plugin allows for the collection of tracing information and timing data from microservices. This capability is essential for diagnosing latency troubles within complex service-oriented environments.

This plugin allows Telegraf to send JSON-formatted metrics to Apache Druid over HTTP, enabling real-time ingestion for analytical queries on high-volume time-series data.

Integration details

Zipkin

This plugin implements the Zipkin HTTP server to gather trace and timing data necessary for troubleshooting latency issues in microservice architectures. Zipkin is a distributed tracing system that helps gather timing data across various microservices, allowing teams to visualize the flow of requests and identify bottlenecks in performance. The plugin offers support for input traces in JSON or thrift formats based on the specified Content-Type. Additionally, it utilizes span metadata to track the timing of requests, enhancing the observability of applications that adhere to the OpenTracing standard. As an experimental feature, its configuration and schema may evolve over time to better align with user requirements and advancements in distributed tracing methodologies.

Apache Druid

This configuration uses Telegraf’s HTTP output plugin with json data format to send metrics directly to Apache Druid, a real-time analytics database designed for fast, ad hoc queries on high-ingest time-series data. Druid supports ingestion via HTTP POST to various components like the Tranquility service or native ingestion endpoints. The JSON format is ideal for structuring Telegraf metrics into event-style records for Druid’s columnar and time-partitioned storage engine. Druid excels at powering interactive dashboards and exploratory queries across massive datasets, making it an excellent choice for real-time observability and monitoring analytics when integrated with Telegraf.

Configuration

Zipkin

[[inputs.zipkin]]
  ## URL path for span data
  # path = "/api/v1/spans"

  ## Port on which Telegraf listens
  # port = 9411

  ## Maximum duration before timing out read of the request
  # read_timeout = "10s"
  ## Maximum duration before timing out write of the response
  # write_timeout = "10s"

Apache Druid

[[outputs.http]]
  ## Druid ingestion endpoint (e.g., Tranquility, HTTP Ingest, or Kafka REST Proxy)
  url = "http://druid-ingest.example.com/v1/post"

  ## Use POST method to send events
  method = "POST"

  ## Data format for Druid ingestion (expects JSON format)
  data_format = "json"

  ## Optional headers (may vary depending on Druid setup)
  # [outputs.http.headers]
  #   Content-Type = "application/json"
  #   Authorization = "Bearer YOUR_API_TOKEN"

  ## Optional timeout and TLS settings
  timeout = "10s"
  # tls_ca = "/path/to/ca.pem"
  # tls_cert = "/path/to/cert.pem"
  # tls_key = "/path/to/key.pem"
  # insecure_skip_verify = false

Input and output integration examples

Zipkin

1. Latency Monitoring in Microservices: Use the Zipkin Input Plugin to capture and analyze tracing data from a microservices architecture. By visualizing the request flow and pinpointing latency sources, development teams can optimize service interactions, improve response times, and ensure a smoother user experience across services.

2. Performance Optimization in Essential Services: Integrate the plugin within critical services to monitor not only the response times but also track specific annotations that could highlight performance issues. The ability to gather span data can help prioritize areas needing performance enhancements, leading to targeted improvements.

3. Dynamic Service Dependency Mapping: With the collected trace data, automatically map service dependencies and visualize them in dashboards. This helps teams understand how different services interact and the impact of failures or slowdowns, ultimately leading to better architectural decisions and faster resolutions of issues.

4. Anomaly Detection in Service Latency: Combine Zipkin data with machine learning models to detect unusual patterns in service latencies and request processing times. By automatically identifying anomalies, operations teams can respond proactively to emerging issues before they escalate into critical failures.

Apache Druid

1. Real-Time Application Monitoring Dashboard: Use Telegraf to collect metrics from application servers and send them to Druid for immediate analysis and visualization in dashboards. Druid’s low-latency querying allows users to interactively explore system behavior in near real-time.

2. Security Event Aggregation: Aggregate and forward security-related metrics such as failed logins, port scans, or process anomalies to Druid. Analysts can build dashboards to monitor threat patterns and investigate incidents with millisecond-level granularity.

3. IoT Device Analytics: Collect telemetry from edge devices via Telegraf and send it to Druid for fast, scalable processing. Druid’s time-partitioned storage and roll-up capabilities are ideal for handling billions of small JSON events from sensors or gateways.

4. Web Traffic Behavior Exploration: Use Telegraf to capture web server metrics (e.g., requests per second, latency, error rates) and forward them to Druid. This enables teams to drill down into user behavior by region, device, or request type with subsecond query performance.
