OpenTsDb Metrics

vertx-opentsdb is a metrics client library for the Vert.x toolkit, designed to send application and service metrics to an OpenTSDB cluster. It provides efficient, non-blocking communication with OpenTSDB, enabling real-time monitoring and performance tracking for distributed systems.

Key Features

• Dedicated Connections — Maintains one NIO socket connection per configured OpenTSDB endpoint for efficient data transmission.
• Configurable Buffering — Flushes metrics on a timer-based schedule with configurable buffer sizes and backlog limits.
• Tag Support — Allows default and per-metric tags for detailed metric categorization and filtering.
• Batch Operations — Supports adding single metrics or batches of metrics via JSON messages over the event bus.
• SPI Integration — Automatically publishes Vert.x framework metrics (e.g., HTTP calls, event bus messages) when enabled.
• Error Handling — Provides event bus notifications for asynchronous errors like write failures or invalid data submissions.

Philosophy

The library emphasizes non-blocking I/O and efficient resource usage, leveraging Vert.x's reactive model to handle metric publishing without blocking application threads.
