Features

• Telemetry Collection and Aggregation - Functions as a distributed system for the transport, streaming, and unification of telemetry data across clusters.
• Telemetry Collectors - Provides a distributed system for centralizing and aggregating telemetry data across complex architectures using a clustered approach.
• Observability Data Routers - Implements mechanisms for directing metrics, logs, and traces to specific destinations based on conditional rules.
• Target Distribution - Automatically divides the load of scraping targets among cluster peers to maintain resiliency.
• Gossip Protocols - Utilizes gossip protocols to synchronize state and connectivity between peer nodes in a distributed cluster.
• Declarative Configuration Engines - Implements a logic-based engine that processes declarative definitions to maintain the desired state of telemetry pipelines.
• Dynamic Configuration Management - Manages and distributes telemetry pipeline settings across a fleet of agents using remote servers and modules.
• Native Kubernetes Resource Integration - Interacts directly with native and custom Kubernetes resources to collect telemetry without requiring a separate operator.
• Telemetry Workload Distribution - Clusters multiple instances together to automatically balance and distribute telemetry collection workloads.
• Expression-Based Configurations - Uses an expression-based configuration syntax to programmatically direct telemetry data through pipelines.
• Consistent Hashing - Utilizes consistent hashing to distribute data collection tasks across nodes, minimizing reorganization during scaling.
• Declarative Pipeline Definitions - Uses a declarative syntax of blocks and expressions to organize telemetry collection and routing settings.
• Declarative Dataflow Graphs - Models telemetry pipelines as a directed graph of interchangeable components that exchange data and configuration.
• Consistent Hashing - Implements consistent hashing to distribute scraping targets and workloads across a cluster of collector nodes.
• Collector Distributions - Functions as an OpenTelemetry collector distribution for collecting, transforming, and routing telemetry data.
• Kubernetes Monitors - Gathers telemetry data directly from Kubernetes resources to monitor cluster health and performance.
• Observability Pipelines - Ships a comprehensive system for collecting, formatting, and routing metrics, logs, traces, and profiles to monitoring backends.
• Pipeline Flow Visualizers - Provides a web-based interface to visualize internal state and data flow across telemetry components.
• Pipeline Visualization - Features a built-in user interface for visualizing and validating the flow of telemetry data from sources to destinations.
• Remote Configuration Retrieval - Retrieves pipeline definitions from a central server to manage settings across a fleet based on node identity.
• Reusable Configuration Blocks - Groups common pipeline patterns into reusable modules that can be shared across projects and teams.
• Native Telemetry Agents - Acts as a native agent that gathers cluster metrics and logs by interacting directly with Kubernetes resources.
• Debug Data Streams - Displays a live feed of telemetry data with sampling and searching capabilities for real-time troubleshooting.
• Expression Languages - Uses a custom expression language to calculate dynamic settings and attribute values at runtime.
• Configuration Module Imports - Loads reusable pipeline definitions from local files, repositories, or endpoints.
• Namespace Imports - Loads reusable pipeline patterns into isolated namespaces to prevent configuration conflicts.
• Dynamic Configuration Evaluators - Calculates attribute values using arithmetic operations and environment variables to adapt settings without manual updates.
• Configuration Block Linking - References exports from one configuration block in another to create interdependent data flows and shared settings.
• Parameterized Configuration Components - Allows the definition of custom components that accept arguments and export values to reuse logic across configurations.
• Runtime State Inspection - Offers a web-based interface for analyzing the internal runtime state and execution flow of telemetry pipelines.
• Real-Time Pipeline Inspectors - Provides real-time visualization of data flows and component states to troubleshoot observability configuration issues.
