name: Apache SkyWalking
description: >-
  Apache SkyWalking is an open-source APM (Application Performance Monitoring) system that
  provides monitoring, tracing, and diagnosing capabilities for distributed systems in cloud
  native architectures. It supports auto-instrumentation for Java, .NET, Python, Go, Node.js,
  PHP, and Ruby, offering distributed tracing, metrics collection, log aggregation, and
  continuous profiling through a unified observability platform governed by the Apache Software
  Foundation.

- aid: apache-skywalking:apache-skywalking-graphql-query-api
  name: Apache SkyWalking GraphQL Query API
  description: >-
    The SkyWalking GraphQL Query API provides a comprehensive query interface for retrieving
    observability data including traces, metrics, logs, alarms, topology maps, and profiling
    results. It supports metadata queries (services, instances, endpoints), topology queries,
    metrics via SkyWalking Metrics Query Expression (MQE), log queries, trace queries,
    alarm queries, and profiling queries. The API is served on port 12800 and consumed by
    the native UI and CLI tools.

  name: Apache SkyWalking REST API
  description: >-
    The SkyWalking HTTP REST API exposes endpoints on port 12800 for health checks,
    PromQL-compatible metrics queries (Prometheus Query Language), LogQL log queries,
    and dynamic configuration management. PromQL support enables integration with
    Grafana and other Prometheus-compatible visualization tools. LogQL support enables
    integration with Grafana Loki-compatible tooling.

  name: Apache SkyWalking gRPC Data Collect Protocol
  description: >-
    The SkyWalking data collection protocol defines gRPC service definitions for telemetry
    data ingestion from language agents and service mesh proxies. It covers trace data
    (v3), JVM metrics, meter protocol, event reporting, browser performance data,
    instance properties, continuous profiling, eBPF profiling, and log data protocols.
    Agents report data to OAP server on port 11800.
