APACHE SKYWALKING OPEN SOURCE OBSERVABILITY

Observability for
cloud-native and AI.

Understand the systems you run and the AI that works alongside them.
Connect service performance, model usage, and agent activity in one platform.

AI OBSERVABILITY

From model performance
to agent work.

Monitor model and MCP traffic through Envoy AI Gateway. For Claude Code, explore usage patterns, replay conversations, and inspect the work recorded inside them.

Usage Preview

See where your tokens are going.

AI Agent Overview with daily and hourly token heatmaps and reporting agent services.
Horizon · AI Agent Overview

Compare daily and hourly token usage across your agents. Find a busy period, then narrow the investigation to a runtime or conversation.

Conversations Preview

Find the conversation behind the activity.

Conversations list with runtime and title filters, model calls, tool activity, and recorded change counts.
Horizon · Conversations

Filter collected conversations by runtime, time range, or title. Review activity counts and open a task to follow its transcript and execution timeline.

Tools & subagents Preview

Follow the work inside a conversation.

AI Sessionizer replay with a tool execution timeline, main and child stream navigation, and an evidence inspector.
AI Sessionizer · Local replay

Follow model calls and tools on the execution timeline. Switch between the main agent and child streams, then inspect a tool's request, result, and source evidence.

File changes Preview

Read a change with its supporting evidence.

A recorded Write tool change showing a unified file diff, capture source, and supporting evidence.
Horizon · File change inspector

Read a recorded file diff alongside its associated tool call. Inspect its capture source and supporting evidence to understand the change in context.

AI FOR OBSERVABILITY

Bring AI to every investigation.

Explore your cloud-native and AI telemetry through Horizon's assistant or the AI client you already use.

IN HORIZON

Ask. Explore. Understand.

Ask about system health and performance. Get answers with charts, topology, traces, and logs, using the model you configure.
