Application Performance Monitoring (APM) Market: AgentATC: Observability for Multi-Agent Coordination
AgentATC is a real three-agent workflow (Planner, Executor, Critic) developed as part of an Agents of SigNoz hackathon to demonstrate observability for multi-agent LLM systems. Unlike traditional APM, AgentATC instruments every inter-agent hand-off as first-class OpenTelemetry spans (e.g., agent.execute, agent.handoff, agent.review), recording initiator, receiver, and reason to make coordination directly observable. SigNoz is used end-to-end for traces, metrics, and logs, with dashboards and alerts (Task Thrashing, Task Stalled) and a Copilot that queries SigNoz MCP Server (signoz_search_traces, signoz_get_trace_details, signoz_search_logs) to diagnose coordination failures. The project exposes failure modes such as thrashing, stalled tasks, and redundant work that standard observability metrics often miss.
Demonstrates a practical observability approach for coordination failures in multi-agent LLM systems using OpenTelemetry and SigNoz—valuable to teams building agentic workflows but not a major platform policy or industry-shifting announcement.
Wichtigste Kernpunkte & Evidenz
- AgentATC implements a real three-agent workflow (Planner, Executor, Critic) to produce a competitive analysis report.
- Every agent hand-off is recorded as an OpenTelemetry span (examples: agent.execute, agent.handoff, agent.review) and includes who initiated, who received, and why the hand-off occurred.
- Traces, metrics, and logs flow through SigNoz; coordination metrics are computed from raw telemetry in SigNoz's query layer and displayed on dashboards (Swarm Health Overview, Thrash Leaderboard).
- A Copilot component uses SigNoz's MCP Server and APIs (signoz_search_traces, signoz_get_trace_details, signoz_search_logs) to investigate agent coordination failures and report causes (e.g., tooling gaps).
- The demo intentionally reproduces a coordination failure where a Datadog subtask cannot retrieve pricing, causing five rejections, five review iterations, and an escalation visible in the trace and Thrash Leaderboard.
