Agentic Infrastructure: Replacing Splunk with Claude Code Agents for Server Monitoring

A developer on r/ClaudeAI shared a production setup where every service is a claude-code session — the router, per-host monitors, dashboard tile poller — all wired via a WebSocket hub. They originally planned Splunk or traditional server monitoring but pivoted to this agentic approach.

Architecture Breakdown

• WebSocket hub — all agent sessions route messages to each other through a central hub.
• Watchers — plain bash scripts detect host events. Cost: near-zero at idle. The LLM only wakes for the drain cycle every 5 minutes.
• Dashboard tile registry — each tile is a saved natural-language question (e.g., disk % across all monitors). The router re-fires these on a schedule, caches results in SQLite.
• Alerting with context — when something breaks, the agents self-diagnose and push a Slack alert with context, not just a raw threshold like disk >= 80%.

Why This Matters

Traditional monitoring pipelines require separate tools for collection, storage, alerting, and dashboards — each with its own config and integration. This agentic approach collapses that into a single stack where LLM agents interpret telemetry, run diagnostics, and produce human-readable alerts. The bash watchers keep the idle cost near zero; the LLM cycles keep inference cost predictable.

Who It's For

Developers who run their own infrastructure and want to experiment with replacing or augmenting traditional monitoring tools with AI agents, especially those already comfortable with Claude Code.
