Monitoring AI coding agent costs and activity on your own machine

说明与用途

使用多 AI 代理的开发者获得了统一的仪表盘，用于监控成本、令牌使用和会话活动，从而加速故障排查和成本优化。

问题

Developers using multiple AI coding agents lacked a unified view of costs, token usage, and session activity, making it hard to diagnose slow or failed sessions.

结果

Developers gain real‑time visibility into AI agent costs and activity, enabling faster diagnosis of failures and optimization of spending.

工作流

• Install AgentMon Start on Windows/macOS/Linux
• Sign in via Codenotary
• Collector parses agent logs into snapshots
• Local server stores snapshots in SQLite
• Dashboard visualizes costs, token usage, tool calls, errors, and security findings
• Use session view to inspect threads, tool calls, and failures
• Use trace waterfall to debug stalled or unexpected sessions
• Set alerts for cost, error, and activity thresholds
• Review recommendations for cost and reliability improvements

证据

I run Claude Code, Cursor, Codex and a handful of sub-agents on my own machines every day.

AgentMon Start reads the session logs your coding agents already write.

来源

The Overview shows spending alongside session counts, token usage and cache hit rate.

来源

The Tools view also aggregates failures across sessions, so you can see whether one tool accounts for most of the errors.

Alerts check every 60 seconds. Depending on your plan, they can flag cost thresholds, spending spikes, error spikes, long-running sessions and unmanaged agent activity.
