Agent Monitoring

Agent Monitoring

Real-time monitoring of AI agent sessions with step-by-step progress tracking.

---

Overview

When the Play Agent runs, Lastest creates an agent session that tracks every step of the 11-step pipeline. You can monitor progress live from the dashboard via the activity feed.

---

Session States

Status	Description
Active	Agent is currently executing steps
Paused	Agent is waiting for human input (plan approval, error resolution)
Completed	Agent finished all steps successfully

---

Activity Feed

The activity feed provides real-time SSE (Server-Sent Events) streaming of agent progress:

• Step-by-step tracking -- see which step the agent is on and what it's doing
• Duration metrics -- how long each step took
• Artifact tracking -- tests created, builds triggered, diffs generated
• Error visibility -- see failures as they happen with full context

Event Types

Event	Description
Agent step started	A new pipeline step begins
Agent step completed	A step finishes (with duration)
Test created	Agent generated a new test
Build triggered	Agent started a test build
Diff approved/rejected	Agent or user acted on a visual diff
Plan submitted	Agent proposed a test plan for review

---

Session History

Past agent sessions are stored and viewable:

• See which sessions ran, when, and their final status
• Review the steps and outcomes of each session
• Track how many tests were generated and fixed

---

How It Works

1. Play Agent starts -- a new agentSession record is created with all 11 steps initialized
2. Steps execute -- each step updates the session's currentStepId and steps array
3. Events stream -- activity events are emitted via SSE for the UI to consume
4. Session completes -- final status and metadata are recorded
