# Session Tracking Quick Start Guide

**Last Updated**: 2026-02-06
**Status**: ✅ Production Ready
**Implementation**: Automatic via AdminShell inheritance

## Overview

Session tracking automatically monitors admin shell lifecycle events (start/end) across your entire ecosystem. No configuration required - any shell extending `AdminShell` gets session tracking automatically.

## How Session Tracking Works

```
┌─────────────────────────────────────────────────────────────┐
│  1. User starts shell: $ python -m mahavishnu shell        │
│  2. AdminShell.start() initializes SessionEventEmitter       │
│  3. Session start event emitted → Session-Buddy MCP          │
│  4. Session record created with rich metadata               │
├─────────────────────────────────────────────────────────────┤
│  5. User works in shell (commands executed)                │
│  6. Session remains active and tracked                      │
├─────────────────────────────────────────────────────────────┤
│  7. User types exit()                                       │
│  8. Session end event emitted → Session-Buddy MCP           │
│  9. Session record updated with duration                    │
└─────────────────────────────────────────────────────────────┘
```

## Quick Start (5 Minutes)

### Step 1: Verify Session-Buddy Running

Session tracking requires Session-Buddy MCP server:

```bash
# Check if Session-Buddy MCP is running
curl http://localhost:8678/health

# If not running, start it:
cd /Users/les/Projects/session-buddy
session-buddy mcp start
```

### Step 2: Set Authentication (Optional)

For development, you can skip authentication. For production:

```bash
# Generate secure secret
export MAHAVISHNU_CROSS_PROJECT_AUTH_SECRET="$(python -c 'import secrets; print(secrets.token_urlsafe(32))')"
```

### Step 3: Start Shell and Verify Tracking

```bash
# Start Mahavishnu shell
python -m mahavishnu shell

# You should see in banner:
# Session Tracking: ✓ Enabled (Session-Buddy connected)
#   Session ID: sess_abc123
```

### Step 4: Check Active Sessions

```bash
# In another terminal, query active sessions
session-buddy list-sessions --type admin_shell

# Output:
┌──────────────┬──────────────┬──────────┬────────────────┐
│ Session ID   │ Component    │ User     │ Started        │
├──────────────┼──────────────┼──────────┼────────────────┤
│ sess_abc123  │ mahavishnu   │ les      │ 10:30:00       │
└──────────────┴──────────────┴──────────┴────────────────┘
```

### Step 5: Exit Shell and Verify Session End

```python
# In the shell
Mahavishnu> exit()  # Clean exit with session_end event

# In terminal, verify session ended
session-buddy show-session sess_abc123

# Output:
┌────────────────────────────────────────────────────────────┐
│ Session: sess_abc123                                        │
├────────────────────────────────────────────────────────────┤
│ Status:       ended                                         │
│ Start Time:   2026-02-06 10:30:00 UTC                      │
│ End Time:     2026-02-06 10:35:00 UTC                      │
│ Duration:     300 seconds (5 minutes)                      │
└────────────────────────────────────────────────────────────┘
```

## What Gets Tracked

Each session captures:

```json
{
    "session_id": "sess_abc123",
    "component_name": "mahavishnu",
    "shell_type": "MahavishnuShell",
    "pid": 12345,
    "username": "les",
    "hostname": "mbp-local",
    "start_time": "2026-02-06T10:30:00Z",
    "end_time": "2026-02-06T10:35:00Z",
    "duration_seconds": 300,
    "python_version": "3.13.0",
    "platform": "macOS-15.2-arm64-arm-64bit",
    "working_directory": "/Users/les/Projects/mahavishnu",
    "metadata": {
        "component_version": "1.0.0",
        "cli_enabled": true,
        "adapters": ["llamaindex", "agno", "prefect"]
    }
}
```

## Common Use Cases

### 1. Monitor Active Shells

```bash
# See all active admin shells across ecosystem
session-buddy list-sessions --type admin_shell

# Filter by component
session-buddy list-sessions --component mahavishnu

# Filter by user
session-buddy list-sessions --user les
```

### 2. Audit Admin Access

```bash
# Review all admin shell sessions for past week
session-buddy list-sessions \
    --type admin_shell \
    --after "2026-02-01" \
    --before "2026-02-08"

# Export to CSV
session-buddy list-sessions --type admin_shell --output sessions.csv
```

### 3. Find Long-Running Shells

```bash
# Find shells running > 1 hour
session-buddy list-sessions --duration-greater 3600

# Find potentially stuck shells
session-buddy list-sessions --duration-greater 86400  # > 24 hours
```

### 4. Debug Shell Issues

```bash
# Get detailed session info
session-buddy show-session sess_abc123

# Check session duration
session-buddy show-session sess_abc123 --format json | jq '.duration_seconds'
```

## Troubleshooting

### Problem: Session Tracking Shows "✗ Disabled"

**Diagnosis**:
```bash
# Check if Session-Buddy is running
curl http://localhost:8678/health

# Expected: {"status": "healthy"}
```

**Solution**:
```bash
# Start Session-Buddy MCP
cd /Users/les/Projects/session-buddy
session-buddy mcp start
```

### Problem: Session ID is None

**Symptoms**: Shell starts but `shell.session_id` is `None`

**Causes**:
- Session-Buddy MCP unavailable
- Network connectivity issue
- Authentication failure

**Solution**:
```bash
# Check logs for specific error
# In shell:
Mahavishnu> import logging
Mahavishnu> logging.basicConfig(level=logging.DEBUG)
Mahavishnu> # Look for "Session-Buddy MCP unavailable"

# Verify Session-Buddy reachable
curl http://localhost:8678/health

# Continue using shell (works without tracking)
```

### Problem: Session End Not Recorded

**Symptoms**: Session start recorded but end time missing

**Causes**:
- Shell crashed (not clean exit)
- Session-Buddy unavailable at exit
- Network timeout

**Solution**:
```bash
# Use exit() for clean shutdown
Mahavishnu> exit()  # Triggers session_end event
# Avoid: Ctrl+C (may skip cleanup)

# Manually end stuck sessions
session-buddy end-session sess_abc123
```

### Problem: Circuit Breaker Open

**Symptoms**: "Circuit breaker opened" in logs

**Meaning**: Session-Buddy failed 3 consecutive times

**Behavior**:
- Session tracking disabled for 60 seconds
- Automatic retry after timeout
- Shell continues normally

**Solution**:
```bash
# Wait 60 seconds for circuit to reset
# OR fix Session-Buddy connectivity:

# Restart Session-Buddy
cd /Users/les/Projects/session-buddy
session-buddy mcp restart

# Check network
telnet localhost 8678

# Verify authentication
echo $MAHAVISHNU_CROSS_PROJECT_AUTH_SECRET
```

## Testing Session Tracking

### Manual Test

```bash
# Terminal 1: Start Session-Buddy
cd /Users/les/Projects/session-buddy
session-buddy mcp start

# Terminal 2: Start shell with debug logging
cd /Users/les/Projects/mahavishnu
python -c "
import logging
logging.basicConfig(level=logging.DEBUG)

from mahavishnu.core.app import MahavishnuApp
from mahavishnu.shell import MahavishnuShell

app = MahavishnuApp()
shell = MahavishnuShell(app)
print(f'Session ID: {shell.session_id}')
"

# Terminal 3: Verify session created
session-buddy list-sessions --type admin_shell

# Terminal 2: Exit shell (in Python)
# Type: exit() or Ctrl+D

# Terminal 3: Verify session ended
session-buddy show-session <session_id>
```

### Automated Test

```python
# tests/integration/test_session_tracking_e2e.py
import pytest
from unittest.mock import AsyncMock, patch

@pytest.mark.asyncio
async def test_session_lifecycle():
    """Test session start and end events."""
    with patch("oneiric.shell.session_tracker.SessionEventEmitter") as mock_emitter:
        # Configure mock
        mock_emitter.return_value.emit_session_start = AsyncMock(
            return_value="sess_test123"
        )
        mock_emitter.return_value.emit_session_end = AsyncMock(return_value=True)

        # Create shell
        from mahavishnu.shell import MahavishnuShell
        from mahavishnu.core.app import MahavishnuApp

        app = MahavishnuApp()
        shell = MahavishnuShell(app)
        shell.session_tracker = mock_emitter.return_value

        # Test session start
        await shell._notify_session_start()
        assert shell.session_id == "sess_test123"
        shell.session_tracker.emit_session_start.assert_called_once()

        # Test session end
        await shell._notify_session_end()
        shell.session_tracker.emit_session_end.assert_called_once()
```

Run tests:
```bash
pytest tests/integration/test_session_tracking_e2e.py -v
```

## Best Practices

### 1. Use Clean Exit

Always use `exit()` for clean shutdown:

```python
# GOOD - Triggers session_end event
Mahavishnu> exit()

# AVOID - May skip cleanup
# Ctrl+C
```

### 2. Monitor Session Duration

Track long-running shells that may indicate issues:

```bash
# Find shells > 1 hour
session-buddy list-sessions --duration-greater 3600

# Set up alerting for > 24 hours
session-buddy list-sessions --duration-greater 86400 | \
    mail -s "Long-running shells detected" admin@example.com
```

### 3. Audit Admin Access Regularly

```bash
# Weekly audit report
session-buddy list-sessions \
    --type admin_shell \
    --after "$(date -v-7d +%Y-%m-%d)" \
    --output admin_audit_$(date +%Y%m%d).csv

# Review for unusual activity
# - Unknown users
# - Unusual times (3 AM sessions)
# - Long durations
```

### 4. Use Authentication in Production

```bash
# Generate strong secret for production
export MAHAVISHNU_CROSS_PROJECT_AUTH_SECRET="$(python -c 'import secrets; print(secrets.token_urlsafe(32))')"

# Add to deployment configuration
# Kubernetes: kubectl create secret generic mahavishnu-auth --from-literal=secret=$MAHAVISHNU_CROSS_PROJECT_AUTH_SECRET
# Docker: docker run -e MAHAVISHNU_CROSS_PROJECT_AUTH_SECRET=...
# Terraform: See examples in docs/
```

### 5. Clean Up Stuck Sessions

```bash
# Find sessions without end time
session-buddy list-sessions --type admin_shell --incomplete

# Manually end stuck sessions
session-buddy end-session sess_abc123

# Bulk cleanup (careful!)
session-buddy list-sessions --incomplete --format json | \
    jq -r '.[].session_id' | \
    xargs -I {} session-buddy end-session {}
```

## Configuration Reference

### Environment Variables

```bash
# Cross-project authentication (optional for development)
export MAHAVISHNU_CROSS_PROJECT_AUTH_SECRET="<32-byte-url-safe-secret>"

# Session-Buddy MCP endpoint (default: http://localhost:8678/mcp)
export SESSION_BUDDY_MCP_ENDPOINT="http://localhost:8678/mcp"

# Session-Buddy path (for stdio transport)
export SESSION_BUDDY_PATH="/Users/les/Projects/session-buddy"
```

### Shell Configuration

Session tracking is automatic, but you can verify it in shell:

```python
# Check session tracking status
Mahavishnu> print(shell.session_id)
'sess_abc123'

# Check tracking availability
Mahavishnu> print(shell.session_tracker.available)
True

# Check circuit breaker state
Mahavishnu> print(shell.session_tracker._circuit_open_until)
None  # Circuit closed, tracking active
```

## Advanced Usage

### Query Session History

```bash
# Last 10 sessions
session-buddy list-sessions --limit 10

# Filter by date range
session-buddy list-sessions --after "2026-02-01" --before "2026-02-07"

# Filter by component
session-buddy list-sessions --component mahavishnu

# Export to JSON
session-buddy list-sessions --format json > sessions.json

# Export to CSV
session-buddy list-sessions --format csv > sessions.csv
```

### Session Analytics

```bash
# Average session duration
session-buddy analytics --type admin_shell --metric duration

# Sessions per day
session-buddy analytics --type admin_shell --metric count --period daily

# Unique users
session-buddy analytics --type admin_shell --metric unique_users

# Peak usage hours
session-buddy analytics --type admin_shell --metric peak_hours
```

### Integration with Monitoring

```python
# Alert on long-running shells
import requests
import time

def check_long_running_sessions():
    """Alert on shells running > 1 hour."""
    response = requests.get("http://localhost:8678/api/sessions")
    sessions = response.json()

    for session in sessions:
        if session.get("duration_seconds", 0) > 3600:
            # Send alert
            send_alert(
                f"Long-running shell detected: {session['session_id']}\n"
                f"Component: {session['component_name']}\n"
                f"Duration: {session['duration_seconds']}s\n"
                f"User: {session['username']}"
            )

if __name__ == "__main__":
    check_long_running_sessions()
```
