# Personal AI Infrastructure — Telemetry Module

**Version**: v1.2.3 | **Status**: Active | **Last Updated**: March 2026

## Overview

The Telemetry module provides a complete observability stack for Codomyrmex agents. It integrates **Service Level Objectives (SLOs)**, **Distributed Tracing**, and **Metrics Collection** into a unified interface. This is an **Extended Layer** module that enables PAI agents to self-monitor, debug performance issues, and maintain reliability standards through the LEARN and VERIFY phases.

## PAI Capabilities

### SLO Tracking (Reliability Management)

Define and track Service Level Objectives to ensure agent reliability.

```python
from codomyrmex.telemetry.dashboard.slo import SLOTracker, SLIType

tracker = SLOTracker()

# Define an availability SLO (99.9% success rate)
tracker.create_slo(
    slo_id="api_reliability",
    name="API Availability",
    sli_type=SLIType.AVAILABILITY,
    target=99.9,
    window_days=30
)

# Record events
tracker.record_event("api_reliability", is_good=True)
tracker.record_event("api_reliability", is_good=False)

# Check status
status = tracker.get_status("api_reliability")
print(f"Error Budget Remaining: {status['error_budget_remaining']}%")
```

### Distributed Tracing (Context Propagation)

OpenTelemetry-compatible tracing for tracking requests across module boundaries.

```python
from codomyrmex.telemetry.tracing import get_tracer, trace

tracer = get_tracer("my_service")

@trace("process_data")
def process(data):
    with tracer.span("parse_step") as span:
        span.set_attribute("data.size", len(data))
        # ... logic ...
```

### Metrics Collection (Instrumentation)

Standard metrics types compatible with Prometheus/StatsD.

```python
from codomyrmex.telemetry.metrics import get_metrics

metrics = get_metrics()
requests = metrics.counter("http_requests_total", labels=["method", "status"])
latency = metrics.histogram("request_duration_seconds")

requests.inc(labels={"method": "GET", "status": "200"})
latency.observe(0.15)
```

## Key Exports

| Category | Exports | Purpose |
|----------|---------|---------|
| **SLO** | `SLOTracker`, `SLO`, `SLI`, `SLOViolation` | Reliability tracking & error budgets |

## PAI Algorithm Phase Mapping

| Phase | Telemetry Contribution |
|-------|------------------------|
| **OBSERVE** | `metrics.counter`, `tracer.start_span` — Instrument current execution state |
| **VERIFY** | `SLOTracker.get_status` — Validate performance against targets |
| **LEARN** | `SLOViolation` analysis — Identify patterns of failure for self-improvement |
| **BUILD** | `tracing.trace` — Add visibility to new workflows |

## Architecture Role
