# OpenTelemetry Instrumentation

gitstreams includes optional OpenTelemetry instrumentation to help monitor and understand the sync operation performance.

## Features

The instrumentation provides visibility into:
- Overall sync operation duration
- Time to fetch followed users
- Per-user API call timings (starred repos, owned repos, events)
- Pagination details (pages fetched, items per page)

## Setup

### Prerequisites

You'll need an OpenTelemetry collector running. Here's a quick setup using Docker:

1. Create a `docker-compose.yml` file:

```yaml
version: '3'
services:
otel-collector:
image: otel/opentelemetry-collector:latest
command: ["--config=/etc/otel-collector-config.yaml"]
volumes:
- ./otel-collector-config.yaml:/etc/otel-collector-config.yaml
ports:
- "4318:4318" # OTLP HTTP receiver
- "13133:13133" # Health check
- "55679:55679" # zpages

jaeger:
image: jaegertracing/all-in-one:latest
ports:
- "16686:16686" # Jaeger UI
- "14250:14250" # gRPC receiver
```

2. Create `otel-collector-config.yaml`:

```yaml
receivers:
otlp:
protocols:
http:
endpoint: 0.0.0.0:4318

exporters:
debug:
verbosity: detailed
jaeger:
endpoint: jaeger:14250
tls:
insecure: true

service:
pipelines:
traces:
receivers: [otlp]
exporters: [debug, jaeger]
```

3. Start the collector:

```bash
docker-compose up -d
```

### Running gitstreams with OpenTelemetry

Set the OTEL environment variable to enable tracing:

```bash
export GITHUB_TOKEN=your_token_here
export OTEL_EXPORTER_OTLP_ENDPOINT=localhost:4318
export OTEL_SERVICE_NAME=gitstreams # Optional, defaults to "gitstreams"

./gitstreams
```

### Viewing Traces

Open Jaeger UI in your browser:

```
http://localhost:16686
```

Select the "gitstreams" service and explore the traces to see:
- Total sync operation time
- Per-user processing time
- API call breakdowns
- Pagination details

## Environment Variables

- `OTEL_EXPORTER_OTLP_ENDPOINT`: OTLP endpoint (required to enable tracing)
- Format: `hostname:port` (e.g., `localhost:4318`)
- `OTEL_SERVICE_NAME`: Service name for traces (optional, defaults to "gitstreams")

## Spans

### Top-level spans

- `fetchActivity`: Overall sync operation
- Attributes: `user_count` (number of users followed)

### Per-user spans

- `fetchUserActivity`: Processing a single user
- Attributes: `user` (username)
- `getStarredRepos`: Fetching starred repositories
- Attributes: `user` (username)
- `getOwnedRepos`: Fetching owned repositories
- Attributes: `user` (username)
- `getRecentEvents`: Fetching recent events
- Attributes: `user` (username)

### Pagination spans

- `github.getPaginated`: Overall pagination operation
- Attributes: `path` (API path), `total_pages`, `total_results`
- `github.fetchPage`: Individual page fetch
- Attributes: `path` (full path with params), `page` (page number), `results` (items in page)

## Example: Analyzing Performance

After running with OTEL enabled, you can:

1. Identify slow users: Look at `fetchUserActivity` spans to see which users take longest
2. Understand pagination overhead: Check `github.fetchPage` spans to see how many pages are fetched
3. API rate limiting: Monitor timing patterns to detect rate limit delays
4. Overall performance: Track `fetchActivity` duration over time

## Disabling Instrumentation

Simply omit the `OTEL_EXPORTER_OTLP_ENDPOINT` environment variable. The instrumentation code will use a no-op tracer with zero overhead.

- **Relative timestamps** — "2 hours ago", "yesterday", "last week"
- **Fun taglines** — dynamic header message based on activity volume

## OpenTelemetry Instrumentation (Optional)

gitstreams includes optional OpenTelemetry instrumentation to monitor sync operation performance. Enable it by setting:

```bash
export OTEL_EXPORTER_OTLP_ENDPOINT=localhost:4318
```

See [OTEL_SETUP.md](OTEL_SETUP.md) for detailed setup instructions, including Docker Compose configuration for a local collector and Jaeger UI.

Benefits:
- Monitor sync operation duration
- Track per-user API call timings
- Analyze pagination patterns
- Identify performance bottlenecks
