![Trace](trace.png)

This package provides OpenTelemetry-compliant tracing to Python
applications for the collection of distributed tracing and performance metrics in [Cisco Telescope](https://console.telescope.app/?utm_source=github).

## Installation

### Install packages
> To install Cisco OpenTelemetry Distribution simply run:

```sh
pip install cisco-telescope
```

### Install dependencies
> To install all supported instrumentation frameworks run:
```sh
telescope-bootstrap
```


### Library initialization
> Cisco OpenTelemetry Distribution is activated and instruments the supported libraries once the `tracing.init()` has returned.

```python
from cisco_telescope import tracing

tracing.init(
  service_name="<your-service-name>",
  cisco_token="<your-telescope-token>"
)
```

### OpenTelemetry Collector Configuration

> By default, Cisco OpenTelemetry Distribution exports data directly to [Cisco Telescope's](https://console.telescope.app/?utm_source=github) infrastructure backend.
> **Existing** OpenTelemetery Collector is supported, the following configuration can be applied

#### Configure custom trace exporter

> Cisco OpenTelemetry Distribution supports configure multiple custom exporters.
> Example for create OtlpGrpc Span exporter to local OpenTelemetry collector:

```python
from cisco_telescope import tracing, options

tracing.init(
  service_name="<your-service-name>",
  cisco_token="<your-telescope-token>",
  exporters=[
    options.ExporterOptions(
      exporter_type="otlp-grpc",
      collector_endpoint="grpc://localhost:4317"
    ),
  ]
)

```

#### Configure custom OpenTelemetry collector to export trace data to [Cisco Telescope's](https://console.telescope.app/?utm_source=github) external collector.

```yaml
collector.yaml ...

exporters:
  otlphttp:
    traces_endpoint: https://production.cisco-udp.com/trace-collector:80
    headers:
      authorization: <Your Telescope Token>
    compression: gzip


service:
  pipelines:
    traces:
      exporters: [otlphttp]
```

### Existing OpenTelemetry Instrumentation

> Notice: Only relevant if interested in streaming existing OpenTelemetry workloads.
> [Cisco Telescope](https://console.telescope.app/?utm_source=github). supports native OpenTelemetery traces.
```python
from opentelemetry import trace
from opentelemetry.sdk.resources import Resource
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor

from opentelemetry.exporter.otlp.proto.http.trace_exporter import (
    OTLPSpanExporter as OTLPHTTPExporter,
)

provider = TracerProvider(resource=Resource.create())
trace.set_tracer_provider(provider)

http_exporter = OTLPHTTPExporter(
  endpoint="https://production.cisco-udp.com/trace-collector:80",
  headers= {
    "authorization": "<Your Telescope Token>",
  },
)

processor = BatchSpanProcessor(http_exporter)
provider.add_span_processor(processor)
```

## Supported Runtimes
Cisco OpenTelemetry Distribution supports Python 3.6+

## Frameworks

> Cisco OpenTelemetry Python Distribution is extending Native OpenTelemetry, supported frameworks [available here](https://github.com/open-telemetry/opentelemetry-python-contrib/tree/main/instrumentation).

## Supported Libraries

> Cisco OpenTelemetry Python Distribution is extending Native OpenTelemetry, supported libraries [available here](https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/metapackages/auto-instrumentations-node#supported-instrumentations).

Cisco OpenTelemetry Python Distribution provides out-of-the-box instrumentation (tracing) and advanced **payload collections** for many popular frameworks and libraries.
