## Prerequisites

## Installation

```bash
curl -O https://raw.githubusercontent.com/last9/last9-k8s-observability/main/last9-otel-setup.sh

## Setting additional log attributes

```yaml
transform/logs/last9:
  error_mode: ignore
  log_statements:
    - context: resource
      statements:
        - set(attributes["service.name"], attributes["k8s.container.name"]) where attributes["service.name"] == ""
        - set(attributes["deployment_environment"], "staging")
```
