Last9 is an observability platform that provides analysis of metrics, traces, and logs. ToolJet integrates with Last9 using OpenTelemetry by exporting telemetry data directly to Last9’s OTLP endpoints. This guide walks through setting up observability using Last9.

To use OpenTelemetry with Last9, the required OTLP endpoint must be enabled at the organization level by the Last9 team. Navigate to Integrations > OpenTelemetry, click *Connect*, and submit a request via *Request OpenTelemetry Endpoint Setup*.


## Setting Up Observability Using Last9

### Step 1: Get the Credentials From Last9
Navigate to Integrations > OpenTelemetry, click *Connect* and Copy the the following values:
- **Endpoint URL**
- **Auth Header**

### Step 2: Set the Environment Variables in ToolJet
Set the following environment variables in your ToolJet instance to enable OpenTelemetry.

Replace `<YOUR-LAST9-ENDPOINT>` and `<YOUR-LAST9-AUTH-HEADER>` with the endpoint URL and authentication header obtained in Step 1.
```js
ENABLE_OTEL=true
OTEL_SERVICE_NAME=tooljet

# Last9 Agent endpoints (container-to-container)
OTEL_EXPORTER_OTLP_TRACES=https://<YOUR-LAST9-ENDPOINT>/v1/traces
OTEL_EXPORTER_OTLP_METRICS=https://<YOUR-LAST9-ENDPOINT>/v1/metrics
OTEL_EXPORTER_OTLP_HEADERS=<YOUR-LAST9-AUTH-HEADER>

# Optional but useful while debugging
OTEL_LOG_LEVEL=debug
```

Your ToolJet instance will now begin streaming traces and metrics to Last9.
