Axiom is a serverless log analytics platform that helps you store, search, and analyze massive amounts of data. By exporting your Cloudflare Workers application telemetry to Axiom, you can:
11+
- Store and query logs and traces at scale
12+
- Create dashboards and alerts to monitor your Workers
13+
14+
![Trace view with timing information displayed on a timeline](~/assets/images/workers-observability/axiom-example.png)
15+
16+
This guide will walk you through exporting OpenTelemetry-compliant traces and logs to Axiom from your Cloudflare Worker application
17+
18+
## Prerequisites
19+
20+
Before you begin, ensure you have:
21+
22+
- An active [Axiom account](https://app.axiom.co/register) (free tier available)
23+
- A deployed Worker that you want to monitor
24+
- An Axiom dataset to send data to
25+
26+
## Step 1: Create a dataset
27+
28+
If you don't already have a dataset to send data to:
29+
1. Log in to your [Axiom account](https://app.axiom.co/)
30+
2. Navigate to **Datasets** in the left sidebar
31+
3. Click **New Dataset**
32+
4. Enter a name (e.g. `cloudflare-workers-otel`)
33+
5. Click **Create Dataset**
34+
35+
## Step 2: Get your Axiom API token and dataset
36+
37+
1. Navigate to **Settings** in the left sidebar
38+
2. Click on **API Tokens**
39+
3. Click **Create API Token**
40+
4. Configure your API token:
41+
- **Name**: Enter a descriptive name (e.g., `cloudflare-workers-otel`)
42+
- **Permissions**: Select **Ingest** permission (required for sending telemetry data)
43+
- **Datasets**: Choose which datasets this token can write to, or select **All Datasets**
44+
5. Click **Create**
45+
6. **Important**: Copy the API token immediately and store it securely - you won't be able to see it again
46+
47+
The API token will look something like: `xaat-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`
48+
49+
## Step 3: Configure Cloudflare destinations
50+
51+
Now you'll create destinations in the Cloudflare dashboard that point to Axiom.
52+
53+
### Axiom OTLP endpoints
54+
55+
Axiom provides separate OTLP endpoints for traces and logs:
56+
- **Traces**: `https://api.axiom.co/v1/traces`
57+
- **Logs**: `https://api.axiom.co/v1/logs`
58+
59+
### Configure trace or logs destination
60+
61+
1. Navigate to your Cloudflare account's [Workers Observability](https://dash.cloudflare.com/?to=/:account/workers-and-pages/observability/pipelines) section
62+
2. Click **Add destination**
63+
3. Configure your trace destination:
64+
- **Destination Name**: `axiom-traces` (or any descriptive name)
65+
- **Destination Type**: Select **Traces**
66+
- **OTLP Endpoint**: `https://api.axiom.co/v1/traces` (or `/v1/logs`)
67+
- **Custom Headers**: Add two required headers:
68+
- Authentication header
69+
- Header name: `Authorization`
70+
- Header value: `Bearer <your-api-token>`
71+
- Dataset header:
72+
- Header name: `X-Axiom-Dataset`
73+
- Header value: Your dataset name (e.g., `cloudflare-workers-otel`)
74+
4. Click **Save**
75+
76+
## Step 3: Configure your Worker
77+
78+
With your destinations created in the Cloudflare dashboard, update your Worker's configuration to enable telemetry export.
79+
80+
<WranglerConfig>
81+
82+
```json
83+
{
84+
"observability": {
85+
"traces": {
86+
"enabled": true,
87+
// Must match the destination name in the dashboard
88+
"destinations": ["axiom-traces"]
89+
},
90+
"logs": {
91+
"enabled": true,
92+
// Must match the destination name in the dashboard
93+
"destinations": ["axiom-logs"]
94+
}
95+
}
96+
}
97+
```
98+
99+
</WranglerConfig>
100+
101+
After updating your configuration, deploy your Worker for the changes to take effect.
102+
103+
:::note
104+
It may take a few minutes after deployment for data to appear in Axiom.

Grafana Cloud is a fully managed observability platform that provides visualization, alerting, and analytics for your telemetry data. By exporting your Cloudflare Workers telemetry to Grafana Cloud, you can:
10+
- Visualize distributed traces in **Grafana Tempo** to understand request flows and performance bottlenecks
11+
- Query and analyze logs in **Grafana Loki** alongside your traces
12+
13+
This guide will walk you through configuring Cloudflare Workers to export OpenTelemetry-compliant traces and logs to your Grafana Cloud stack.
14+
