To link Grafana's explore page to Thanos alerts using the --alert.query-url flag, set the --alert.query-url to the URL of your Grafana instance. This URL will be used in the UI to link alerts to the Grafana explore page. For example:

thanos rule \
    --alert.query-url "http://your-grafana-instance:3000" \
    ...

This configuration tells Thanos to use the specified URL as the base for linking alerts in the UI, allowing users to navigate directly to the Grafana explore page for further investigation ^[1].

To resolve the 404 error when linking Thanos alerts to Grafana's explore page, ensure that the --alert.query-url is correctly formatted to match Grafana's expected URL structure for the explore page. Typically, the URL should include the path to the explore page, such as:

--alert.query-url="http://your-grafana-instance:3000/explore"

Make sure that the URL points directly to the explore page and that any necessary query parameters or paths specific to your Grafana setup are included. If Grafana requires additional parameters to access the explore page, you may need to append them to the URL. Additionally, verify that the Grafana instance is accessible from the network where Thanos is running.

@dosu Still not work

To address the issue of the 404 error when linking Thanos alerts to Grafana's explore page, ensure that the URL structure is correct and includes all necessary query parameters. Grafana's explore page typically requires specific parameters to function correctly.

Here's a general approach you can try:

1. Verify the Base URL: Ensure that the base URL is correct and accessible from Thanos. It should be something like http://your-grafana-instance:3000.

2. Include the Explore Path: Append /explore to the base URL to direct to the explore page.

3. Add Required Query Parameters: Grafana's explore page might require specific query parameters. For example, you might need to include parameters like orgId, left, right, etc., depending on your Grafana setup.

Here's an example of how the URL might look:

--alert.query-url="http://your-grafana-instance:3000/explore?orgId=1&left=metrics"

Replace orgId and other parameters with values specific to your Grafana setup. If you're unsure about the exact parameters, you can manually navigate to the explore page in Grafana and observe the URL structure in your browser's address bar.

Additionally, ensure that any network or proxy configurations allow access to Grafana from Thanos, as misconfigurations can also lead to 404 errors ^[1].

For anyone landing here, this is how i was able to solve it. I deploy my thanos-ruler via an Helm chart in Kubernetes.

        - '--alert.query-url=https://grafana.example.com'
        - '--alert.query-template=/explore?schemaVersion=1&panes=%7B%22u3j%22%3A%7B%22datasource%22%3A%22{{.Values.datasourceUid}}%22%2C%22queries%22%3A%5B%7B%22refId%22%3A%22A%22%2C%22expr%22%3A%22{{`{{.Expr}}`}}%22%2C%22range%22%3Atrue%2C%22instant%22%3Atrue%2C%22datasource%22%3A%7B%22type%22%3A%22prometheus%22%2C%22uid%22%3A%22{{.Values.datasourceUid}}%22%7D%2C%22editorMode%22%3A%22code%22%2C%22legendFormat%22%3A%22__auto%22%7D%5D%2C%22range%22%3A%7B%22from%22%3A%22now-1h%22%2C%22to%22%3A%22now%22%7D%2C%22compact%22%3Afalse%7D%7D'

Based on Grafana's Generate Explore URLs from External Tools docs

The plan is to provide an URL encoded JSON object in the panes= query parameter of the request.

Using an online tool like meyerweb/dencoder we can see the shape of the JSON object.

Notice how i'm using Helm templates to render the datasource UID ({{ .Values.datasourceUid }}) but use raw string interpolation to render the golang template of the Prometheus expression:

{{`{{.Expr}}`}}

I’m no longer use Thanos and switch to Grafana Mimir, so I can’t confirm or deny if it works or not.
