Consume API Endpoints in Prometheus format

Prometheus is a powerful open-source monitoring and alerting toolkit widely used for metrics collection and visualization. You can export Pipe endpoints in Prometheus format to integrate your Tinybird data into your monitoring stack.

Prerequisites

This guide assumes you have a Tinybird Workspace with an active Data Source, Pipes, and at least one API Endpoint.

Structure data for Prometheus

To export the Pipe output in Prometheus format, data must conform to the following structure:

Mandatory columns

  • name (String): The name of the metric.
  • value (Number): The numeric value for the metric.

Optional columns

  • help (String): A description of the metric.
  • timestamp (Number): A Unix timestamp for the metric.
  • type (String): Defines the metric type (counter, gauge, histogram, summary, untyped, or empty).
  • labels (Map(String, String)): A set of key-value pairs providing metric dimensions.

Example

Here’s an example of a Tinybird Pipe query that outputs two metrics, http_request_count and http_request_duration_seconds, in the same query. Both metrics include labels for method and status_code.

SELECT
    -- Metric 1: http_request_count
    'http_request_count' AS name,
    toFloat64(count(*)) AS value,
    'Total number of HTTP requests' AS help,
    'counter' AS type,
    map('method', method, 'status_code', status_code) AS labels
FROM
    http_requests
GROUP BY
    method, status_code

UNION ALL

SELECT
    -- Metric 2: http_request_duration_seconds
    'http_request_duration_seconds' AS name,
    avg(request_time) AS value,
    'Average HTTP request duration in seconds' AS help,
    'gauge' AS type,
    map('method', method, 'status_code', status_code) AS labels
FROM
    http_requests
GROUP BY
    method, status_code

ORDER BY
    name

Export Tinybird Pipe endpoint in Prometheus format

Export Pipe data in Prometheus format by appending .prometheus to your API endpoint URI. For example:

https://api.tinybird.co/v0/pipes/your_pipe_name.prometheus

The following is an example Prometheus output:

# HELP http_request_count Total number of HTTP requests
# TYPE http_request_count counter
http_request_count{method="PUT",status_code="203"} 1
http_request_count{method="PATCH",status_code="203"} 1
http_request_count{method="DELETE",status_code="201"} 4
http_request_count{method="POST",status_code="203"} 1
http_request_count{method="OPTIONS",status_code="203"} 1
http_request_count{method="PATCH",status_code="204"} 1
http_request_count{method="PUT",status_code="204"} 1
http_request_count{method="HEAD",status_code="203"} 1
http_request_count{method="GET",status_code="201"} 4
http_request_count{method="POST",status_code="204"} 1
http_request_count{method="GET",status_code="203"} 1
http_request_count{method="POST",status_code="201"} 4
http_request_count{method="DELETE",status_code="204"} 1
http_request_count{method="OPTIONS",status_code="201"} 4
http_request_count{method="GET",status_code="204"} 1
http_request_count{method="PATCH",status_code="201"} 4
http_request_count{method="PUT",status_code="201"} 4
http_request_count{method="DELETE",status_code="203"} 1
http_request_count{method="HEAD",status_code="201"} 4

Integrate endpoints in Prometheus-compatible tools

Now that you’ve structured and exported your Pipe data in Prometheus format, you can integrate it into monitoring and observability tools.

Prometheus is widely supported by various visualization and alerting platforms, making it easy to use your Tinybird data with tools like Grafana, Datadog, and more. See the documentation for these tools to integrate them with the Prometheus endpoints from Tinybird.
