Public Endpoint - StatsD Metrics

This StatsD API endpoint is provided to add additional metrics to AppSignal, where an existing integration can't be used or the language used isn't supported (yet).

This endpoint is meant for integrations that send aggregated metrics over a small period, it's preferred to send one request every 5 seconds with 100 metrics than 100 requests per 5 minutes with one metric each.


Request method: POST

EndpointDescription (Dog)StatsD data

URL parameters

api_keyStringFront-end API key, can be found in App settings.

Body parameters

The post body should contain (Dog)StatsD formatted metrics separated by a newline.

For example:

login_count:1|c|#hostname:frontend1 stripe_api_duration:19|ms|#function:payment,domain:appsignal cpu_usage:55.1|g|#hostname:frontend1,cpu:0

Here is a complete example on how to send these metrics using cURL. (Note the use of single quotes for the --data option and the leading $. Only then will line breaks work in the --data value.)

curl -H "Content-Type: text/plain" -X POST --data $'login_count:10|c|#hostname:frontend1\nstripe_api_duration:19|ms|#function:payment,domain:appsignal' ""

Note: This endpoint is optimized for large amounts of traffic and does not validate the API key or payload, a 200 (OK) response is returned when the body size is within the 200k limit. This doesn't mean the request is accepted when received.
