Description
Use Case
Dogstatsd allows for events to be published to a StatsD server (typically Datadog Agent) which then is displayed as an Event in Datadog.
https://docs.datadoghq.com/service_management/events/guides/dogstatsd/
In the below PR, inputs.statsd was modified to support parsing the event datagram into a telegraf.Metric.
Expected behavior
An event is published to Datadog.
Actual behavior
No event is published to Datadog.
Additional info
It doesn't look like outputs.datadog supports submitting events. It assumes all data received from the accumulator are metric series and converts them as such. The URL even defaults to https://app.datadoghq.com/api/v1/series, whereas events are submitted to Events API at https://api.datadoghq.com/api/v1/events.
Here is an example event that appears in outputs.datadog:
{
"MetricName": "jdheyburn test event",
"MetricTags": [
{ "Key": "datadog-statsd", "Value": "true" },
{ "Key": "host", "Value": "telegraf-events-0" },
],
"MetricFields": [
{ "Key": "priority", "Value": "normal" },
{ "Key": "alert_type", "Value": "info" },
{ "Key": "text", "Value": "from statsd" }
],
"MetricTime": "2024-11-01T19:59:54.891658849Z",
"MetricType": 3
},
MetricType is telegraf.Untyped. Currently its trying to convert it to a metric and submit it to the series endpoint, whereas it should convert it to an Event and submit it to the correct endpoint.
