Splunk Observability Cloud

Splunk Observability Cloud and Kong plugin setup?


I'm trying to get the kong plugin to work with Splunk Observability cloud.

Here is my agent_config.yaml relating to kong:



  type: collectd/kong
  port: 8000

   receivers: [hostmetrics, otlp, signalfx, smartagent/signalfx-forwarder, smartagent/kong]



When I start my Splunk OTEL collector I am getting metrics from the server but not the Kong service, checking journalctl I see:



otelcol[25528]: 2023-01-30T17:08:05.855Z        error        signalfx/handler.go:189        Traceback (most recent call last):

I have installed the kong plugin using these instructions:

The signalfx Kong plugin was written for Kong 2.x. I don't believe it is compatible with Kong 3.x. This may be the problem if you have the newest version of Kong. Kong 3.x deprecated a bunch of lua libraries the plugin was using.
