Not all metrics are returned with Prometheus

[singhjoga]

Hi Guys,
I am using APISIX in Standalone mode in Kubernetes. I have enabled Prometheus with below configuration in my config.yaml. I am able to call the /metrics endpoint successfully. However, it returns only the below given metrics. No metrics related my routes and services are returned.

=======config==========
plugin_attr:
      prometheus:
        export_addr:
          ip: 0.0.0
          port: 9092
        prefer_name: true
        export_uri: /metrics

======== metrics returned ===============

# TYPE apisix_nginx_http_current_connections gauge

# TYPE apisix_node_info gauge
apisix_node_info{hostname="apisix-gw-deployment-558499b786-w5ndg"} 1

Any idea what I might be doing wrong?

OK, after reading this article https://apisix.apache.org/blog/2021/11/04/skywalking, I was able to figure out the issue. I had not bound the plugin to the routes. It was not obvious from the plugin page https://apisix.apache.org/docs/apisix/plugins/prometheus.

If you'd like to collect metrics for all the requests, you can bind it to the global rule.

That article is written by @dmsolr, he is one of Apache SkyWalking's PMC members 😄 If you have any questions about APM, we could seek help from @dmsolr.

It was not obvious from the plugin page https://apisix.apache.org/docs/apisix/plugins/prometheus.

Just to make sure, do you mean this part?

PUT /routes
{
    "prometheus": {}
}
