A sound monitoring system can help engineers quickly understand the status of services running in production environments and locate problems or give early warning of anomalies when they occur. + +*Prometheus* is a leading open-source project focused on metrics and alerting that has changed the way the world does monitoring and observability. For more information, see *Prometheus*'s official [website](https://prometheus.io/). + +## Begin to access Apache APISIX Prometheus Metrics + +Before starting, please make sure that Apache APISIX (version >= 2.13)and APISIX Ingress controller are installed and working correctly. APISIX uses the `prometheus` plugin to expose metrics and integrate with prometheus but uses `public-api` plugin to enhance its security after version 2.13. For more information, see `public-api` plugin's official [document](https://apisix.apache.org/docs/apisix/plugins/public-api/). + +### Step 1: Enable Prometheus Plugin + +If you need to monitor Apache APISIX simultaneously, you can create the following ApisixClusterConfig resource. + +```yaml +apiVersion: apisix.apache.org/v2beta3 +kind: ApisixClusterConfig +metadata: + name: default +spec: + monitoring: + prometheus: + enable: true +``` + +### Step 2: Enable `public-api` Plugin + +Let's make a basic routing setup, and please note that further configuration should be done based on your local backend service information. The primary solution concept is to use the `public-api` plugin to protect the routes exposed by *Prometheus*. For a more detailed configuration, you can refer to the [example](https://apisix.apache.org/docs/apisix/plugins/public-api/#example) section of the `public-api` plugin. + +```yaml +apiVersion: apisix.apache.org/v2beta3 +kind: ApisixRoute +metadata: + name: prometheus-route +spec: + http: + - name: public-api + match: + hosts: + - test.prometheus.org + paths: + - /apisix/prometheus/metrics + backends: + ## Please notice that there must be your actual "serviceName" and "servicePort" + - serviceName: apisix-admin + servicePort: 9180 + plugins: + - name: public-api + enable: true +``` + +### Step 3: Collect the Metrics + +Now you can then get the indicator parameters by requesting command access. + +```sh +kubectl exec -it -n ${namespace of Apache APISIX} ${Pod name of Apache APISIX} -- curl http://127.0.0.1:9180/apisix/admin/routes -H 'X-API-Key: edd1c9f034335f136f87ad84b625c8f1' + +kubectl exec -it -n ${namespace of Apache APISIX} ${Pod name of Apache APISIX} -- curl http://127.0.0.1:9080/headers -H 'Host: test.prometheus.org' +``` + +Then you will get the metrics you want.
