This check monitors the Kubernetes NGINX Ingress Controller . To monitor the F5 NGINX Ingress Controller, set up the Datadog Prometheus integration to monitor desired metrics from the list provided by the NGINX Prometheus Exporter .
The nginx-ingress-controller check is included in the Datadog Agent
package, so you do not need to install anything else on your server.
If your Agent is running on a host, edit the nginx_ingress_controller.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory. See the sample nginx_ingress_controller.d/conf.yaml
for all available configuration options. Then, restart the Agent
.
For containerized environments, see the Autodiscovery Integration Templates for guidance on applying the parameters below.
By default, NGINX metrics are collected by the nginx-ingress-controller check, but for convenience you might want to run the regular nginx check on the ingress controller.
You can achieve this by making the NGINX status page reachable from the Agent. To do this, use the nginx-status-ipv4-whitelist setting on the controller and add Autodiscovery annotations to the controller pod.
For example these annotations, enable both the nginx and nginx-ingress-controller checks and the log collection:
| Parameter | Value |
|---|---|
<INTEGRATION_NAME> | ["nginx","nginx_ingress_controller"] |
<INIT_CONFIG> | [{},{}] |
<INSTANCE_CONFIG> | [{"nginx_status_url": "http://%%host%%:18080/nginx_status"},{"prometheus_url": "http://%%host%%:10254/metrics"}] |
See the sample nginx_ingress_controller.d/conf.yaml for all available configuration options.
Note: For nginx-ingress-controller 0.23.0+ versions, the nginx server listening in port 18080 was removed, it can be restored by adding the following http-snippet to the configuration configmap:
http-snippet: |
server {
listen 18080;
location /nginx_status {
allow all;
stub_status on;
}
location / {
return 404;
}
}
Available for Agent versions >6.0
Collecting logs is disabled by default in the Datadog Agent. To enable it, see Kubernetes log collection .
| Parameter | Value |
|---|---|
<LOG_CONFIG> | [{"service": "controller", "source": "nginx-ingress-controller"}] |
