NGINX-based Ingress Controller Monitoring

Other recommendations

Wallarm’s version of the Kubernetes Ingress controller is based on the community-supported NGINX Ingress controller for Kubernetes, so the majority of recommendations found in the official Ingress controller documentation and on the public Internet are also applicable to Wallarm’s Ingress controller.

Recommended reading:

The general aspects of NGINX Ingress controller monitoring are already well covered on the Internet. Wallarm provides an additional set of monitoring metrics that should be monitored in a mission-critical environment. The /wallarm-metrics metrics service is disabled by default.

To enable the service, set controller.wallarm.metrics.enabled to true:

controller:
  wallarm:
    metrics:
      enabled: true
