NGINX Ingress
Metrics, Dashboards, Alerts and more for NGINX Ingress Integration in Sysdig Monitor.
This integration is enabled by default.
Versions supported: > v1.9.0
This integration is out-of-the-box, so it doesn’t require any exporter.
This integration has 42 metrics.
Timeseries generated: 1500
This integration specifically supports kubernetes/ingress-nginx, and not other NGINX-Ingress versions like nginxinc/kubernetes-ingress.
List of Alerts
| Alert | Description | Format |
|---|---|---|
| [Nginx-Ingress] High Http 4xx Error Rate | Too many HTTP requests with status 4xx (> 5%) | Prometheus |
| [Nginx-Ingress] High Http 5xx Error Rate | Too many HTTP requests with status 5xx (> 5%) | Prometheus |
| [Nginx-Ingress] High Latency | Nginx p99 latency is higher than 10 seconds | Prometheus |
| [Nginx-Ingress] Ingress Certificate Expiry | Nginx Ingress Certificate will expire in less than 14 days | Prometheus |
List of Dashboards
Nginx Ingress
The dashboard provides information on the error rate, resource usage, traffic and certificate expiration of the NGINX ingress.

Monitoring and Troubleshooting NGINX Ingress
This document describes important metrics and queries that you can use to monitor and troubleshoot NGINX Ingress.
Tracking metrics status
You can track NGINX Ingress metrics status with following alerts: Exporter proccess is not serving metrics
# [NGINX Ingress] Exporter Process Down
absent(nginx_ingress_controller_nginx_process_cpu_seconds_total{kube_cluster_name=~$cluster,kube_namespace_name=~$namespace,kube_workload_name=~$workload}) > 0
