We provide the official Grafana dashboard that visualizes the metrics exposed by the NGINX Ingress Controller. The dashboard allows you to filter metrics per Ingress Controller replica or see the metrics from all replicas.

The dashboard has been tested with the following software versions:

• Grafana >= v7.2.0
• Prometheus >= v2.18.1

A Prometheus data source needs to be added before installing the dashboard.

In the Grafana UI complete the following steps:

1. Use the New Dashboard button and click Import.
2. Upload NGINXPlusICDashboard.json or copy and paste the contents of the file in the textbox and click Load.
3. Set the Prometheus data source and click Import.
4. The dashboard will appear. Note how you filter metrics per namespace, per replica name and also per NGINX Plus server zone, server and upstream server (top left corner).

The dashboard comes with 4 rows with the following graphs (the corresponding Prometheus metrics are in parentheses):

• Environment Metrics
  • NGINX Plus Reload (nginx_last_reload_status). This graph shows the state of the last NGINX Plus reload, Successful/Failed.
  • Last Reload Time (nginx_last_reload_milliseconds) graph shows duration of the last reload in milliseconds.
  • Reloads ( nginx_reloads_total). This graph shows the total times NGINX Plus has reloaded.
  • Reload Errors (nginx_reload_errors_total) graph shows the total number of times NGINX Plus has failed to reload.
  • Network I/O (nginxplus_server_zone_received and nginxplus_server_zone_sent). This graphs shows the traffic sent and received by the Ingress Controller.
• Ingress Metrics
  • HTTP Request Volume (nginxplus_http_requests_total). This graphs shows the total number of HTTP requests received by the Ingress Controller.
  • Success Rate Over Time (nginxplus_server_zone_responses). This graph shows all the 1XX, 2XX and 3XX status code responses the Ingress Controller has returned over time.
  • Error Rate Over Time (nginxplus_server_zone_responses). This graph shows all the 4XX and 5XX status code responses the Ingress Controller has returned over time.
  • Ingress Count (ingress_resources_total). The total number of Ingress resources the Ingress Controller is handling at that time.
  • Handled Ingress Resource (ingress_resources_total). This shows the different types of Ingress resources the Ingress Controller is handling, Master, Minion or Regular.
  • Ingress State (nginxplus_up). This shows the current state of the Ingress Controller, up/down.
  • Request Success Rate (nginxplus_server_zone_responses). This graph shows all the non-4XX and 5XX status code responses divided by the total status code responses.
  • Zone Request Volume (nginxplus_server_zone_requests). This graph shows the total HTTP request across all server zones over the last 5 minutes.
• Upstream Metrics
  • Upstream Success Rate (nginxplus_upstream_server_responses). This graph shows all the 1XX, 2XX and 3XX status code responses of upstreams over time.
  • Upstream Error Rate (nginxplus_upstream_server_responses). This graph shows all the 4XX and 5XX status code responses of upstreams over time.
  • Upstream Server Count (nginxplus_upstream_server_state). This graph shows the count for the total number of upstream servers.
  • Upstream Server State (nginxplus_upstream_server_state). This graph shows the current state of the upstream servers.
• SSL
  • SSL Performance (nginxplus_ssl_handshakes, nginxplus_ssl_handshakes_failed). The graph shows the total number of SSL handshakes and the total number of SSL handshakes that failed.
