View System Metrics Graphs
View key metrics for all of your monitored systems
You can use the NGINX Controller Graphs viewer to view key metrics for all of your monitored systems.
- Install the NGINX Controller Agent on instances that you want to monitor
- Configure Metrics collection on your NGINX instances
Take the steps below to view metrics graphs for your individual systems.
- Open the NGINX Controller user interface and log in.
- Select the NGINX Controller menu icon, then select Infrastructure.
- On the Infrastructure menu, select Analytics.
- Select the desired Instance from the list to view its graphs.
The following metrics graphs are displayed for all systems:
- NGINX Connections/s
- NGINX Requests/s
- NGINX Current Connections
- NGINX Current Requests
- NGINX HTTP Errors
- NGINX HTTP Version
- NGINX Workers
- NGINX File Descriptors
- NGINX CPU Usage %
- NGINX Memory Usage
- NGINX Traffic
- NGINX Disk I/O
- NGINX Request Time
- NGINX Disk Buffered
- NGINX Upstream Errors
Some graphs have an additional selector. For example, with “Disk Latency” or “Network Traffic,” you can select the device or interface that you’re analyzing.
Above the graphs, you will find the following:
- Hostname or alias for the selected system
- System properties editor where you can set up an alias for the host, and/or assign host tags
- List of tags assigned to the system
- Time range selector, which helps to display different periods for the graphs
- Time zone selector
You can also copy a predefined graph to a custom dashboard by selecting the graph and clicking the up arrow that appears in the top-right corner of the graph.
See the Metrics and Metadata topic to learn more about the displayed metrics.
