Network Observability CLI 1.10 gets a new facelift in this release. While it's still a text-based user interface, you can now use the mouse to interact with the program! It is an `oc` plugin that captures, displays, and saves flows, metrics, or packet information.

Follow the [installation instructions](https://docs.redhat.com/en/documentation/openshift_container_platform/4.20/html/network_observability/network-observability-cli#network-observability-cli-install_netobserv-cli-install) to set this up on your local computer. It runs independent of whether you have Network Observability Operator installed or not.

Before you run the program, it's best to widen your terminal to 100+ characters and 40+ rows for a better display. Then enter `oc netobserv` followed by one of `flows`, `metrics`, or `packets <filter>`. Append `help` to the command to get online help.

Tip: Oftentimes, Network Observability CLI will exit before I am done. To increase the time it runs, add the `--max-bytes` option such as `--max-bytes=500000000` (500 MB). Of course, you will need to have enough disk space to store the temporary data.

To view the metrics, enter `oc netobserv metrics --enable_all` plus any other options to the command. The `--enable_all` is optional and turns on all eBPF features, otherwise many of the graphs will be blank.

In the previous release, you could only see graphs with the OpenShift web console. Now there are text-based graphs!
In the blue box, you can increase or decrease the number of points in the graph by increments of 5, You can also cycle through the different sets of graphs in the **Display** row. If you want the OpenShift web console to display the graphs like before, add the `--background` option.

There is a **Manage panels** button that lets you choose the graphs you want to display (Figure 13). Select or deselect a panel using the Enter key (not the mouse).

In Network Observability, it is easier to create a FlowCollector and FlowMetric instance. It is more secure with the use of network policies. The custom alerts and Network Health Dashboard, while still in Technology Preview, are signs of things to come. As we move beyond insights into analysis, give us feedback on this and other topics on the [discussion board](https://github.com/netobserv/network-observability-operator/discussions).
