 You can access metrics about health and resource usage of the Network Observability Operator from the *Dashboards* page in the web console. A health alert banner that directs you to the dashboard can appear on the *Network Traffic* and *Home* pages in the event that an alert is triggered. Alerts are generated in the following cases:
 
-* The *NetObservLokiError* alert occurs if the `flowlogs-pipeline` workload is dropping flows because of Loki errors, such as if the Loki ingestion rate limit has been reached.
-* The *NetObservNoFlows* alert occurs if no flows are ingested for a certain amount of time..Prerequisites

 * You have the Network Observability Operator installed.
 * You have access to the cluster as a user with the `cluster-admin` role or with view permissions for all projects.

+On the *Overview* tab in the {product-title} console, you can view the overall aggregated metrics of the network traffic flow on the cluster. You can choose to display the information by node, namespace, owner, pod, and service. Filters and display options can further refine the metrics.
 
 In *Observe* -> *Dashboards*, the *Netobserv* dashboard provides a quick overview of the network flows in your {product-title} cluster. You can view distillations of the network traffic metrics in the following categories:
 
- * *Top flow rates per source and destination namespaces (1-min rates)*
- * *Top byte rates emitted per source and destination nodes (1-min rates)*
- * *Top byte rates received per source and destination nodes (1-min rates)*
- * *Top byte rates emitted per source and destination workloads (1-min rates)*
- * *Top byte rates received per source and destination workloads (1-min rates)*
- * *Top packet rates emitted per source and destination workloads (1-min rates)*
- * *Top packet rates received per source and destination workloads (1-min rates)*
+ * *Top byte rates received per source and destination nodes*
+ * *Top byte rates received per source and destination namespaces*
+ * *Top byte rates received per source and destination workloads*
 
+*Infrastructure* and *Application* metrics are shown in a split-view for namespace and workloads. 
 You can configure the `FlowCollector` `spec.processor.metrics` to add or remove metrics by changing the `ignoreTags` list. For more information about available tags, see the xref:../../networking/network_observability/flowcollector-api.adoc#network-observability-flowcollector-api-specifications_network_observability[Flow Collector API Reference]
