Progress Flowmon Monitoring for Kubernetes Applications
From the perspective of network administrator and operator, the fundamental requirements for network applications are the same regardless of the environment they are running in. They need to have their network communication fast, reliable and secure. To meet these requirements, we need to have relevant data about the application traffic.
For this purpose, the flow data from Progress Flowmon Probes fits greatly with a slight difference in comparison to the flows generated in a standard network. It is necessary to correlate the flow data with particular network applications or services running in Kubernetes (k8s). For this purpose, we use k8s metadata rather than relying on IP addresses, as pods are regularly created and destroyed meaning that the traffic for a specific application can be made up of many different IPs in a short period of time. It's also likely that the same IP address will be associated with multiple applications in a limited period of time.
