Traditionally, monitoring your network connections required from devices being able to export the flows data. With the rise of software-defined networks, the responsibility of providing observability capabilities relied on the SDN providers or on software-based packet analyzers that often have a noticeable impact on the cluster’s performance.

eBPF is presented as an efficient, non-invasive mechanism to observe different layers of clusters’ network, from L3 to L7, and automatically extract relevant information without having to redeploy neither the network infrastructure nor applications.

Our talk explains the Grafana journey to provide plug and play network and services observability: how we connect to different layers of your services infrastructure to provide from how network packets flow through your system to the details of the L7 service/client requests and responses, and how the low-level network information is matched with Kubernetes metadata for improved user data navigation.
