Netobserv would continue to work with other CNIs, and CNI-related contributions would continue to be welcomed. There has been a few contributions so far from people using Cilium or Calico, we don't want that to change.

If that happens, technically speaking, we don't expect any major change. Netobserv and ovn-k already have a few integration points, we would just expect to increase the collaboration, and have observability more "baked-in" ovn-k. This is not a call to make ovn-k the exclusive CNI for netobserv.

📣 Hi everyone, We are currently discussing with the maintainers of #ovnkubernetes about the possibility to make netobserv a subproject (in CNCF terms) of ovn-kubernetes. This is still early stage discussions, but we would like to collect feedback from the community about that, if any.

You can work on the #eBPF cache timeout/size to increase aggregation in time, which generates more or less flows. We're changing the defaults. Some tests have shown UP TO 40% CPU DECREASE across all components. It's also less flows to be ingested by Loki. Change: github.com/netobserv/ne...

NetObserv 1.11 for #openshift will be released in a couple of days. FYI, if you use NetObserv already: there's something you might want to look at, without waiting. In some scenarios, tweaking config can result in HUGE performance improvements. 1/2

Oh, that's a nice and long post on #kubevirt written for #vSphere admins who might consider migrating: veducate.co.uk/kubevirt-for... As said, #redhat is well placed here. For those admins looking into #openshift #virtualization , NetObserv can help monitor closely your workloads network.

One more thing, that isn't mentionned in the above article: the recent versions of ovn-kubernetes have a new feature called UDN for User Defined Network, which is basically segmentation. More about that here: developers.redhat.com/articles/202... #redhat #openshift #kubevirt #ovn #kubernetes

- OVN is improving its observability, for instance it can emit events such as when a network policy blocks/accept traffic. NetObserv can leverage and display that. It's only Tech Preview at the moment, so you'll need to wait a bit before having it on a prod cluster.

NetObserv dev @netobserv.bsky.social · 11/03/2025

There are also cool new features related to ovn-kubernetes (you won't get them if you use a different CNI) : - As #OpenShift introduces new User Defined Networks (docs.openshift.com/container-pl...), which offers a much better isolation, NetObserv can visualize them as topologies and more...
