An update to the node graph is currently in the works, some love is being shown (I work at Grafana Labs).

It's also too bad that they built their own eBPF instrumentation as the Cloudflare eBPF exporter also exists and is very good https://github.com/cloudflare/ebpf_exporter

Alternatively if what you want specifically are the integrations mentioned on the coroot page then my money would be on isovalent and cilium

With ebpf-exporter it is not possible to implement complex logic, such as converting the PID of each TCP connection into a container name and the destination IP into a real IP according to the conntrack table.

This seems like a limitation that could be lifted instead of introducing a separate product (disclaimer: familiar with ebpf exporter but haven’t dug into OP).

Iirc ebpf exporter had some limitations, but they weren’t fundamental. However it was also fairly light, so maybe another tool is just the right solve.

Coroot's agent collects data from various sources to cover all aspects of container behavior. Ebpf-exporter perfectly solves the problem of running custom ebpf programs and turning their output into metrics, but using it as a foundation for more specific solutions doesn't seem reasonable

There's not much to the eBPF profiler they've built, and not very much overlap with ebpf_exporter; ebpf_exporter also seems to require CO-RE kernels.

Are there more data sources or ways to overlay node graph information over time series data?

I’ve wanted to use it, but haven’t had time to write a custom day source.

Some more info there would be fantastic.
