Network drops
Stack, queue, driver and hardware counted separately.
What happens in the kernel
Packet drops, OOM, memory stalls and hardware drops grouped by cause.

View by cause
Network drops separate stack, queue, driver and hardware. Memory separates OOM, direct reclaim and stalls. Any probe that fails says why.
Grouped by cause
Memory
OOM, direct reclaim and stalls, aligned to the timeline.
Host hotspots
CPU, locks and syscalls, down to function and process.
Probe status
Which capability works on which host, and why not.
How it works
| Capture | eBPF and kernel probes, enabled per host |
|---|---|
| Compatibility | From 3.10; kernels without BTF use compatibility objects |
| Degradation | A failed probe does not stop the agent; the reason is reported |
| Overhead | Sampling and switches configured per host |
Fits
- Teams tracing host-level performance problems
- Old kernels and domestic distributions
Doesn't fit
- Kernel security policies that forbid loading eBPF programs
- Shared hosts with no root access
