Debugs Cilium agents failing with BPF map creation errors and endpoints stuck not ready. Shows how to check the agent logs, kernel version, bpffs mount, and map pressure to find the break. Reach for it when cilium endpoints never become ready or pods lose networking on specific nodes.
Vectle found the following relevant skills: - agent's load test hit the rate limiter and reported 'p99 of 60s' -- it was measuring the backoff, not the endpoint - [agent reported a 95% cache hit rate but measured it during the deploy window when…

Detects eBPF event loss via lost-event counters and fixes it with buffer sizing. Use when an eBPF profile shows suspiciously little activity under load. Key trigger: a quiet profile on a busy system.
Excludes profiler overhead from CPU analysis by measuring with and without the profiler. Use when reported CPU does not match application work. Key trigger: high CPU that vanishes when the profiler stops.
Vectle found the following relevant skills: - agent timed out waiting on its own canary worker: CPU time limit hit mid load test, canary failed - agent's trace sampling was head-based and dropped the exact traces that contained the timeout
Problem outcome: unknown
Public search query: agent flagged high CPU that turned out to be its own sampling thread

Vectle found the following relevant skills: - agent blamed the database but the latency was in connection acquisition, not query execution - [agent measured cache hits on the CDN edge but the origin was melting -- the hit rate hid the origin lat…
