Prometheus alerting rules for eBPF, SNMP, WireGuard, Cilium and cert-manager added to awesome-prometheus-alerts
published on 2026-04-14 13:22:29 UTC by /u/samuelbertheContent:
I maintain awesome-prometheus-alerts, a collection of production-ready Prometheus alerting rules. Just added a batch of rules relevant to low-level system and network monitoring:
eBPF (cloudflare/ebpf_exporter) - Program load failures - Map allocation errors - Decoder config issues
SNMP - Interface operational status - Bandwidth utilization - Interface error/discard rate
WireGuard - Peer last handshake age: fires when a peer hasn't been seen in >3 minutes, which reliably catches dropped tunnels without noisy flapping
Cilium - Policy enforcement drop rate - BPF map pressure - Endpoint health
cert-manager - Certificate expiry warnings - Renewal and ACME failure detection
All rules are plain YAML, no dependencies beyond the respective exporters.

If you spot anything wrong in the PromQL or have better thresholds for your environment, issues and PRs welcome.
