Prometheus alerting rules for eBPF, SNMP, WireGuard, Cilium and cert-manager added to awesome-prometheus-alerts

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. -> https://samber.github.io/awesome-prometheus-alerts If you spot anything wrong in the PromQL or have better thresholds for your environment, issues and PRs welcome. submitted by /u/samuelberthe [link] [comments]Technical Information Security Content & DiscussionRead More
