Uptime monitoring

• HTTP/HTTPS checks against endpoints with configurable intervals, timeouts, and expected status codes.

• Regional or multi-location checks where supported, with latency and availability history.

• Alerting when targets become unreachable or return unexpected responses.

Heartbeat monitoring

• Cron and job-style heartbeats: services report success on a schedule; missed beats raise incidents.

• Grace periods and recovery when jobs resume after transient failures.

SSL monitoring

• Certificate expiry tracking with advance warnings before renewal deadlines.

• Validation of chain and hostname mismatches where applicable.

ICMP / ping monitoring

• Reachability checks via ICMP echo (ping) for hosts and infrastructure that expose ICMP.

• Packet loss and round-trip time trends for network health visibility.

Incident management / Maintenance updates

• Incident lifecycle: open, acknowledge, resolve, with timelines and ownership.

• Correlation of alerts into incidents and post-incident context for outages.

Status pages / boards

• Public or internal status views reflecting current service health and ongoing incidents.

• Historical uptime and incident communication in one place for stakeholders.

• Aggregate public vendor status and incident feeds in one place—see when AWS, GitHub, Datadog, or other dependencies are down without tab-hopping.
