Circuit

Know It's Down
Before Anyone Else Does.

Circuit deploys lightweight probes across your infrastructure and continuously monitors endpoints, services, and network segments. When something degrades or fails, you know immediately and can trigger automated remediation before users are affected.

Probes That Go Where You Need Them

HTTP, TCP, ICMP, DNS. Circuit supports multiple probe types, each configurable with custom intervals and failure thresholds. Deploy them across services, endpoints, network segments, and cloud resources.

# Circuit probe configuration

probes:
  - name: "api-gateway"
    type: http
    interval: 30s
    threshold: 3 failures

  - name: "db-primary"
    type: tcp
    interval: 15s
    threshold: 1 failure

  - name: "vpn-tunnel"
    type: icmp
    interval: 10s
    threshold: 2 failures

Not Just Up or Down

Circuit tracks baseline performance over time. It catches the things ping checks miss: gradual latency increases, intermittent packet loss, and slow degradation that eventually cascades into outages.

Detection That Triggers Action

Circuit integrates directly with Beacon. When a probe detects a failure, it can automatically trigger remediation: failover services, page on-call, create an incident, and log everything for post-mortem.

# Circuit → Beacon integration

on_failure: cdn-edge
severity: critical

actions:
  - failover_to_backup("cdn-west")
  - alert_oncall(pager=true)
  - create_incident("CDN Edge Down")
  - log_event(audit=true)

Deploy. Baseline. Respond.

Circuit runs continuously inside your infrastructure. The longer it runs, the smarter it gets about what's normal.

1

Deploy Probes

Configure probes for every service, endpoint, and network segment you need to watch. Each runs independently with its own schedule.

2

Learn Baselines

Circuit builds performance baselines over time and flags deviations: latency drift, intermittent failures, and degradation patterns.

3

Act Immediately

Alerts fire instantly. Beacon integrations can trigger automated failovers, incident creation, and notifications before users notice anything is wrong.

Outages Shouldn't Be
a Surprise.

Circuit gives you the early warning system your infrastructure deserves. Runs inside your network. No external dependencies.
