Real-time job table

Every job across every server in one live grid. Status, timestamps, duration, exit code — all visible at a glance without SSH.

ML-POWERED

Anomaly detection

Learns your baseline. Alerts when a job that normally runs in 2s suddenly takes 40s — before it crosses into failure.

PRECISE

UTC-native timestamps

No timezone confusion. Every timestamp stored and displayed in UTC with millisecond precision across all server locations.

AUDIT-READY

Full year retention

A complete 365-day execution history for every job. Audit trails for compliance, trend analysis, and capacity planning.

Alert
Zero
silent failures on our watch

Configure grace periods down to the second. Set failure tolerance thresholds. Route alerts to the right team member based on on-call rotation — not a shared inbox.

baselines — automatically learned, always current

When a job that normally runs in 1.2s starts taking 40s, you need to know why — not just that it happened. stdout, stderr, exit codes, and runtime histograms in one pane.

billing.charge_subscriptionsexit 0

stdout + stderr capture

Every byte of output stored. Filter by level, search by regex.

Runtime histogram

p50/p95/p99 baselines auto-learned from 30 days of history.

Concurrency guard

Prevent overlapping runs. Detect and kill zombie processes.

Execution replay

Rerun any historical job with the exact same environment.
