WatchTower — Synthetic Monitoring with AI Root-Cause Analysis
When your site goes down, users usually know before you do — and traditional probes only say "it's down", never why. WatchTower probes from Singapore, Los Angeles and Tokyo, and at the moment of failure automatically captures response headers, traceroutes, DNS resolutions and origin metrics into an evidence chain. A local LLM then turns it into a root-cause report pushed straight to your IM — you see the diagnosis the moment you see the alert.
Core Capabilities
Multi-Region Probing
HTTP / TCP / SSL / DNS checks from UEIC's 4 global nodes (Singapore / LA×2 / Tokyo) at minute-level frequency, with cross-region confirmation to suppress false alarms.
Certificate & Domain Guarding
SSL certificate and domain expiry countdowns with tiered reminders at 30 / 14 / 7 days. Never discover an expired cert half a day late again.
Automatic Evidence Capture
The instant an alert fires: response headers, traceroute, per-region DNS results, origin CPU/memory metrics — the incident scene preserved, not reconstructed from memory.
AI Root-Cause Reports
The evidence chain is fed to a local LLM, producing a structured verdict: DNS, CDN, certificate, origin or network path — with remediation advice attached.
IM Notifications
Telegram / Feishu bots deliver alert and root-cause report in one message, with on-call groups and escalation policies.
Status Page Generation
Generate a public status page in one click and show your customers transparent availability data.
