Diagnostic Summary
Latency spike (+380%) began 90s after the 14:30 deploy. Slow-query log shows an unindexed lookup on orders.customer_id introduced in that release.
What to check first
- Roll back the 14:30 deploy or add the missing index
- Compare p95 latency against the 90-day baseline
- Watch eu-west after the fix — confirmation runs automatically
Pattern match: 3 similar incidents in 90 days — all resolved by rollback within 15 minutes.

Intelligence built into every check
Not just uptime pings — Halvyn understands your stack, learns your baselines, and acts before you know there's a problem.
Intelligent Incident Detection
AI-driven anomaly tracking watches latency curves, error rates, and heartbeat cadence simultaneously. Pattern-match across regions detects cascading failures before they breach your SLA.
Smart Analytics & Predictions
AI-driven insights surface root causes, project uptime trends, and expose SSL expiry risks weeks before they become incidents.
Automated Workflows
Instant alert routing via email, Slack, SMS, and phone with on-call escalation policies — one open incident per outage, escalated until resolved.
Multi-Region Confirmation
Before opening an incident, Halvyn cross-checks from a second region. A single flaky probe never wakes your team. If confirmed, the incident opens immediately and your SLA clock starts with full precision.
From reactive to predictive
Halvyn doesn't just tell you when things break — it learns your system's rhythm and warns you before they do.
Continuous Historical Learning
From the first check, Halvyn builds a rolling baseline of your service's latency curves, error rates, and uptime patterns — refined continuously as your traffic changes.
- Rolling 90-day baseline model
- Auto-adapts to traffic changes
- Per-monitor latency percentiles
Intelligent Pattern Recognition
Detects recurring downtime windows by hour-of-day and day-of-week — surfacing whether your Monday 2 AM deploys are the actual culprit before your engineers start guessing.
- Hour-of-day failure heatmap
- Day-of-week risk scoring
- Recurring outage detection
Predictive & Comparative Alerts
Compares your current 7-day failure rate against the 30-day baseline and fires a degradation alert when the trend worsens — before users start filing tickets.
- 7d vs 30d baseline comparison
- Degradation trend alerts
- Smart noise suppression
Every layer of your stack, covered
One platform, no add-ons, no per-host pricing, no surprises.
HTTP & SSL
Status codes, latency, keyword assertions and certificate expiry warnings before your customers notice.
Database monitors
Postgres, MySQL, Redis & Mongo — latency, connection counts and replication lag.
TCP / UDP / Ping / DNS
Every protocol your stack speaks, checked from multiple regions on your schedule.
Heartbeats
Catch cron jobs and background workers that silently stop running.

Incidents & Alerts
Email, Slack & webhooks, SMS and phone calls — with on-call escalations.
One incident per outage.
Escalated until it's fixed.
When a monitor crosses its failure threshold, Halvyn opens exactly one incident — no alert storms. It escalates across channels, then auto-resolves and records the full timeline the moment service recovers.
- Deduplicated — one open incident per monitor
- On-call rotation escalation policies
- Auto-resolve with timeline & post-mortem notes
- One-click acknowledge via email link

One pulse from failure to fixed
Every outage rides the same automated path — no runbook lookups, no manual triage, no forgotten tickets.
Detect
Checks from multiple regions spot the failure and cross-confirm it — a single flaky probe never pages anyone.
Predict
Baseline AI compares live behaviour to your history and flags degradation trends before hard downtime.
Auto-Resolve
One incident per outage. The moment service recovers it closes itself, with the full timeline attached.
Notify
The right person, on the right channel — email, Slack, SMS or voice — escalated until acknowledged.
Every protocol your stack speaks
All monitor types on every plan — from the free tier up.

We watch it
Distributed workers run checks from multiple regions and record latency, uptime and SSL health.
You get alerted
The AI incident engine opens one incident per outage and escalates across your channels until resolved.
Flat price vs. per-host metering
The difference is not the sticker price — it is what happens to it as you add monitors.
| Monitors you run | HalvynFlat | Typical per-host toolMetered |
|---|---|---|
| 10 monitors | $9/moStarter plan | ~$70/mo |
| 50 monitors | $9/moStarter plan | ~$350/mo |
| 200 monitors | $29/moProfessional plan | ~$1,400/mo |
| How it is priced | One flat price per plan | Per host, per check and per feature |
| Monitor types | All 12 types on every plan | Synthetics and database checks cost extra |
| Alert channels | Email, Slack, webhooks, SMS, escalations | Commonly sold as add-ons |
| Next month’s bill | Identical, unless you change plan | Depends on what you added |
Illustrative. The metered column is modelled at $7 per monitor per month, mid-range for per-host and per-check vendors. Real pricing varies by vendor, region and configuration.
Teams sleep better with Halvyn
"We replaced three separate tools with Halvyn and cut our observability spend by 70%. Setup took an afternoon."
"The flat price is the whole pitch. No more per-host math, no more surprise invoices when we scale up checks."
"Heartbeat monitors caught a silently-dead cron the same night we set it up. That alone paid for the year."
Incidents land in Slack before you look up
AI root-cause analysis, one-click acknowledgements, and real-time incident context — all without leaving your workspace.
✅ RESOLVED: api-gateway latency returned to normal. Incident duration: 4m 12s.
🔴 CRITICAL INCIDENT DETECTED
Memory spike on Node-4B
AI Root Cause: Microservice leak detected in API gateway
Suggested Action: Automated rollback recommended
🧠 Root cause confidence: 94% — Memory leak pattern matches API gateway v2.3.1 regression. Rollback to v2.3.0 resolves in ~90s.
AI root cause
Confidence-scored diagnosis posted automatically with every critical alert — no Runbooks needed.
