Optimal Uptime Monitoring Interval
Q1 2026 data from 10K Enterno.io monitors: most popular interval — 5 min (42% of monitors, Free plan), 1 min — 38% (Pro), 30 sec — 12% (Business), 10+ min — 8% (legacy). MTTR (Mean Time To Recover) correlates: 30-sec monitoring detects incidents 3.2× faster than 5-min.
Methodology
Analysis of 10,000+ monitors in Enterno.io for Q1 2026 (10M+ check results). Studied: interval, false-positive rate, time to first detection of real incidents, MTTR.
Interval distribution
| Interval | % monitors | Avg detection time | False-positive rate |
|---|---|---|---|
| 30 sec | 12% | 15 sec | 0.8% |
| 1 min | 38% | 30 sec | 0.3% |
| 5 min | 42% | 2.5 min | 0.1% |
| 10+ min | 8% | 5 min | 0.05% |
Selection guidance
- 30 sec — for mission-critical (banks, fintech, e-commerce > $10K/h revenue). Risk: more false positives.
- 1 min — SaaS standard with > 100 simultaneous active users.
- 5 min — fine for blogs, marketing landings, brochure sites. Saves DB queries.
- 10+ min — only as a backup monitor. Primary should always be ≤ 5 min.
Alert-fatigue trade-off
30-sec monitoring detects faster but on hosts with poor SLA (95-98%) it creates an endless alert stream → alert fatigue → missed real incidents. Fix: set consecutive_fails = 3 (3 consecutive checks down = incident). Kills 80% of transient-glitch alerts while preserving detection for genuine problems.
Multi-region checks
To rule out local network issues, enable checks from 2+ regions. Example: RU-MSK (primary) + EU-DE (backup). Alert only when both locations see down. Available on Enterno.io Pro+ plans.
