Uptime monitoring: track website and API availability
✓ Automatic uptime percentage ✓ 24h / 7d / 30d / 90d windows ✓ Full history ✓ Clear reporting
Measure real uptime monitoring for websites, APIs, and background services. UptimeFlux turns probe results into availability stats you can share with stakeholders and customers.
What is uptime?
Uptime is the percentage of time your service responds successfully. 99.9% uptime still allows ~8.76 hours of downtime per year—so monitoring and alerting matter for SLAs and customer trust.
We aggregate successful checks vs total checks across rolling windows (24 hours through 90 days) so you can spot trends, not just incidents.
Pair uptime stats with 24/7 monitoring and instant alerts to shorten mean time to detect and recover.
How uptime is calculated
Uptime equals successful checks divided by total checks in the selected period. Example:
Example: 30 days, one check every 5 minutes
• Total checks: ~8,640
• Successful checks: 8,600
• Uptime = (8,600 / 8,640) × 100 = 99.54%
Dashboards show per-monitor uptime. Add SLA monitoring to track contractual targets and error budgets.
Why monitor uptime?
SLA compliance
Prove availability against commitments with SLA monitoring and historical uptime.
Performance insight
Correlate dips in uptime with latency or dependency issues using history and trends.
Customer communication
Publish transparency on public status pages during incidents.
Proactive detection
Catch failures early with continuous website monitoring before outages dominate your monthly uptime.
