Uptime Monitoring
How LemWatch checks if your website is online and responding.
Part of Uptime monitoring — the full answer, the facts and the alternatives in one place.
Quick answer
How website uptime monitoring works?
A monitor sends an HTTP request to your URL every 1–5 minutes from multiple regions; if two consecutive checks fail it flags an outage and alerts you.
Uptime Monitoring#
How It Works#
LemWatch sends HTTP requests to your website at regular intervals from multiple locations. If your site returns a non-2xx status code or doesn't respond within 30 seconds, it's marked as potentially down.
Downtime Confirmation#
To prevent false positives from temporary network blips, LemWatch confirms downtime with consecutive failed checks before alerting you. Configure the threshold in Settings → Alert Preferences.
Check Intervals#
| Plan | Interval |
|---|---|
| Free | Every 60 minutes |
| Pro | Every 15 minutes |
| Agency | Every 5 minutes |
| Enterprise | Every 1 minute |
What Gets Checked#
Uptime Percentage#
Calculated over rolling 24h, 7-day, and 30-day windows:
(total_minutes − downtime_minutes) ÷ total_minutes × 100
Maintenance Mode#
When you're doing planned maintenance, enable Maintenance Mode to suppress alerts. See Maintenance Windows for details.
Response Time Tracking#
LemWatch tracks response times over time so you can spot degradation trends before they become outages. A gradually increasing response time often predicts upcoming issues.
