# Better Stack Uptime Monitors ## Overview Uptime monitors are the core of Better Stack's monitoring platform. They periodically check URLs, ports, or heartbeats to detect downtime and performance degradation. Monitors can be grouped, paused, and configured with custom check intervals, expected status codes, and alerting thresholds. ## Key Concepts ### Monitor Types - **HTTP/HTTPS** - Check a URL for expected status code and response - **Ping (ICMP)** - Ping a host to verify reachability - **TCP** - Check if a TCP port is open and responding - **UDP** - Check UDP port connectivity - **Heartbeat** - Expect periodic check-ins from cron jobs or services - **DNS** - Verify DNS record resolution - **SMTP** - Check mail server connectivity - **POP3/IMAP** - Check email retrieval services ### Monitor Statuses - **Up** - Monitor is healthy, all checks passing - **Down** - Monitor detected downtime - **Paused** - Monitor is paused and not checking - **Pending** - Monitor was just created and hasn't checked yet - **Maintenance** - Monitor is in a maintenance window - **Validating** - Confirming downtime before alerting ### Check Intervals Better Stack supports check intervals from 30 seconds to 24 hours. Common intervals: - **30s** - Critical production services - **60s** - Standard web applications - **180s** - Non-critical services - **300s** - Background or internal services ### Heartbeat Monitors Heartbeat monitors expect periodic pings from your services.
