Know when your site goes down before your users do. Sentry runs automated checks every minute, alerts your team through Slack or email, and links outages to distributed traces so you can debug without switching tools. Manage your site reliability effortlessly Sentry runs HTTP checks on your URLs every minute and catches everything from DNS failures to application errors. An issue only opens after three consecutive failures, so you get real signal rather than noise from transient blips. Check intervals are configurable from one minute to one hour. Set up uptime monitoring Full visibility into system health When a check fails, Sentry surfaces the related traces and errors alongside it. You get a timeline view, the HTTP response details, and a direct path to the spans that were active at the time. Uptime spans are free and do not count against your quota.
