Deploying AlertSite and creating monitors is intuitive and almost instantaneous. Provide URLs to create availability monitors or use our web recorder DejaClick to create sophisticated transaction monitors. Select browsers, devices and record complex user transactions in real time. Turn the recorded script into monitors and immediately start seeing value.

Find and Fix Issues Before They Impact Your Users 

AlertSite helps you find issues and performance bottlenecks before they impact your users and your business by proactively monitoring your applications at the browser level. In case of failures, AlertSite helps you engage right people at the right time. The reporting data and monitor run history helps you understand how much time was spent for various network activities when loading your application.

Our integration with a leading APM platform helps your trace the application errors at the code level. Such insight helps with root cause analysis and reduces MTTR.

AlertSite's advanced alerting and reporting mechanism helps you get instant actionable insights from your monitoring data. Our alerts are the fastest - sent directly from the monitoring nodes - and the most intelligent - customizable recipients, routing paths and notification methods. AlertSite integrates with leading incident management and operational intelligence platforms to help you resolve issues faster and get real time visibility into business and IT metrics.
