 * [metric alerts](./alerts-log.md) are set by you and can monitor a wide range of metrics such as CPU occupancy, request rates,  page load times, and so on. You can use them to warn you, for example, if you need to add more resources. By contrast, Smart Detection of Failure Anomalies covers a small range of critical metrics (currently only failed request rate), designed to notify you in near real-time manner once your web app's failed request rate increases compared to web app's normal behavior. Unlike metric alerts, Smart Detection automatically sets and updates thresholds in response changes in the behavior. Smart Detection also starts the diagnostic work for you, saving you time in resolving issues.
 
-* [Smart Detection of performance anomalies](proactive-performance-diagnostics.md) also uses machine intelligence to discover unusual patterns in your metrics, and no configuration by you is required. But unlike Smart Detection of Failure Anomalies, the purpose of Smart  Detection of performance anomalies is to find segments of your usage manifold that might be badly served - for example, by specific pages on a specific type of browser. The analysis is performed daily, and if any result is found, it's likely to be much less urgent than an alert. By contrast, the analysis for Failure Anomalies is performed continuously on incoming application data, and you will be notified within minutes if server failure rates are greater than expected.

-Application Insights finds performance issues that might only affect some portion of your users, or only affect users in some cases. For example, if a page loads slower on a specific browser types compared to others,  or if a particular server handles requests more slowly than other servers. It can also discover problems that are associated with combinations of properties, such as slow page loads in one geographical area for clients using particular operating system.

 Anomalies like these are hard to detect just by inspecting the data, but are more common than you might think. Often they only surface when your customers complain. By that time, it's too late: the affected users are already switching to your competitors!
 
 Currently, our algorithms look at page load times, request response times at the server, and dependency response times.  
 
 You don't have to set any thresholds or configure rules. Machine learning and data mining algorithms are used to detect abnormal patterns.
