Site24x7 Real User Monitoring (RUM) now allows you to get data for custom time periods. You can choose to view RUM metrics from last 1 hour to last 30 days, data for a specific date and time can also be viewed.
Viewing RUM metrics for a custom date or over a range of dates enables you to identify the gradual performance changes in your application, say an increase or decrease in application response time. This is also helpful in identifying the bottlenecks during any significant application problems. Additionally, you can also mark your important feature updates with milestone marker and track them at a later date, in case of issues.
