PRTG Manual: Data Reporting
With Reports you can analyze and review monitoring data for specific time spans. There are several ways to create data reports in PRTG for your individual needs.
To get a report for a single sensor, there is a function included to review historic data in PRTG. It allows you to generate reports and charts for a single sensor's data. See the Historic Data Reports section for more information.
You can use the sophisticated reports machine included in PRTG to create comprehensive and detailed reports for all monitoring data. See the Reports section for more information.
You can also export all monitoring raw data to XML or CSV files and generate your own reports using any third-party software. See the Application Programming Interface (API) Definition section for more information.
You can make monitoring data available to other persons using a special user with read-only rights (see the User Access Rights section), or you can create public or semi-public HTML pages with monitoring data using the Maps feature. See the Maps section for more information.
You can also create custom billing reports based on monitoring data from PRTG, using the open source Billing Tool for PRTG.
