2.1.3 Report function
The report function displays the performance data (records or fields) collected from a monitoring target in the form of easy-to-understand graphs and tables based on settings. For example, one month's worth of CPU usage at a server might be displayed as a line graph.
Report types
The two types of reports are historical reports and real-time reports.
- Historical reports
-
This type of report displays the changes in the data for a monitoring target over a period of time. You create this type of report so that you can analyze trends at the monitoring target.
- Real-time reports
-
This type of report displays the current status of the monitored target. You create this type to check the current status of a monitored item for which a history of performance data is not being collected. You can set such reports to continuously display the most recent data by automatically refreshing at a specified interval.
Approach to the report function
The report function displays the information stored in records and fields as easy-to-understand graphs and tables. Each report is defined as one record.
The following figure shows the relationships among records, fields, and a report using System Overview (historical report) as an example:
