Starting summarization
There are two ways in which you can start the summarization process:
• Manually
• Automatically (scheduled)
Manually starting summarization
You can manually start the summarization process on the Measurement points selection level. Here, on the action menu, the Summarize readings action is available. The result of this action is split on the Details level into:
• Hourly reading
• Daily readings
• Monthly readings
Scheduling summarization
Typically, it is a good practice to schedule the summarization process on a daily basis, so that only the newly added historical readings of the former day need to be summarized. Summarized data is always available for analyses (through dashboards) until the current day -1 (yesterday).
To schedule summarization, you need to create an action definition in Alerts.
Procedure
1. In Alerts, create an action definition for the Measurement points business object.
2. Add a filter on System status = Active.
3. Select Summarize readings.
4. Set a daily schedule.
Make sure your schedule starts after 12 PM because the processing includes data of the previous day.
5. Specify a start time (preferably outside office hours).
6. Set the action definition to Active.
Repeat these steps for all summarization actions that you want to schedule.
