In what order are items processed during data collection processing?

Here you may find the information on the way the elements are being collected by MI to be processed by triggers.

Assume you have 10 elements which use external Data Sources and 20 elements which depend on the internal elements. They will be processed depending on the functional criteria, then on multi- or single-threading and finally  on external/internal data sourcing.  The general order of processed elements will be based on the following stages:

 

Stage
Trigger work
1. Datasets
collects data for datasets sourced from sql/plugin
2. Expired Reports
clears stored data for reports with expire settings 
3. Expired external reports
clears stored data for external reports with the following expiresettings http://grabilla.com/0750f-c3f56681-32b7-4f2b-b199-fe24d6c8e1a3.png
4. Calendars collects data for calendars sourced from sql/plugin
5. Elements sourced from dataset collects data for metrics and reports sourced from datasets
6. Elements collects data for metrics/reports sourced from sql/plugin
7. External Images collects images / PDFs for external reports`
8. Composite Metrics collects data for metrics sourced from existing metrics
9. Elements sourced from Existing Reports collects data for metrics/reports sourced from existing reports saved as an sql table
10. History for bulk-fetch dimensioned Metrics collects data for new dimension values that are bulk-fetched for metrics sourced from sql/plugin, and also for those dimensions that are fetched with '%<single-fetch>%' in the data fetch command
11. Change reports collects data for change reports
12. Aggregate Metrics collects data for aggregate metrics
13. Totals for Aggregate Metrics collects data for total dimensions values of aggregate metrics
14. Single Report Metrics collects data for metrics sourced from single reports
15. Totals for Single Report Metrics collects data for total dimension values of metrics sourced from single reports
16. Totals for Metrics collects data for total dimensions values of metrics sourced from sql/plugin/datasets/existing reports/external
17. Composite Reports updates report sourced from existing metrics
18. Totals for Composite Metrics collects data for total dimension values of composite metrics
19. Regeneration queue regenerates charts that are in the queue; this includes updating charts that are affected by group annotations
20. Multi-Metrics regenerates charts for multi-metrics
