Best Practices and Performance Limits for Flex Insights

Before you begin

before-you-begin page anchor

This guide assumes you have a good understanding of the Flex Insights Data Model.

The performance of reports in your Flex Insights workspace depends on several factors. Some include size of the workspace, frequency and size of data loads, and the complexity of the reports/dashboards in the workspace. These factors could interfere with each other and have a combined impact on the performance of your workspace reports. We recommend the following best practices and performance limits for optimal performance of reporting dashboards in your Flex Insights workspace.

We recommend reviewing the following settings to reduce rendering/execution time of reports in a dashboard:

  • Metric definition. Metrics that have complex calculations or data (facts or attributes) from multiple Data Sets usually take longer to compute. Reducing the number of complex metrics in a report will help in faster execution of the report.
  • Overall load of the workspace. Users rendering the same reports share cached resources and experience better performance. If there are many users accessing different reports, it is difficult for the workspace to leverage caching, impacting performance of the reports. Users accessing fewer reports per dashboard will increase chances of caching and performance of the reports.
  • Data refresh interval. The lower the frequency of data refresh, the faster the report load time will be. This is because every data refresh invalidates caching so the more frequently workspaces are refreshed there will be less caching of reporting data. We recommend keeping the default 60-minute refresh interval as Flex Insights is not designed for real-time monitoring purposes.
  • Size of your Flex Insights workspace. As the size of reporting data in your workspace increases, it adds latency to execution of the reports. This is because the metrics are calculated for a larger duration of reporting data. Report filters and dashboard filters significantly reduce the size of reported data (for example by filtering by a shorter date range).
  • Save dashboard filters. Enabling "Saved Views" lets you save frequently used dashboard filter settings as a named dashboard view. This feature is especially convenient if you need to switch frequently between multiple filter settings.
  • Method of accessing the reports. Rendering reports in the user interface has the highest priority and provides interactive data exploration. Rendering reports via API and sending scheduled emails has lower priority and may take longer.

Dashboard Definition

dashboard-definition page anchor

We have soft limits on the number of dashboards you can define. Staying within these limits ensures good user interface performance.

Dashboards20Maximum number of dashboards in a single workspace
Tabs per dashboard15The maximum number of tabs in a single dashboard
Objects per dashboard tab40The maximum number of all objects (reports, widgets, lines, texts, iframe elements, images. etc.) on a dashboard tab
Reports per dashboard tab20The maximum number of reports (including a single value measure) on a dashboard tab
Filters per dashboard tab8The maximum number of dropdown filters on a dashboard tab

Reports have a limited number of measures and attributes you can use in them. If you need to see more attributes or measures, you can build a dashboard that contains multiple reports on one canvas.

Attributes per report20The maximum number of attributes used in a single report
Measures per report20The maximum number of measures used in a single report
Filters per report20The maximum number of filters used in a single report
Selected values per filter500 for dashboard and

200 for report
The maximum number of attribute values (elements) that can be used in a filter (included or excluded values)

Flex Insights enables you to send CSV reports and PDF dashboards by email to other users in Flex and also to other people in the company that do not have a Flex account.

Scheduled emails2,000The maximum number of scheduled emails
Scheduled email frequency30 minutesThe highest frequency for sending scheduled emails
Recipients per single workspace500The maximum number of people receiving scheduled emails
Scheduled email size14 MBThe maximum size of a scheduled email including all reports included in attachments

We highly recommend using the Flex Insights user interface instead of sending reports by emails. The user interface always shows the latest data and enables users to interact with the data and explore it if they want to do so.

These pertain to limits enforced in Flex Insights Historical Reporting API. You can use the API to export data from any report created from your Flex Insights Analytics Portal(link takes you to an external page).

Total REST API requests per user per 10 seconds1,000The maximum number of REST API requests an authenticated user can generate within 10 seconds
Simultaneously executing REST API requests per user50The maximum number of REST API requests an authenticated user can generate simultaneously
Size of REST API request payload1 MBThe maximum size of the REST API request payload that can be processed
Concurrent connections per IP address100The maximum size of the REST API request payload that can be processed
