Microstrategy Dashboard performance improvements steps

Microstrategy  Dashboard performance improvements steps:

Many times, causes of poor performance can be simplified to specific components.
To troubleshoot performance issues, users must identify these components, then make the appropriate modifications to the environment and/or to the MicroStrategy dashboard to reduce bottlenecks.

Dashboard execution stages can be represented below:

MicroStrategy Intelligence Server

When an end user makes a Document Execution Request through any client (a web browser via MicroStrategy Web, the MicroStrategy Desktop/Developer client, the MicroStrategy Mobile app, or the MicroStrategy Office client), the request is sent to the MicroStrategy Intelligence Server, which processes the request and prepares the response.

The MicroStrategy Intelligence Server will execute all children datasets on the dashboard by either generating SQL and running this against the data warehouse, or by fetching data from a cache. The Intelligence Server will then join all the dataset results into one master table, called the virtual dataset or master dataset, to store in memory. The master dataset includes the union of all attributes in the dataset report, as well as one column for each metric in the document.

After the master dataset has been assembled, the Intelligence Server will retrieve the design structure for the dashboard either by querying the metadata for the dashboard definition, or by fetching the definition from a cache. Subsequently, the Intelligence Server will then generate the appropriate response type for rendering the dashboard. For Office documents, dashboards executed in DHTML view modes, and Flash dashboards, the Intelligence Server will generate XML, and for PDF documents, the Intelligence Server will generate PDF. For Mobile dashboards, the Intelligence Server will generate a binary in addition to XML.

When the response generation is complete, the Intelligence Server will send the response to different components depending on which client the original Document Execution Request was initiated from. For requests made from a web browser via MicroStrategy Web, the MicroStrategy Mobile app, or the MicroStrategy Office client, the Intelligence Server will send the response to the MicroStrategy Web Server, the MicroStrategy Mobile Server, or the MicroStrategy Web Services Server respectively for further processing. For requests made from the MicroStrategy Desktop/Developer client, the Intelligence Server will send the response to the Desktop/Developer client directly without going through an additional server.

MicroStrategy Web Server

End users may render dashboards executed through MicroStrategy Web in DHTML view modes, Flash mode, or PDF. When the MicroStrategy Web Server receives the response from the Intelligence Server for one of these requests, it will transform the Intelligence Server response to the appropriate HTTP response suitable for displaying in the end user browser.

For dashboards executed in DHTML view modes, the Web Server will transform the Intelligence Server XML response to HTML. For Flash dashboards, the Web Server will first upload a Flash dashboard viewer component to the end user browser (called DashboardViewer.swf, by default located here on the Web Server machine: C:\Program Files (x86)\MicroStrategy\Web ASPx\swf\DashboardViewer.swf), then forward the Intelligence Server XML response to the DashboardViewer in order for the end user browser to render. For PDF documents, the Web Server will forward the Intelligence Server PDF response to the end user browser directly.

MicroStrategy Mobile and Web Services Servers

Dashboards executed through the MicroStrategy Mobile app must go through the MicroStrategy Mobile Server, and dashboards executed through the MicroStrategy Office Client must go through the MicroStrategy Web Services server.

For dashboards executed through Mobile, when the MicroStrategy Mobile Server receives the XML and binary response from the Intelligence Server, it will forward this response to the end user mobile client for further processing.

For dashboards executed through Office, when the MicroStrategy Web Services server receives the XML response from the Intelligence Server, it will forward this response to the end user Microsoft Office client for further processing.

The Performance Troubleshooting Cycle

The above chart illustrates the Performance Troubleshooting Cycle. The goal of the cycle is to improve performance by identifying which components are acting as bottlenecks, then making the appropriate modifications to these components specifically, the environment as a whole, or the dashboard itself.

Monitoring

The first step of the cycle is to quantify the performance by measuring the time spent in each of the components that are part of a Document Execution Request, as described in the preceding sections. The table below summarizes a few key modules that commonly consume the most amount of time during a dashboard execution:

MicroStrategy Component	Key Module
Intelligence Server	Query Execution
	Data Preparation
	XML generation
Web Server	Web processes
	Network
Client	Client rendering

To measure the time spent in these components, refer to the following resources:

• Data Preparation and XML Generation - KB30914: Overview of Profiling MicroStrategy Documents

Web Server

• Web processes - KB10211: What are MicroStrategy Web statistics and how can they be activated?

Client

• Client rendering - KB30914: Overview of Profiling MicroStrategy Documents

Optimizing

After bottlenecks have been identified, certain component-level settings can be adjusted to optimize performance. However, since MicroStrategy deployments will typically rely on third-party components, several component-level settings may be outside the scope of MicroStrategy Technical Support but will nonetheless effect MicroStrategy performance. An example of this is an Intelligence Server may perform slowler on a machine with relatively fewer hardware resources (RAM, CPU speed, disk read/write speed, etc.) than a machine with more resources. As another example, an Intelligence Server may also perform slower on a machine with plentiful resources but many other processes running simultaneously in the background compared to a machine dedicated for just the Intelligence Server process. As a final example, an Intelligence Server and a Web Server may generate a document body quickly but a client browser may not be powerful enough to render this document in a short time period.
