Resource Toolbar Options

The SSAS PI dashboard displays the following components:

•
The Instance View — Provides the ability to investigate and analyze the resource consumption of the instance.
•
The Resource toolbar — By selecting one of the resources, the resource consumptions charts and the overview section are updated to display only the relevant information regarding the activity of the selected resource.

The following resource are available:

•
Workload — Allows you to review the overall workload by gathering all resources into one view.
•
CPU — Allows you to review CPU usage.
•
I/O — Allows you to review the I/O-related data, such as wait time for I/O, reads and writes.
•
Memory — Allows you to review memory related waits and performance data, such as memory used, memory cache size and more.
•
Lock — Allows you to review blocks and deadlocks related information and identify blocked activities.
•
Remote — Allows you to review amount of time activities spent waiting for processing to finish on remote instances such as relational data sources

To review specific data metrics, select one of the specific metrics from the toolbar.

Performance Tree

The performance tree provides iterative (up to three levels) access to any of the key dimensions associated with

Analysis Services activity, based on the OLAP multidimensional model and an instance view of the instance activity. Domain nodes offer a hierarchical view of all types of SSAS activity characteristics. Selecting a dimension from the tree determines what subset of activity is displayed. Iterative drill-downs into domains of interest provides increasingly refined focus and diagnosis.

For example, to begin the investigation by first identifying the most active User, follow the steps described below:

1
Select the Users node, to display the most active users in the selected time range. That is, the users who consumed the highest amount of the selected resource.
2
Select the first user, to focus the entire window on the activity of that user.
3
Identify the most demanding Command that this specific user has executed, by expanding the user node and then selecting the Command dimension node. This displays the most active SQL statements executed by this user.
4
Select a specific Command to focus the entire window on the selected command's activity.
5
Select Client Machines under the selected Command, to view the computers which initiate the command.

In a similar manner, such iterative drilldowns can be carried out into any SSAS dimension of interest, to gain a complete understanding of the causes of its behavior.

The default Analysis Services dimensions are as follows:

•
Commands — The executed MDX, DMX and XMLA commands.
•
Databases — The database context in which the session carried out its operations. A session may switch to numerous databases within its lifetime.
•
Programs — Name of a program that connects to SSAS and executes the Command.
•
Users — Users running the client program.
•
Client Machines — The machines on which the client executable (connected to SQL Server) is running.
•
Command Types — Executed command type (for example, Batch, XMLA, SQL etc).
•
Sessions — Presents the top sessions which consumed the highest active time during the selected time frame.
•
Objects — Displays the top objects that were used by all activities running on the server,their association to other dimensions and the resources they used.

In the Commands dimension there is an option to view information regarding the selected command through the top Commands table top:

•
View Full Text — View full text of the statement\batch selected.

Viewing Historical Metrics

The History section view is divided into two sections that are correlated to each other:

•
Resource consumption charts — This section displays data in five different charts:
•
Workload chart — Displays the instance resource activity over the selected time frame by emphasizing the resources by colors.
•
Breakdown chart — Activity of the instance by second.
•
Resource Breakdown Pie chart — Displays the resource breakdown usage by % of the total instance activity.
•
Overview section — Displays a graphical representation of the metrics highlighted in the Workload related Metrics table.
•
Workload related Metrics — A table that displays a variety of resource consumption metrics which can give an in-depth of the instance activity, each resource holds its default metrics.

Selecting each dimension in the performance tree together with a specific resource effects the data displayed for each Level. For example, by selecting the Lock resource, the Instance view dimension will present only locks related data, the Command dimension will present only the commands that were experiencing locks , Users will show only users that were experiencing locks and so on across all the dimensions and resources.

Viewing Change Tracking

The change tracking tool is an integrated monitoring mechanism. It periodically tracks changes in environments and activity that can potentially influence system performance. Use it to view correlation between occurrences of changes and Analysis Services activity and behavior patterns.

Use the Categories filter mechanism to refine the set of displayed change tracking occurrences. These categories are displayed on the right hand side of the pane and include:

•
MetaData — Report on changes to the Analysis Services server configuration and to the underlying database's schema.
•
System Configuration — Hardware and operating system configuration (for example, disks and network interfaces (NIC), amount of RAM, CPU count, device installations and swap space allocation).
•
User defined — Used for manually documenting user changes that may affect performance. Recording this activity can assist in determining whether a change in performance can be directly associated with this event
