Comparing Performance

Use the SQL PI Compare where differences in period activity illustrate underlying performance and monitoring issues. It helps you determine whether a comparison occurrence is an isolated incident or a sign of a potentially significant performance problem.

Compare can be access from the Performance tree.

The comparison can be of whole instances or selected dimension breakdowns (such as user or SQL). Use Compare to address questions such as:

•
What caused a specific activity?
•
What were the resource and load demands of today's instance activity compared with that of a previous day?
•
Is an instance imposing different load levels now than previously?
•
How do we explain the difference in a SQL performance compared with a previous period?
•
What are the differences in program characteristics over two periods that caused different performance?
•
After identifying the different resource usage, you can use compare to identify what caused this difference: Usage pattern? Different SQL behavior? Environmental problem?

The upper panes graphically displays the Workload or any other selected resource.

The middle Activity section displays the dimensions which were significant elements of the difference. Expanding the individual lines displays the dimension members which caused the difference and the composing metrics whose differences exceed the specified threshold.

Use the set of performance related metrics (defined by the chosen resource) to help you explain the difference in resource consumption; for example, a rise in I/O Wait might be explained by a rise in the quantity of physical reads.

Use the Comparison Parameters section in order to enter all the desired information for the cooperation. For example, time range, instance, dimension, time frames, resource.

Reviewing Memory Usage

The Memory drilldown provides access to graphs that display details of memory usage for the currently monitored server.

Viewing the Memory Summary

The Summary panel allows monitoring how the SQL Server instance is using its physical memory. This panel features charts that allow you to perform a full investigation of memory-related issues on the server.

Use this panel to review any possible memory-related performance issues, and then go to the Buffer Cache or Plan Cache panels for an in-depth investigation of such issues.

The Summary panel The Summary panel allows you to perform the tasks described in the following topics:

•
Monitoring Status
•
Investigating Resource Pool Memory Issues
•
Investigating Cached Memory Issues

Monitoring Status

The Status chart displays the main areas used by SQL Server for carrying out database operations within memory. Use these charts to review the efficiency of the memory management, as reflected in the amount of memory allocated to each area.

Memory pressure is defined as the (100-100*Total Server Memory/Target Server Memory) or in other words, 1-accepted memory/requested memory by the SQL server. The percentage division shows the current memory pressure and the amount of memory used or free by SQL Server or entire server memory

Clicking on either of the Machine RAM or the SQL Server metrics allow you to investigate how these values changes over time.

Page Life expectancy is the length of time that a database page will stay in the buffer cache without references. A value too low for your system indicates that pages are being flushed from the buffer pool too quickly. The longer a page can stay in the buffer pool and be read from memory the better.

The Memory Used metric indicates the total percentage of dynamic memory, within the host's physical RAM, that the server is currently consuming.

Alerts regarding memory pressure may indicates that:

•
More RAM Memory is required for the server.
•
The processes running on the SQL server may consume more memory than possible for a healthy server.

The chart at the bottom of this section displays the metrics over time.

Selecting the Configuration Parameters link allows you to view the memory related options on the server.
