Figure 150. Performance analysis report
The report presents the bottleneck information first as a summary of the
recommendations, then in a more detailed format. It also has links to the
supporting graphic data. Keep in mind that bottleneck detection and analysis are
complicated. If a monitor seems to be missing in one bottleneck, it may be
because it is contributing to another one.
The report can also be saved to a disk. An x.HTML file is created, where x is the
file name the user specifies when saving. It contains links to the performance
analysis view information, the report information, and the Table view information.
8.7.2 Types of bottlenecks
Bottlenecks are detected when one or more monitors exceed a programmed
threshold setting for an extended period of time. You can adjust these threshold
settings, but the default settings, particularly those that are critical for the integrity
of the performance analysis, are best not changed.
• Bottlenecks
A bottleneck that is currently happening is sometimes called a realized
bottleneck or just a bottleneck. A bottleneck occurs on a system when one or
more devices are constrained.
• Latent bottlenecks
Often when you fix one bottleneck, there will be another waiting to happen, but
it did not occur because the system was slowed down by the first bottleneck. If
one or more of a device's monitors are above the warning threshold while
another device is constrained, it is considered a latent bottleneck.
