B Bottleneck scenarios
This appendix provides solutions for some bottleneck scenarios encountered while using Insight
Control performance management.
Analyzing a network storage bottleneck condition
The following sections detail the appropriate responses when a bottleneck condition exists on
network storage.
Selecting the server
To display the Performance Management Online Analysis window for the monitored server, click
the Major icon on All system page.
The screen displays the server tree in the Server Configuration frame and the Status tab in the
Online Analysis pane. The counters that appear in the following figure are selected items from the
various components. The Analysis Explanation indicates that at least one component has a
performance issue. See the following figure:
Server problems can also be seen within the Server Configuration frame. The tree structure in the
Server Configuration frame displays the configuration of each server, including individual
components monitored by performance management. The icons appearing in the tree next to a
server or component indicate the performance status for that item or the item under the server. The
performance status icon for the selected server also appears in the Online Analysis pane. Insight
Control performance management indicates multiple problems for the server in this example.
Generally, only one component has a critical performance issue because bottlenecks tend to mask
one another.
Displaying the storage status
Trace the performance issue by using the information that appears next to the amber (Major) icon.
In the Server Configuration frame, to access the storage information and display the storage status
page in the Online Analysis pane, select Storage. Related and important storage counters appear
