Monitor associated components

Monitoring data by logically connecting similar component types is important to identify, investigate and
get to the bottom of performance issues.
For example, if your application's response time is high, following is one of the ways to identify the issue
in an array that processes application requests:
1. From the Ports screen, sort the data in the master pane to identify the port that is doing maximum
I/Os.
2. Select that port, from the Actions menu, identify the associated host (Host Groups > Host > Ports).
3. For that host, plot performance graphs of all the LDEVs and identify the LDEV that is contributing to
the observed high response time.
You can view the components that are associated with a specified component record which you select
from the master pane. The components of the same type are grouped together. To view the associated
components and its performance graphs, from the Actions menu, select the associated component type
that you want to view. The associated component page is displayed with a subset of records that are
associated with the main component. For example, the associated components for Host Groups is as
follows: Host Groups > Individual host groups > Ports > Individual Ports > LDEVs > Individual LDEVs.
• Host Groups is the primary component for which you want to view the associated components.
• From the Actions menu, select Ports if you want to view a list of ports that are associated with the
selected Host Group record.
• To view the list of LDEVs associated with that host group, from the Actions menu, select LDEVs.
This logical grouping of components enables easy navigation through different levels of component types
to select and view performance graphs of specific components. In the above example, the ports are
categorized under the host groups. If you notice that the response time of a particular LDEV is high, drill
down to the associated ports to view their performance metrics for the duration when the LDEV response
time is found to be high.
Based on your requirement, select components that belong to different component types under different
categories for multiple XP and XP7 disk arrays, and view their performance graphs for related metrics in
the detail pane.

About Charts

You can plot the performance data for components that belong to the same or different XP and XP7 disk
arrays. Graphical representation of key parameters for components is especially useful when you want to
