Retention Policies - Dell OpenManage Network Manager Client Manual

The Monitor Status Summary Snap Panel displays the
status of each individual member (Target) of the
monitor, showing the Last Polled time and date, and a
title bar and icon indicating Availability (green is
available, red is not).
Hover the cursor over the Availability icon, and a popup
appears with details about availability. If the device is
available, the RTT (round-trip time) for
communication appears in Avg (average), Max
(maximum), and Min (minimum) amounts, along with
the PacketCount. If it is not, an Error Message appears
instead of the RTT and PacketCount parameters.
To edit more performance settings and targets than are
available here, use the features described in Dashboard Views on page 277. You can create and
display dashboards by right-clicking items in Managed Resources, selecting Show Performance.
Excluding Attributes from Display
The show.perf.exclude property in the portal-ext.properties file contains a comma
delimited list of the attribute display names to exclude from display. Remember, best practice is to
override properties as described in Overriding Properties on page 23.
For example,
show.perf.exclude=CPU Utilization,AvgRTT
If you define this property, the Show Performance command creates charts for the listed attributes.
This has no impact on manually created dashboards.
NOTE:
You must restart tomcat after changing the properties file for the changes to take effect.

Retention Policies

The basis of all reporting and dashboard presentations is retained data from established monitors.
In other words, each monitor provides a simple schema from which you can produce a chart, graph
or report.
