Changing the values for email and pager to reflect the system name enables Nagios to send
notification through the sendmail utility. For example, change
[email protected]
to [email protected].
Nagios can generate a large number of email messages. See Section A.5 (page 261) for information
about how to use the open source Nan utility to control the number of messages Nagios sends.

20.8.1 Performance Dashboard overview
The Insight Control for Linux web-based Performance Dashboard tool displays actual metric data
in real time for the managed systems, that is, servers that Insight Control for Linux monitors and
manages. Data refreshes at one second intervals, and you can dynamically select the metrics you
want to display for the managed systems.
The Performance Dashboard tool receives its data from Supermon and displays the data in the
form of a ring plot, similar to a pie chart.
Running the Performance Dashboard tool slightly affects the system performance of the CMS and
the managed systems.
20.8.2 Performance Dashboard features
The Performance Dashboard tool provides the following features:
•
Monitors and displays metrics data for all or user-selected managed systems in the
icelx_servers
subcollection
•
Reports data for up to 100 systems in a single ring plot
•
Creates multiple ring plots when the hardware configuration has more than 100 systems
•
Offers a large selection of predefined metrics
•
Refreshes metrics data every second
•
Extends monitoring capabilities by launching Nagios directly from the ring plot
•
Provides a quick launch capability, which runs relevant Insight Control for Linux tasks on a
target managed system directly from the ring plot
