14.8.1 Performance Dashboard overview
The HP Insight Control for Linux web-based Performance Dashboard tool displays actual metric
data in real time for all servers being monitored and managed by HP Insight Control for Linux.
Data is refreshed at one second intervals, and you can dynamically select the metrics you want
to display for the managed servers.
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.
14.8.2 Performance Dashboard features
The Performance Dashboard tool provides the following features:
•
Monitors and displays metrics data for all or user-selected servers 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 server directly from the ring plot
