20.1 Insight Control for Linux system monitoring overview
Insight Control for Linux provides a complete monitoring environment for administrators focused
on Linux. Insight Control for Linux monitoring combines best-in-class technologies and open source
packages that Linux administrators commonly use. The prominent packages for Insight Control for
Linux monitoring are:
•
Nagios
is a commonly used open source system and network monitoring application
infrastructure. It is a graphical web-based application that provides a variety of system statistics
that you use to monitor the health of
s.
You can configure Nagios to monitor hosts and services that you define. Hosts and services
report data returned through plug-ins. These scripts typically return an ok, warning, or
critical
exit status (0, 1, or 2, respectively) and an informational message on stdout.
If problems occur, Nagios alerts you using predefined methods such as email, SMS, or by
invoking site specific notification tools.
•
Round Robin Database Tool
The Round Robin Database (RRD) Tool is the open source industry standard, high performance
data logging and graphing system for time series data.
•
Supermon
A highly scalable, high-speed monitoring system.
provides all required system
statistics to the Nagios subsystem.
The data that Supermon collects includes system performance sensor and environment data,
such as fan, temperature, and power supply status. This data is collected on a regular basis.
•
syslog
and syslog-ng
The syslog service runs on each managed system and captures log information.
•
Performance Dashboard Tool
The
tool displays metric data refreshed in one-second intervals in a
graphic ring plots.
Insight Control for Linux gathers data using the platform specific management processor,
or
IPMI, as well as OS provided metrics such as load average, nodeinfo, system free space, and so
on. Other information such as syslog alerts is obtained from the /hptc_cluster/adm/logs/
consolidated.log
consolidated log file.
