19 Configuring monitoring services
This chapter describes how to configure Insight Control for Linux monitoring services. In addition
to an
, this chapter addresses the following tasks, which you must complete
in this order:
1.
“Configuring a self-signed Apache certificate on the CMS” (page 154)
2.
“Starting management and monitoring services ” (page 154)
3.
“Installing Insight Control for Linux management agents” (page 156)
4.
“Verifying successful configuration of the monitoring services” (page 156)
19.1 Overview of monitoring
The monitoring services that Insight Control for Linux provides consider a wide array of metrics to
understand the health and status of a remote host. All these metrics are periodically archived for
historical analysis. These metrics include CPU usage, memory usage, load averages, swap, and
many others.
Insight Control for Linux also monitors the hardware sensors of remote hosts if they have a supported
management processor, such as an iLO 3 or an iLO 4. For IPMI-based and iLO-based management
processors (
s), credentials must be supplied to log into them. These credentials and the response
from the MP are sent encrypted over the network through an SSL channel.
19.2 Configuring a self-signed Apache certificate on the CMS
The
monitoring tool in Insight Control for Linux requires a secure configuration for the
Apache web server.
RHEL Version 5 is shipped with an Apache self-signed
so there is no need to create one.
If the
does not already have a self-signed certificate, follow these steps:
1.
Create the certificate:
# /opt/hptc/config/sbin/create_apache_certificate gconfigure
If you need assistance answering the certificate configuration questions, see the req(1) and
openssl(1) man pages for more information.
2.
Restart the Apache service:
•
For SLES, run the following commands:
# /etc/init.d/apache2 stop
# /etc/init.d/apache2 startssl
•
For RHEL Version 4, run the following commands:
# /etc/init.d/httpd stop
# /etc/init.d/httpd start
If you encounter problems starting the Apache service, see
.
19.3 Starting management and monitoring services
This task configures the target server or servers with advanced monitoring and management features
such as Nagios and Performance Dashboard.
The Options
→IC-Linux→Configure Management Services menu item performs the following
operations:
•
It populates the Insight Control for Linux collection.
•
It configures and starts the management and monitoring services.
