HP Insight Control for Linux 6.2 User Guide

19 Configuring monitoring services
This chapter describes how to configure Insight Control for Linux monitoring services. In addition
to an Section 19.1 (page 165), this chapter addresses the following tasks, which you must complete
in this order:
1. “Configuring a self-signed Apache certificate on the CMS” (page 165)
2. “Starting management and monitoring services ” (page 165)
3. “Installing Insight Control for Linux management agents” (page 167)
4. “Verifying successful configuration of the monitoring services” (page 167)
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. For IPMI-based and iLO-based management
processors (MPs), 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 Nagios 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 certificate so there is no need to create
one.
If the CMS 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 Section 25.3 (page 220).
19.3 Starting management and monitoring services
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.
• It also deploys the Insight Control for Linux management agents to all servers in the
{collection_name}_Servers subcollection. For information on managing subcollections,
see Chapter 17 (page 157).
