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 (

MP

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

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-LinuxConfigure 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)
