Installation guide

Note
It is recommended that you leave the monitoring configuration values as the default values.
Sendmail needs to be configured to use notifications.
1.2.2. Configuring the Red Hat Network Monitoring Daemon (rhnmd)
To make the most out of your monitoring entitlement, Red Hat suggests installing the Red Hat Network
monitoring daemon on your client systems. Based upon OpenSSH, rhnm d enables the Satellite to
communicate securely with the client system to access internal processes and retrieve probe status.
Please note that the Red Hat Network monitoring daemon requires that monitored systems allow
connections on port 4545. You may avoid opening this port and installing the daemon altogether by
using sshd instead. See Section 1.2.2.2, “Configuring SSH” for details.
Some probes require the daemon. An encrypted connection, either through the Red Hat Network
monitoring daemon or sshd, is required on client systems for the following probes to run:
Linux::CPU Usage
Linux::Disk IO Throughput
Linux::Disk Usage
Linux::Inodes
Linux::Interface Traffic
Linux::Load
Linux::Memory Usage
Linux::Process Counts by State
Linux::Process Count Total
Linux::Process Health
Linux::Process Running
Linux::Swap Usage
Linux::TCP Connections by State
Linux::Users
Linux::Virtual Memory
LogAgent::Log Pattern Match
LogAgent::Log Size
Network Services::Remote Ping
Oracle::Client Connectivity
General::Remote Program
General::Remote Program with Data
Note that all probes in the Linux group have this requirement.
1.2.2.1. Installing the Red Hat Network Monitoring Daemon
Install the Red Hat Network monitoring daemon to prepare systems for monitoring with the probes
identified by rhnm d. Note that the steps in this section are optional if you intend to use sshd to allow
secure connections between the Red Hat Network monitoring infrastructure and the monitored systems.
See Section 1.2.2.2, “Configuring SSH” for instructions.
