7.2.1. Probes requiring 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.

7.2.2. Installing the Red Hat Network Monitoring Daemon

Install the Red Hat Network Monitoring Daemon to prepare systems for monitoring with the probes
identified in

Section 7.2.1, “Probes requiring the daemon”

. Note that the steps in this section

are optional if you intend to use
