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
sshd
to allow secure connections
between the RHN monitoring infrastructure and the monitored systems. Refer to
Section 7.2.3 Configuring SSH for instructions.
The
rhnmd
package can be found in the RHN Tools channel for all Red Hat Enterprise
Linux distributions. To install it:
1. Subscribe the systems to be monitored to the RHN Tools channel associated with
the system. This can be done individually through the System Details
⇒
Channels
⇒
Software subtab or for multiple systems at once through the Channel Details
⇒
Target Systems tab.
2. Once subscribed, open the Channel Details
⇒
Packages tab and find the
rhnmd
package (under ’R’).
3. Click the package name to open the Package Details page. Go to the Target Systems
tab, select the desired systems, and click Install Packages .
4. Install the SSH public key on all client systems to be monitored, as described in
Section 7.2.4 Installing the SSH key .
5. Start the Red Hat Network Monitoring Daemon on all client systems using the com-
mand:
service rhnmd start
6. When adding probes requiring the daemon, accept the default values for RHNMD
User and RHNMD Port : nocpulse and 4545 , respectively.
7.2.3. Configuring SSH
If you wish to avoid installing the Red Hat Network Monitoring Daemon and opening
port 4545 on client systems, you may configure
sshd
to provide the encrypted connection
