• General::Remote Program
• General::Remote Program with Data
Note that all probes in the Linux group have this requirement.
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 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 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 2.4,
“Installing the SSH key” .
5. Start the Red Hat Network Monitoring Daemon on all client systems using the command:
service rhnmd start
6. When adding probes requiring the daemon, accept the default values for RHNMD User and
RHNMD Port:
nocpulse
and
4545
, respectively.
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 required
between the systems and RHN. This may be especially desirable if you already have
sshd
running. To configure the daemon for monitoring use:
1. Ensure the SSH package is installed on the systems to be monitored:
