5. On the System Details
⇒
Probes tab, select another notification method and click
Update Probe .

⇒

cation method.
7.5. Probes
Now that the Red Hat Network Monitoring Daemon has been installed and notification
methods have been created, you may begin installing probes on your Monitoring-entitled
systems. If a system is entitled to Monitoring, a Probes tab appears within its System
Details page. This is where you will conduct most probe-related work.
7.5.1. Managing Probes
To add a probe to a system, the system must be entitled to Monitoring. Further, you must
have access to the system itself, either as the system’s root user, through the System Group
Administrator role, or as the Organization Administrator. Then:
1. Log into the RHN website as either an Organization Administrator or the System
Group Administrator for the system.
2. Navigate to the System Details
⇒
Probes tab and click create new probe .
3. On the System Probe Creation page, complete all required fields. First, select the
Probe Command Group. This alters the list of available probes and other fields and
requirements. Refer to Appendix C Probes for the complete list of probes by com-
mand group. Remember that some probes require the Red Hat Network Monitoring
Daemon to be installed on the client system.
4. Select the desired Probe Command and the Monitoring Scout, typically RHN
Monitoring Satellite but possibly an RHN Proxy Server. Enter a brief but
unique description for the probe.
5. Select the Probe Notifications checkbox to receive notifications when the probe
changes state. Use the Probe Check Interval pulldown menu to determine how
often notifications should be sent. Selecting 1 minute (and the Probe Notification
checkbox) means you will receive notifications every minute the probe surpasses its
CRITICAL or WARNING thresholds. Refer to Section 7.4 Notifications to find out
how to create notification methods and acknowledge their messages.
6. Use the RHNMD User and RHNMD Port fields, if they appear, to force the probe to
communicate via
sshd
, rather than the Red Hat Network Monitoring Daemon. Refer
to Section 7.2.3 Configuring SSH for details. Otherwise, accept the default values of
nocpulse and 4545 , respectively.
