6.4.2.6.8.2. System Details Events Pending

Lists events that are scheduled but have not begun. A prerequisite action is required to complete

successfully before a given action will be attempted. If an action has a prerequisite, there will not

be a checkbox available to cancel that speciﬁc action. Instead, there will be a checkbox next to the

prerequisite action; Cancelling the prerequisite action will cause the action in question to fail.

Actions can be chained in this manner so that action ’a’ requires action ’b’ which requires action ’c’.

Action ’c’ will be the ﬁrst one attempted, and will be the one with the checkbox next to it until it is

completed successfully - if any action in the chain fails, the remaining actions also fail. To unschedule

a pending event, select the event and click the Cancel Events button at the bottom of the page. The

following icons indicate the type of events listed here:

•

— Package Event

• — Errata Event

• — Preferences Event

• — System Event

6.4.2.6.9. System Details Probes —

Displays all of the probes monitoring the system. You must be a Monitoring Administrator or Orga-

nization Administrator to see this tab. The State column shows icons representing the status of each

probe. Refer to Section 6.9 Monitoring —

for descriptions of these states. Clicking the probe de-

scription takes you to its Current State page, while clicking the number in the Edit probe column

allows you to modify the probe’s settings.

To add a probe to the system, click the create new probe link at the top-right corner of the page

and complete the ﬁelds on the following page. Selecting a probe command group changes the list of

available probes and alters the remaining ﬁelds and requirements. Refer to Appendix C Probes for

the complete list of probes by command group. Note that some probes require the Red Hat Network

Monitoring Daemon to be installed on the client system.

Enter a brief but unique description for the probe, select the Scout to run the probe (typically RHN

Monitoring Satellite), and select the Probe Notiﬁcation checkbox to receive alerts. Select a

probe check (or run) interval, complete the remaining ﬁelds, and establish CRITICAL and WARNING

alert thresholds, if this option exists. When ﬁnished, click Create Probe.

Once the probe has been added, you must reconﬁgure your Monitoring infrastructure to recognize it.

Refer to Section 6.9.3 Scout Conﬁg Push —

for details. After the probe has run, its results become

available on the Current State page. Refer to Section 6.9.1.7 Current State — for details.

6.4.3. System Groups —

The System Groups page allows all RHN Management and Provisioning users to view the System

Groups list. Only Organization Administrators may perform the following additional tasks:

1. Create system groups. (Refer to Section 6.4.3.1 Creating Groups.)
