If you click the Monitoring tab on the top navigation bar, the Monitoring category and links appear. These pages, which require Monitoring entitlements, enable you to view the results of probes you've set to run against Monitoring-entitled systems and manage the configuration of your monitoring infrastructure.
Initiate monitoring of a system through the Probes tab of the System Details page. Refer to Section 6.4.2.6 System Details for a description of the tab. See Appendix C Probes for the complete list of available probes.
As shown in Figure 6-9, the Probe Status page is shown by default when you click Monitoring in the top navigation bar.
The Probe Status page displays the summary count of probes in the various states and provides a simple interface to find problematic probes quickly. Please note the probe totals in the tabs at the top of the page may not match the numbers of probes displayed in the tables below. The counts at the top include probes for all systems in your organization, while the tables display probes on only those systems to which you have access, through the System Group Administrator role. Also, the probe counts displayed here may be out of sync by as much as one minute.
The following list describes each state and identifies the icons associated with them:
— Critical - The probe has crossed a
CRITICAL threshold.
— Warning - The probe has crossed a
WARNING threshold.
— Unknown - The probe is not able to
accurately report metric or state data.
— Pending - The probe has been
scheduled but has not yet run or is unable to run.
— OK - The probe is running successfully.
The Probe Status page contains tabs for each of the possible states, as well as one that lists all probes. The tables are identical in that each contains columns indicating probe state, the system being monitored, the probes used, and the date and time the status was last updated.
In these tables, clicking the name of the system takes you to the Probes tab of the System Details page. Clicking the name of the probe takes you to its Current State page. From there, you may edit the probe, delete it, and generate reports based upon its results.
The probes that have crossed their CRITICAL thresholds or reached a critical status by some other means. For instance, some probes go critical (rather than unknown) when exceeding their timeout period.
The probes that have crossed their WARNING thresholds.
The probes that cannot collect the metrics needed to determine probe state. Most but not all probes enter an unknown state when exceeding their timeout period. This may mean that the timeout should be raised, or the connection cannot be established to the monitored system.
It is also possible the probes' configuration parameters are not correct and their data cannot be found. Finally, this state may indicate a software error has occurred.
The probes whose data have not been received by RHN. This state is expected for a probe that has just been scheduled but has not yet run. If all probes go into a pending state, your monitoring infrastructure may be failing.
The probes that have run successfully without exception. This is the state desired for all probes.
All probes scheduled on systems in your account, listed in alphabetical order by the name of system.
Identifies the selected probe's status and when it last ran, while providing the ability to generate a report on the probe. Although this page is integral to monitoring, it is found under the Probes tab within the System Details page since its configuration is specific to the system being monitored.
To view a report of the probe's results, choose a relevant duration using the date fields and decide whether you would like to see metric data, the state change history or both. To obtain metric data, select the metric(s) you would like to be reported upon, and decide (using the checkboxes) whether the results should be shown in a graph, an error log, or both. Then click Generate report at the bottom of the page. If no data exist for the probe's metrics, you are presented with a message indicating No time series data found for specified time period.
Identifies the contact methods that have been established for your organization. These methods contain email or pager addresses designated to receive alerts from probes.
These methods are created within the Notification
Methods tab of the User Details page. To
see this tab, the user must first be granted the Monitoring Administrator or Organization Administrator role. Clicking the
name of the contact method opens it for editing. Refer to Section 6.8.2.2 User Details — 
for instructions.
Displays the status of your monitoring infrastructure. Anytime you make a change to your monitoring configuration, such as adding a probe to a system or editing a probe's thresholds, you must reconfigure your monitoring infrastructure. Do this by selecting the RHN Server's checkbox and clicking Push Scout Configs. The table on this page identifies the date and time of requested and completed pushes.
Clicking the name of the server opens its RHNMD SSH Public Key.
Collects information that is universally applicable to your Monitoring infrastructure. The most important option available on this page in times of crisis is the Silence All Notifications checkbox. Selecting this will temporarily filter, or suspend, all notifications generated by your Monitoring infrastructure. Uncheck the box when you wish to resume notifications.
Modifying anything on this page will cause the Monitoring services on the RHN Satellite Server to reset, as well as schedule actions for the Monitoring services on all Monitoring-enabled RHN Proxy Servers that connect to this Satellite to be restarted. This is done so that the Monitoring services on these servers will reload their configuration immediately.
Typically, the defaults provided in other fields will do, since they were derived from your Satellite installation. Nevertheless, you may use the fields on this page to alter your Monitoring configuration. For instance, you may change your mail exchange server here. This page also allows you to alter the destination of all administrative emails from the Satellite. When finished, click Update Config.
