Unlike the other service levels, RHN Monitoring does not include the systems management functions of other entitlements. Instead it is a separate entitlement available to Management- and Provisioning-level customers with Red Hat Enterprise Linux systems.
Monitoring allows an organization to install probes that can immediately detect failures and identify performance degradation before it becomes critical. Used properly, the Monitoring entitlement can give you insight into the applications, services, and devices on each system.
Specifically, Monitoring provides:
Probes — Dozens of probes can be run against each system. These range from simple ping checks to custom remote programs designed to return valuable data.
Notification — Alerts resulting from probes entering WARNING and CRITICAL states can be sent to email and pager addresses with contact methods identified by you. Each probe notification can be sent to a different method, or address.
Central Status — The results of all probes are summarized in a single Probe Status page, with the systems affected broken down by state.
Reporting — By selecting a probe and identifying the particular metric and a range of time, you can generate graphs and event logs depicting precisely how the probe has performed.
