Before attempting to implement RHN Monitoring within your infrastructure, ensure you have all of the necessary tools in place. At a minimum, you need:
Monitoring entitlements — These entitlements are required for all systems that are to be monitored. Monitoring is supported only on Red Hat Enterprise Linux systems.
RHN Satellite Server with Monitoring — Monitoring systems must be connected to a Satellite with a base operating system of Red Hat Enterprise Linux AS 3 Update 5, Red Hat Enterprise Linux AS 4, or later. Refer to the RHN Satellite Server Installation Guide within Help for installation instructions. Contact a Red Hat sales representative to purchase Satellite.
Monitoring Administrator — This role must be granted to users installing probes, creating notification methods, or altering the monitoring infrastructure in any way. (Remember, the Satellite Administrator automatically inherits the abilities of all other roles within an organization and can therefore conduct these tasks.). Assign this role through the User Details page for the user.
Red Hat Network Monitoring Daemon — This daemon, along with the SSH key for the scout, is required on systems that are monitored in order for the internal process monitors to be executed. You may, however, be able to run these probes using the systems' existing SSH daemon (sshd). Refer to Section 7.2, “Red Hat Network Monitoring Daemon (rhnmd)” for installation instructions and a quick list of probes requiring this secure connection. Refer to Appendix C, Probes for the complete list of available probes.
