C.10. RHN Satellite Server

The probes in this section may be applied to the RHN Satellite Server itself to monitor its health and performance. Since these probes run locally, no specific application or transport protocols are required.

C.10.1. RHN Satellite Server::Check Alive

The RHN Satellite Server::Check Alive probe is useful in ensuring the viability of your Monitoring-enabled Satellite. It reports the following metrics:

If monitoring is critical to your infrastructure, consider setting the probe to run every five minutes, alert after a single failure, and renotify after 10 minutes to ensure this probe functions optimally.
