Red Hat Training

A Red Hat training course is available for Red Hat Satellite

A.8.5. Network Services::Ping

The Network Services::Ping probe determines if the Red Hat Satellite Server can ping the monitored system or a specified IP address. It also checks the packet loss and compares the round trip average against the Warning and Critical threshold levels. The required Packets to send value allows you to control how many ICMP ECHO packets are sent to the system. This probe collects the following metrics:
  • Round-Trip Average - The time it takes in milliseconds for the ICMP ECHO packet to travel to and from the monitored system.
  • Packet Loss - The percent of data lost in transit.
Although optional, the IP Address field can be instrumental in collecting metrics for systems that have multiple IP addresses. For instance, if the system is configured with multiple virtual IP addresses or uses Network Address Translation (NAT) to support internal and external IP addresses, this option may be used to check a secondary IP address rather than the primary address associated with the hostname.
Note that this probe conducts the ping from a Red Hat Satellite Server and not the monitored system. Populating the IP Address field does not test connectivity between the system and the specified IP address but between the Red Hat Satellite Server and the IP address. Therefore, entering the same IP address for Ping probes on different systems accomplishes precisely the same task. To conduct a ping from a monitored system to an individual IP address, use the Remote Ping probe instead. See Section A.8.7, “Network Services::Remote Ping”.
