8.7. Network Services::Remote Ping
The Network Services::Remote Ping probe determines if the monitored system can
ping
a
specified IP address. It also monitors 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 address. 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 IP address.
• Packet Loss — The percent of data lost in transit.
The IP Address field identifies the precise address to be pinged. Unlike the similar, optional
field in the standard Ping probe, this field is required. The monitored system directs the ping to a
third address, rather than to the RHN Server. Since the Remote Ping probe tests connectivity
from the monitored system, another IP address must be specified. To conduct pings from the
RHN Server to a system or IP address, use the standard Ping probe instead. Refer to
Section 8.5, “Network Services::Ping” .
Requirements — The Red Hat Network Monitoring Daemon (
rhnmd
) must be running on the
monitored system to execute this probe.

8.8. Network Services::RPCService
The Network Services::RPCService probe tests the availability of remote procedure call (RPC)
programs on a given IP address. It collects the following metric:
• Remote Service Latency — The time it takes in seconds for the RPC server to answer a
connection request.
RPC server programs, which provide function calls via that RPC network, register themselves in
