Remote Service Latency — The time it takes in seconds for the POP server to answer a
connection request.
The required Expect value is the string to be matched against after a successful connection
is made to the POP server. The probe looks for the string in the first line of the response
from the system. The default is +OK. If the expected string is not found, the probe returns
a CRITICAL state.

C.8.7. Network Services::Remote Ping
The Network Services::Remote Ping probe determines if the monitored system can
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, op-
tional 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 C.8.5 Network Services::Ping.
Requirements — The Red Hat Network Monitoring Daemon (
