A.8.6. Network Services::POP Mail
The Network Services::POP Mail probe determines if it can connect to the POP3 port on the system. A
port number must be specified; specifying another port number overrides the default port 110. T his
probe collects the following metric:
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. T he 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 CRIT ICAL state.

A.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-T rip Average - The time it takes in milliseconds for the ICMP ECHO packet to travel to and
from the IP address.
Packet Loss - T he 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. T he monitored system directs the ping to a third address,
rather than to the Red Hat Satellite Server. Since the Remote Ping probe tests connectivity from the
monitored system, another IP address must be specified. To conduct pings from the Red Hat Satellite
Server to a system or IP address, use the standard Ping probe instead. See Section A.8.5, “Network
Services::Ping”.
