Table A.39. Network Services::IMAP Mail settings
Field Value
IMAP Port* 143
Expect* OK
Timeout* 5
Critical Maximum Remote Service Latency
Warning Maximum Remote Service Latency
A.8.4. Network Services::Mail Transfer (SMTP)
The Network Services::Mail Transfer (SMT P) probe determines if it can connect to the SMTP port on the
system. Specifying an optional port number overrides the default port 25. It collects the following metric:
Remote Service Latency - The time it takes in seconds for the SMT P server to answer a connection
request.

Field Value
SMTP Port* 25

Critical Maximum Remote Service Latency
Warning Maximum Remote Service Latency
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. T his 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 monitored system.
Packet Loss - T he 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 T ranslation (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. T herefore, entering the same IP
address for Ping probes on different systems accomplishes precisely the same task. T o 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”.
