the monitor, you will need to indicate whether dependent services of the NT service
should also be started and stopped.
When the monitored NT service is started, it is provided with four environment
variables that are set as follows:
• COMPUTERNAME = <virtual host IP address>
• _CLUSTER_NETWORK_FQDN_ = <virtual host IP address>.<domain-
name>
• _CLUSTER_NETWORK_HOSTNAME_ = <virtual host IP address>
• _CLUSTER_NETWORK_NAME_ == <virtual host IP address>
The monitor probe queries the status of the NT service. If the status is
SERVICE_RUNNING, the service status remains Up. If the status does not indicate
that the NT service is running, the service status is set to Down.
The NTSERVICE monitor is also available as a device monitor. When deciding
whether to create a service monitor or a device monitor, consider the effect that you
want the monitor to have on the matrix. If you want a single virtual host to be
associated with the monitor, create a service monitor. If you want multiple virtual
hosts, or no virtual hosts, to be associated with the monitor, create a device monitor.
SMTP service monitor
By default, the SMTP service monitor probes TCP port 25 (sendmail port) of the virtual
host address. You can change this port number to the port number configured for
your SMTP server. The default frequency of the probe is every 30 seconds. The default
time that the service monitor waits for a probe to complete is five seconds.
The probe attempts to connect to port 25 and expects to read an initial message
from the SMTP server. This message should begin with 220. If the probe is successful,
the monitor sends the string QUIT\n to the SMTP server. If there are no errors, the
service status remains Up. If an error occurs, the status is set to Down.
TCP service monitor
The generic TCP service monitor defaults to TCP port 0. You will need to set the port
to the listening port of your server software. The default frequency of the probe is
every 30 seconds. The default time that the service monitor waits for a probe to
complete is five seconds. Because the service monitor cannot know what to expect
from the TCP port connection, it simply attempts to connect to the specified port. If
the attempt is successful, the service status remains Up.
