Chapter 16: Configure Service Monitors 197
Monitor Type: Select the type of service that you want to monitor.
Timeout: The maximum amount of time that the monitor_agent process
will wait for a probe to complete. For most monitors, the default timeout
interval is five seconds. You can use the default setting or specify a new
timeout interval.
Frequency: The interval of time, in seconds, at which the monitor probes
the designated service. You can use the default setting, typically 30
seconds, or enter a new frequency interval.
Additional parameters: If you are configuring a DNS, HTTP, HTTPS,
NTSERVICE, or CUSTOM monitor, you will be asked for an additional
parameter.
• DNS monitor. Specify the IP address to be resolved. (The monitor
performs reverse lookup.)
• HTTP and HTTPS monitors. Specify the URL for the service. (For the
HTTPS monitor, the URL should begin with HTTPS.) When the
monitor performs its probe operation, it will attempt to retrieve the
URL from the server, giving a higher level of assurance that the
service is functioning correctly. If you do not specify a URL, the probe
operation will connect to the standard Web server port and wait for a
response. If httpd responds, the monitor assumes that the service is
operating correctly.
• NTSERVICE monitor. If you want services dependent on the
monitored NT service to also be started when the NT service is
started, click “Start dependent services.” Then, at the “Start Service
Retry Count” prompt, specify the number of attempts that should be
made.
•
CUSTOM monitor. Type the pathname for the probe script to be used
with the monitor.
When you complete the Add Service Monitor form, the new monitor
appears on the Management Console. In this example, the service
monitor is active on server owl, which provides the active network
interface for the virtual host.
