Configuring Probes for Health Monitoring
After you configure a probe, associate single or multiple probes with a server farm. All servers in the
server farm receive probes of the probe types that are associated with that pool.
Note
If you associate a probe of a particular type with a server farm containing real servers that are not
running the corresponding service, the real servers send error messages when they receive a probe of
that type.
To specify a probe type and name, perform this task:
Note
When you specify a probe name and type, it is initially configured with the default values. Enter the
probe configuration commands to change the default configuration.
