Possible values: ENABLED, DISABLED
deviation
Time value added to the learned average response time in dynamic response time monitoring (DRTM). When a deviation is specified, the appliance learns the average response time of bound services and adds the deviation to the average. The final value is then continually adjusted to accommodate response time variations over time. Specified in milliseconds, seconds, or minutes.

For example, if the Retries parameter is set to 10 and the Failure Retries parameter is set to 6, out of the ten probes sent, at least six probes must fail if the service is to be marked as DOWN. The default value of 0 means that all the retries must fail if the service is to be marked as DOWN.

destIP
IP address of the service to which to send probes. If the parameter is set to 0, the IP address of the server to which the monitor is bound is considered the destination IP address.
destPort
TCP or UDP port to which to send the probe. If the parameter is set to 0, the port number of the service to which the monitor is bound is considered the destination port. For a monitor of type USER, however, the destination port is the port number that is included in the HTTP request sent to the dispatcher. Does not apply to monitors of type PING.
state
State of the monitor. The DISABLED setting disables not only the monitor being configured, but all monitors of the same type, until the parameter is set to ENABLED. If the monitor is bound to a service, the state of the monitor is not taken into account when the state of the service is determined.
Possible values: ENABLED, DISABLED
Default value: ENABLED
reverse
Mark a service as DOWN, instead of UP, when probe criteria are satisfied, and as UP instead of DOWN when probe criteria are not satisfied.
Possible values: YES, NO

Set of IP addresses expected in the monitoring response from the DNS server, if the record type is A or AAAA. Applicable to DNS monitors.
group
Name of a newsgroup available on the NNTP service that is to be monitored. The appliance periodically generates an NNTP query for the name of the newsgroup and evaluates the response. If the newsgroup is found on the server, the service is marked as UP. If the newsgroup does not exist or if the search fails, the service is marked as DOWN. Applicable to NNTP monitors.

vendorSpecificVendorId
Vendor-Id to use in the Vendor-Specific-Application-Id grouped attribute-value pair (AVP) in the monitoring CER message. To specify Auth-Application-Id or Acct-Application-Id in Vendor-Specific-Application-Id, use vendorSpecificAuthApplicationIds or vendorSpecificAcctApplicationIds, respectively. Only one Vendor-Id is supported for all the Vendor-Specific-Application-Id AVPs in a CER monitoring message.

List of Vendor-Specific-Auth-Application-Id attribute value pairs (AVPs) for the Capabilities-Exchange-Request (CER) message to use for monitoring Diameter servers. A maximum of eight of these AVPs are supported in a monitoring message. The specified value is combined with the value of vendorSpecificVendorId to obtain the Vendor-Specific-Application-Id AVP in the CER monitoring message.
vendorSpecificAcctApplicationIds
List of Vendor-Specific-Acct-Application-Id attribute value pairs (AVPs) to use for monitoring Diameter servers. A maximum of eight of these AVPs are supported in a monitoring message. The specified value is combined with the value of vendorSpecificVendorId to obtain the Vendor-Specific-Application-Id AVP in the CER monitoring message.
