Parameters

Parameter	Choices/Defaults	Comments
acctapplicationid string		List of Acct-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. Minimum value = 0 Maximum value = 4294967295
action string	Choices: NONE LOG DOWN	Action to perform when the response to an inline monitor (a monitor of type HTTP-INLINE) indicates that the service is down. A service monitored by an inline monitor is considered DOWN if the response code is not one of the codes that have been specified for the Response Code parameter. Available settings function as follows: * NONE - Do not take any action. However, the show service command and the show lb monitor command indicate the total number of responses that were checked and the number of consecutive error responses received after the last successful probe. * LOG - Log the event in NSLOG or SYSLOG. * DOWN - Mark the service as being down, and then do not direct any traffic to the service until the configured down time has expired. Persistent connections to the service are terminated as soon as the service is marked as DOWN. Also, log the event in NSLOG or SYSLOG.
alertretries string		Number of consecutive probe failures after which the appliance generates an SNMP trap called monProbeFailed. Minimum value = 0 Maximum value = 32
application string		Name of the application used to determine the state of the service. Applicable to monitors of type CITRIX-XML-SERVICE. Minimum length = 1
attribute string		Attribute to evaluate when the LDAP server responds to the query. Success or failure of the monitoring probe depends on whether the attribute exists in the response. Optional. Minimum length = 1
authapplicationid string		List of 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 CER message. Minimum value = 0 Maximum value = 4294967295
basedn string		The base distinguished name of the LDAP service, from where the LDAP server can begin the search for the attributes in the monitoring query. Required for LDAP service monitoring. Minimum length = 1
binddn string		The distinguished name with which an LDAP monitor can perform the Bind operation on the LDAP server. Optional. Applicable to LDAP monitors. Minimum length = 1
customheaders string		Custom header string to include in the monitoring probes.
database string		Name of the database to connect to during authentication. Minimum length = 1
destip string		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 string		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.
deviation string		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. Minimum value = 0 Maximum value = 20939
dispatcherip string		IP address of the dispatcher to which to send the probe.
dispatcherport string		Port number on which the dispatcher listens for the monitoring probe.
domain string		Domain in which the XenDesktop Desktop Delivery Controller (DDC) servers or Web Interface servers are present. Required by CITRIX-XD-DDC and CITRIX-WI-EXTENDED monitors for logging on to the DDC servers and Web Interface servers, respectively.
downtime string		Time duration for which to wait before probing a service that has been marked as DOWN. Expressed in milliseconds, seconds, or minutes. Minimum value = 1 Maximum value = 20939
evalrule string		Default syntax expression that evaluates the database server's response to a MYSQL-ECV or MSSQL-ECV monitoring query. Must produce a Boolean result. The result determines the state of the server. If the expression returns TRUE, the probe succeeds. For example, if you want the appliance to evaluate the error message to determine the state of the server, use the rule MYSQL.RES.ROW(10 .TEXT_ELEM(2).EQ("MySQL")).
failureretries string		Number of retries that must fail, out of the number specified for the Retries parameter, for a service to be marked as DOWN. 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. Minimum value = 0 Maximum value = 32
filename string		Name of a file on the FTP server. The appliance monitors the FTP service by periodically checking the existence of the file on the server. Applicable to FTP-EXTENDED monitors. Minimum length = 1
filter string		Filter criteria for the LDAP query. Optional. Minimum length = 1
firmwarerevision string		Firmware-Revision value for the Capabilities-Exchange-Request (CER) message to use for monitoring Diameter servers.
group string		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. Minimum length = 1
hostipaddress string		Host-IP-Address value for the Capabilities-Exchange-Request (CER) message to use for monitoring Diameter servers.
