Must begin with an ASCII alphanumeric or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Minimum length = 1 .PARAMETER Type Type of monitor that you want to create. Possible values = PING, TCP, HTTP, TCP-ECV, HTTP-ECV, UDP-ECV, DNS, FTP, LDNS-PING, LDNS-TCP, LDNS-DNS, RADIUS, USER, HTTP-INLINE, SIP-UDP, LOAD, FTP-EXTENDED, SMTP, SNMP, NNTP, MYSQL, MYSQL-ECV, MSSQL-ECV, ORACLE-ECV, LDAP, POP3, CITRIX-XML-SERVICE, CITRIX-WEB-INTERFACE, DNS-TCP, RTSP, ARP, CITRIX-AG, CITRIX-AAC-LOGINPAGE, CITRIX-AAC-LAS, CITRIX-XD-DDC, ND6, CITRIX-WI-EXTENDED, DIAMETER, RADIUS_ACCOUNTING, STOREFRONT, APPC, CITRIX-XNC-ECV, CITRIX-XDM .PARAMETER Interval Time interval between two successive probes. Must be greater than the value of Response Time-out. Default value: 5 Minimum value = 1 Maximum value = 20940000 .PARAMETER IntervalType Monitor interval units. Default value: SEC Possible values = SEC, MSEC, MIN .PARAMETER DestinationIP 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. .PARAMETER DestinationPort 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. .PARAMETER ResponseTimeout Amount of time for which the appliance must wait before it marks a probe as FAILED. .PARAMETER ResponseTimeoutType Amount of time for which the appliance must wait before it marks a probe as FAILED. Must be less than the value specified for the Interval parameter. Note: For UDP-ECV monitors for which a receive string is not configured, response timeout does not apply. For UDP-ECV monitors with no receive string, probe failure is indicated by an ICMP port unreachable error received from the service. Default value: 2 Minimum value = 1 Maximum value = 20939000 .PARAMETER Downtime Time duration for which to wait before probing a service that has been marked as DOWN. .PARAMETER DowntimeType Time duration for which to wait before probing a service that has been marked as DOWN. Expressed in milliseconds, seconds, or minutes. Default value: 30 Minimum value = 1 Maximum value = 20939000 .PARAMETER 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. Minimum value = 0 Maximum value = 20939000 .PARAMETER Retries Maximum number of probes to send to establish the state of a service for which a monitoring probe failed. Default value: 3 Minimum value = 1 Maximum value = 127 .PARAMETER ResponseTimeoutThreshold Response time threshold, specified as a percentage of the Response Time-out parameter. If the response to a monitor probe has not arrived when the threshold is reached, the appliance generates an SNMP trap called monRespTimeoutAboveThresh. After the response time returns to a value below the threshold, the appliance generates a monRespTimeoutBelowThresh SNMP trap. For the traps to be generated, the "MONITOR-RTO-THRESHOLD" alarm must also be enabled. Minimum value = 0 Maximum value = 100 .PARAMETER AlertRetries Number of consecutive probe failures after which the appliance generates an SNMP trap called monProbeFailed. Minimum value = 0 Maximum value = 32 .PARAMETER SuccessRetries Number of consecutive successful probes required to transition a service's state from DOWN to UP. Default value: 1 Minimum value = 1 Maximum value = 32 .PARAMETER FailureRetries 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 .PARAMETER NetProfile Name of the network profile. Minimum length = 1 Maximum length = 127 .PARAMETER TOS Probe the service by encoding the destination IP address in the IP TOS (6) bits. Possible values = YES, NO .PARAMETER TOSID The TOS ID of the specified destination IP. Applicable only when the TOS parameter is set. Minimum value = 1 Maximum value = 63 .PARAMETER 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. Default value: ENABLED Possible values = ENABLED, DISABLED .PARAMETER 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. Default value: NO Possible values = YES, NO .PARAMETER Transparent The monitor is bound to a transparent device such as a firewall or router. The state of a transparent device depends on the responsiveness of the services behind it. If a transparent device is being monitored, a destination IP address must be specified. The probe is sent to the specified IP address by using the MAC address of the transparent device. Default value: NO Possible values = YES, NO .PARAMETER LRTM Calculate the least response times for bound services. If this parameter is not enabled, the appliance does not learn the response times of the bound services. Also used for LRTM load balancing. Possible values = ENABLED, DISABLED .PARAMETER Secure Use a secure SSL connection when monitoring a service. Applicable only to TCP based monitors. The secure option cannot be used with a CITRIX-AG monitor, because a CITRIX-AG monitor uses a secure connection by default. Default value: NO Possible values = YES, NO .PARAMETER IPTunnel Send the monitoring probe to the service through an IP tunnel. A destination IP address must be specified. Default value: NO Possible values = YES, NO .PARAMETER ScriptName Path and name of the script to execute. The script must be available on the NetScaler appliance, in the /nsconfig/monitors/ directory. Minimum length = 1 .PARAMETER DispatcherIP IP address of the dispatcher to which to send the probe. .PARAMETER DispatcherPort IP address of the dispatcher to which to send the probe. .PARAMETER ScriptArgs String of arguments for the script. The string is copied verbatim into the request. .PARAMETER CustomProperty Send additional monitor-specific properties when creating the monitor. Example STOREFRONT monitor value: @{ StoreName = 'Store' } .PARAMETER ResponseCode Response codes for which to mark the service as UP .PARAMETER HTTPRequest HTTP request to send to the server (for example, "HEAD /file.html"). .PARAMETER Passthru Return the load balancer monitor object. #> [cmdletbinding(SupportsShouldProcess = $true, ConfirmImpact='Low')] param( $Session = $script:session, [parameter(Mandatory = $true)] [string[]]$Name = (Read-Host -Prompt 'Monitor name'), [ValidateSet('PING', 'TCP', 'HTTP', 'TCP-ECV', 'HTTP-ECV', 'UDP-ECV', 'DNS', 'FTP', 'LDNS-PING', 'LDNS-TCP', 'RADIUS', 'USER', 'HTTP-INLINE', 'SIP-UDP', 'LOAD', 'FTP-EXTENDED', 'SMTP', 'SNMP', 'NNTP', 'MYSQL', 'MYSQL-ECV', 'MSSQL-ECV', 'ORACLE-ECV', 'LDAP', 'POP3', 'CITRIX-XML-SERVICE', 'CITRIX-WEB-INTERFACE', 'DNS-TCP', 'RTSP', 'ARP', 'CITRIX-AG', 'CITRIX-AAC-LOGINPAGE', 'CITRIX-AAC-LAS', 'CITRIX-XD-DDC', 'ND6', 'CITRIX-WI-EXTENDED', 'DIAMETER', 'RADIUS_ACCOUNTING', 'STOREFRONT')] [string]$Type = 'PING', [ValidateRange(1, 20940000)] [int]$Interval = 5, [ValidateSet('SEC', 'MSEC', 'MIN')] [string]$IntervalType = 'SEC', [ValidateScript({$_ -match [IPAddress]$_ })] [string]$DestinationIP, [int]$DestinationPort, [ValidateRange(1, 20939000)] [int]$ResponseTimeout = 2, [ValidateSet('SEC', 'MSEC', 'MIN')] [string]$ResponseTimeoutType = 'SEC', [ValidateRange(1, 20939000)] [int]$Downtime = 30, [ValidateSet('SEC', 'MSEC', 'MIN')] [string]$DowntimeType = 'SEC', [ValidateRange(0, 20939000)] [int]$Deviation, [ValidateRange(1, 127)] [int]$Retries = 3, [ValidateRange(0, 100)] [int]$ResponseTimeoutThreshold, [ValidateRange(0, 32)] [int]$AlertRetries, [ValidateRange(0, 32)] [int]$SuccessRetries = 1, [ValidateRange(0, 32)] [int]$FailureRetries, [ValidateRange(1, 127)] [string]$NetProfile, [ValidateSet('YES', 'NO')] [string]$TOS = 'NO', [ValidateRange(1, 63)] [int]$TOSID, [ValidateSet('ENABLED', 'DISABLED')] [string]$State = 'ENABLED', [ValidateSet('Yes', 'NO')] [string]$Reverse = 'NO', [ValidateSet('YES', 'NO')] [string]$Transparent = 'NO', [ValidateSet('ENABLED', 'DISABLED')] [string]$LRTM = 'DISABLED', [ValidateSet('YES', 'NO')] [string]$Secure = 'NO', [ValidateSet('YES', 'NO')] [string]$IPTunnel = 'NO', [string]$ScriptName, [ValidateScript({$_ -match [IPAddress]$_ })] [string]$DispatcherIP, [int]$DispatcherPort, [string]$ScriptArgs, [System.Collections.Hashtable]$CustomProperty, [switch]$PassThru, [Parameter()] [string[]] $ResponseCode, [Parameter()] [string] $HTTPRequest ) begin { _AssertSessionActive } process { foreach ($item in $Name) { if ($PSCmdlet.ShouldProcess($item, 'Create Server')) { try { $params = @{ monitorname = $item type = $Type interval = $Interval units3 = $IntervalType resptimeout = $ResponseTimeout units4 = $ResponseTimeoutType downtime = $Downtime units2 = $DowntimeType retries = $Retries successretries = $SuccessRetries tos = $TOS state = $State reverse = $Reverse transparent = $Transparent lrtm = $LRTM secure = $Secure iptunnel = $IPTunnel } if ($PSBoundParameters.ContainsKey('DestinationIP')) { $params.Add('destip', $DestinationIP) } if ($PSBoundParameters.ContainsKey('DestinationPort')) { $params.Add('destport', $DestinationPort) } if ($PSBoundParameters.ContainsKey('Deviation')) { $params.Add('deviation', $Deviation) } if ($PSBoundParameters.ContainsKey('ResponseTimeoutThreshold')) { $params.Add('resptimeoutthresh', $ResponseTimeoutThreshold) } if ($PSBoundParameters.ContainsKey('AlertRetries')) { $params.Add('alertretries', $AlertRetries) } if ($PSBoundParameters.ContainsKey('FailureRetries')) { $params.Add('failureretries', $FailureRetries) } if ($PSBoundParameters.ContainsKey('NetProfile')) { $params.Add('netprofile', $NetProfile) } if ($PSBoundParameters.ContainsKey('TOSID')) { $params.Add('tosid', $TOSID) } if ($PSBoundParameters.ContainsKey('ScriptName')) { $params.Add('scriptname', $ScriptName) } if ($PSBoundParameters.ContainsKey('DispatcherIP')) { $params.Add('dispatcherip', $DispatcherIP) } if ($PSBoundParameters.ContainsKey('ScriptArgs')) { $params.Add('scriptargs', $ScriptArgs) } if ($PSBoundParameters.ContainsKey('CustomProperty')) { ## Add each custom property to the $params Hashtable foreach ($key in $CustomProperty.Keys) { $params.Add($key.ToLower(), $CustomProperty[$key]) } } if ($PSBoundParameters.ContainsKey('ResponseCode')) { $params.Add('respcode', $ResponseCode) } if ($PSBoundParameters.ContainsKey('HTTPRequest')) { $params.Add('httprequest', $HTTPRequest) } _InvokeNSRestApi -Session $Session -Method POST -Type lbmonitor -Payload $params -Action add if ($PSBoundParameters.ContainsKey('PassThru')) { return Get-NSLBMonitor -Session $session -Name $item } } catch { throw $_ } } } } } |
