appqoe action

The following operations can be performed on "appqoe action":

add | rm | set | unset | show

add appqoe action

Add a new AppQoE action for triggering

Synopsys

add appqoe action <name> [-priority <priority>] [-respondWith ( ACS | NS ) [<CustomFile>] [-altContentSvcName <string>] [-altContentPath <string>] [-maxConn <positive_integer>] [-delay <usecs>]] [-polqDepth <positive_integer>] [-priqDepth <positive_integer>] [-dosTrigExpression <expression>] [-dosAction ( SimpleResponse | HICResponse )]

Arguments

name

Name for the AppQoE action. Must begin with a letter, number, or the underscore symbol (_). Other characters allowed, after the first character, are the hyphen (-), period (.) hash (#), space ( ), at (@), equals (=), and colon (:) characters. This is a mandatory argument

priority

Priority for queuing the request. If server resources are not available for a request that matches the configured rule, this option specifies a priority for queuing the request until the server resources are available again. If priority is not configured then Lowest priority will be used to queue the request.

Possible values: HIGH, MEDIUM, LOW, LOWEST

respondWith

Responder action to be taken when the threshold is reached. Available settings function as follows:

        ACS - Serve content from an alternative content service

              Threshold : maxConn or delay

        NS - Serve from the NetScaler appliance (built-in response)

             Threshold : maxConn or delay

Possible values: ACS, NS

CustomFile

name of the HTML page object to use as the response

altContentSvcName

Name of the alternative content service to be used in the ACS

altContentPath

Path to the alternative content service to be used in the ACS

polqDepth

Policy queue depth threshold value. When the policy queue size (number of requests queued for the policy binding this action is attached to) increases to the specified polqDepth value, subsequent requests are dropped to the lowest priority level.

Minimum value: 0

Maximum value: 4294967294

priqDepth

Queue depth threshold value per priorirty level. If the queue size (number of requests in the queue of that particular priorirty) on the virtual server to which this policy is bound, increases to the specified qDepth value, subsequent requests are dropped to the lowest priority level.

Minimum value: 0

Maximum value: 4294967294

maxConn

Maximum number of concurrent connections that can be open for requests that matches with rule.

Minimum value: 1

Maximum value: 4294967294

delay

Delay threshold, in microseconds, for requests that match the policy's rule. If the delay statistics gathered for the matching request exceed the specified delay, configured action triggered for that request, if there is no action then requests are dropped to the lowest priority level

Minimum value: 1

Maximum value: 599999999

dosTrigExpression

Optional expression to add second level check to trigger DoS actions. Specifically used for Analytics based DoS response generation

dosAction

DoS Action to take when vserver will be considered under DoS attack and corresponding rule matches. Mandatory if AppQoE actions are to be used for DoS attack prevention.

Possible values: SimpleResponse, HICResponse

rm appqoe action

Removes the specified AppQoE action.

Synopsys

rm appqoe action <name>

Arguments

name
