This parameter specifies the name of the Vserver on which you want to modify an FPolicy external engine.

This parameter specifies the name of the FPolicy external engine that you want to modify. An external engine name can be up to 256 characters long. An external engine name is a string that can only contain any combination of ASCII-range alphanumeric characters (a-z, A-Z, 0-9), "_", and "." .

This parameter specifies a list of IP addresses for the primary FPolicy servers to which you want the external engine you modify to apply. The -primary-servers parameter is used to specify a list of servers to which to send file access events for a given FPolicy policy. When an administrator configures multiple servers as primary servers, notifications are sent to the FPolicy servers in a round-robin fashion.

This parameter specifies the port number for the FPolicy service.

This parameter specifies a list of IP addresses for the secondary FPolicy servers to which you want the external engine you modify to apply. Secondary servers will be used only when all the primary servers are not reachable. When an administrator configures multiple servers as secondary servers, notifications are sent to FPolicy server in a round-robin fashion. By default, no secondary server is selected.

This parameter specifies the type of the external engine. This specifies how the FPolicy server should behave, synchronously or asynchronously. By default, it is synchronous in nature. When set to synchronous, after sending a notification to the external FPolicy server, request processing does not continue until after receiving a response from the FPolicy server. At that point request flow either continues or processing results in denial, depending on whether the response from the FPolicy server permits the requested action. When set to asynchronous, after sending a notification to the external FPolicy server, file request processing continues.

This parameter specifies the SSL option for external communication with the FPolicy server. Possible values include the following:

This parameter specifies the timeout for canceling a request. It is used to specify the time interval in which the node waits for a response from the FPolicy server. Beyond this timeout, a cancel request is sent to the FPolicy server to cancel the pending request. The request is then sent to an alternate FPolicy server that is registered for the policy. This timeout helps in handling a FPolicy server that is not responding, which can improve CIFS/NFS client response. Also, this feature can help in releasing of system resources since the request is moved from a down/bad FPolicy server to an alternate FPolicy server. The value for this field must be between 0s and 100s. By default, it is 20s.

This parameter specifies the timeout for aborting a request. The value for this field must be between 0s and 200s. By default, it is 40s.

This parameter specifies the interval for sending status requests. It is used to specify the interval after which a status request will be send to the FPolicy server. The value for this field must be between 0s and 50s. By default, it is 10s.

This parameter specifies the maximum number of attempts to reconnect to the FPolicy server from a Vserver. It is used to specify the number of times a broken connection will be retried. The value for this field must be between 0 and 20. By default, it is 5.

This parameter specifies the maximum number of outstanding requests for the FPolicy server. It is used to specify the maximum outstanding requests that will be queued up for the FPolicy server. The value for this field must be between 1 and 10000. By default, it is 50.

This parameter specifies the timeout for disconnecting non-responsive FPolicy servers. It is used to specify the time interval after which the connection to the FPolicy server is terminated. This happens only when the FPolicy server's queue contains the maximum allowed number of requests that it can hold in its queue and no response is received within this timeout. The maximum allowed number of requests is either 50 (the default) or the number specified by the -max-server-reqs parameter. The value for this field must be between 1s and 100s. By default, it is 60s.

This parameter specifies the interval in hours (h), minutes (m), or seconds (s) at which keep-alive messages are sent to the FPolicy server. Keep-alive messages are used to detect half-open connections. The range of supported values for this field is 10 through 600 (h, m, or s). Alternatively, the value can be set to 0, which disables keep-alive messages and prevents them from being sent to the FPolicy servers. The default value for this field is 120s.

This parameter specifies the certificate name as a fully qualified domain name (FQDN) or custom common name. The certificate is used if SSL authentication between the Vserver and the FPolicy server is configured.

This parameter specifies the serial number of the certificate used for authentication if SSL authentication between the Vserver and the FPolicy server is configured.

This parameter specifies the certificate authority (CA) name of the certificate used for authentication if SSL authentication between the Vserver and the FPolicy server is configured.

This parameter specifies the receive buffer size of the connected socket for the FPolicy server. The default value is set to 256 kilobytes (Kb). When the value is set to 0, the size of the receive buffer is set to a value defined by the system. For example, if the default receive buffer size of the socket is 65536 bytes, by setting the tunable value to 0, the socket buffer size is set to 65536 bytes. You can use any non-default value to set the size (in bytes) of the receive buffer.

This parameter specifies the send buffer size of the connected socket for the FPolicy server. The default value is set to 256 kilobytes (Kb). When the value is set to 0, the size of the send buffer is set to a value defined by the system. For example, if the default send buffer size of the socket is set to 65536 bytes, by setting the tunable value to 0, the socket buffer size is set to 65536 bytes. You can use any non-defualt value to set the size (in bytes) of the send buffer.

This parameter specifies the interval after which a new session ID is sent to the FPolicy server during reconnection attempts. The value for this field must be between 0s and 200s. The default value is set to 10 seconds. If the connection between the storage controller and the FPolicy server is terminated and reconnection is made within the -session-timeout interval, the old session ID is sent to FPolicy server so that it can send responses for old notifications.

This parameter specifies whether the resiliency feature is enabled. When this parameter is set to true and all the primary and secondary servers are down, or no response is received from the FPolicy servers, file access events are stored inside the storage controller under the specified -resiliency-directory-path . To deny the file access events from being stored under these circumstances, set this parameter to false . By default, it is false .

This parameter specifies the duration for which the notifications are written to files inside the storage controller during network outage. The value for this field must be between 0s and 600s. By default, it is set to 180s.

This parameter specifies the directory path under the -vserver namespace, where notifications are stored in the files whenever network outage happens.
