Temporary directory

Directory in which events are prepared for transmission to the data diode.

Events are stored in a file when a timeout (10 seconds by default) or a buffer overflow occurs. The prepared file is moved to the directory specified in the Data diode source directory field. The checksum (SHA-256) of the file contents is used as the name of the file containing events.

The temporary directory must be different from the data diode source directory.

Description

Compression

You can use Snappy compression. By default, compression is disabled.

This setting must match for the connector and destination resources used to relay events from an isolated network segment via the data diode.

Buffer size

Sets the size of the buffer.

The default value is 1 KB, and the maximum value is 64 MB.

Delimiter

In the drop-down list, you can select the character to mark the boundary between events. By default, \n is used.

This setting must match for the connector and destination resources used to relay events from an isolated network segment via the data diode.

Buffer flush interval

Time (in seconds) between sending batches of data to the destination. The default value is 1 second.

Number of handlers

This field is used to set the number of services processing the queue. By default, this value is equal to the number of vCPUs of the KUMA Core server.

Debug

This toggle switch lets you specify whether resource logging must be enabled. The default value is Disabled.
