Diode type

Used to transmit events using a data diode.

When creating this type of connector, you need to define values for the following settings:

• Basic settings tab:
  • Name (required)—a unique name for this type of resource. Must contain 1 to 128 Unicode characters.
  • Tenant (required)—name of the tenant that owns the resource.
  • Type (required)—connector type, diode.
  • Data diode destination directory (required)—full path to the KUMA collector server directory where the data diode moves files containing events from the isolated network segment. After the connector has read these files, the files are deleted from the directory. The path can contain up to 255 Unicode characters.

    Limitations when using prefixes in paths

    Prefixes that cannot be used when specifying paths to files:

    • /*
    • /bin
    • /boot
    • /dev
    • /etc
    • /home
    • /lib
    • /lib64
    • /proc
    • /root
    • /run
    • /sys
    • /tmp
    • /usr/*
    • /usr/bin/
    • /usr/local/*
    • /usr/local/sbin/
    • /usr/local/bin/
    • /usr/sbin/
    • /usr/lib/
    • /usr/lib64/
    • /var/*
    • /var/lib/
    • /var/run/
    • /opt/kaspersky/kuma/

    Files are available at the following paths:

    • /opt/kaspersky/kuma/clickhouse/logs/
    • /opt/kaspersky/kuma/mongodb/log/
    • /opt/kaspersky/kuma/victoria-metrics/log/
  • Delimiter is used to specify a character representing the delimiter between events. Available values: \n, \t, \0. If no separator is specified (an empty value is selected), the default value is \n.

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

  • Description—resource description: up to 4,000 Unicode characters.
• Advanced settings tab:
  • Workers—the number of services processing the request queue. By default, this value is equal to the number of vCPUs of the KUMA Core server.
  • Poll interval, sec —frequency at which the files are read from the directory containing events from the data diode. The default value is 2. The value is specified in seconds.
  • Character encoding setting specifies character encoding. The default value is UTF-8.
  • 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.

  • Debug—a toggle switch that lets you specify whether resource logging must be enabled. By default, this toggle switch is in the Disabled position.
