Forward source plugin

Fluent Bit Forward uses a lightweight protocol, called Forward, that is optimized for low-latency and high-throughput data transmission over the network. It supports both TCP and UDP transport protocols and provides options for configuring data buffering and batching to optimize network usage.

You can use the Forward source plugin to configure your Calyptia Core pipeline to collect data from your Forward services.

Configuration parameters

The Forward source plugin provides these configuration parameters.


HostListener network interface.
PortTCP port used for listening for incoming messages.
Unix Socket PathSpecify the path to Unix socket to receive a Forward message. If set, Listen and Port are ignored.
Unix SocketSet the permission of the Unix socket file. If Unix_Path is not set, this parameter is ignored.
Max Buffer SizeSpecify the maximum buffer memory size used to receive a Forward message. The value must be according to the Unit Size specification.
Buffer Chunk SizeBy default the buffer to store the incoming Forward messages, do not allocate the maximum memory allowed, instead it allocate memory when is required. The rounds of allocations are set by Buffer_Chunk_Size. The value must be according to the Unit Size specification.
Tag PrefixPrefix incoming tag with the defined value.
