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.

Specify the path to Unix socket to receive a Forward message. If set, Listen and Port are ignored.
Unix Socket
Set the permission of the Unix socket file. If Unix_Path is not set, this parameter is ignored.
Max Buffer Size
Specify the maximum buffer memory size used to receive a Forward message. The value must be according to the Unit Size specification.
Buffer Chunk Size
By 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 Prefix
