compression.driver¶

Selects the decompression driver for imtcp stream-compressed TCP input.

This parameter applies to imtcp: TCP Syslog Input Module.

Name:: compression.driver
Scope:: input/module
Type:: word
Default:: input=zlib
Required?:: no
Introduced:: 8.2606.0

Description¶

compression.driver selects the decompression library used when compression.mode="stream:always" is configured.

Accepted values are:

zlib: default stream decompression driver.
zstd: zstd stream decompression driver. This requires rsyslog to be built with libzstd support, and the omfwd sender must also use compression.driver="zstd".

The driver setting must match the sender. A zstd-compressed stream cannot be received with compression.driver="zlib", and a zlib-compressed stream cannot be received with compression.driver="zstd".

Input usage¶

input(
    type="imtcp"
    port="514"
    compression.mode="stream:always"
    compression.driver="zstd"
)
