Compression.mode

Selects decompression mode matching compression used by omfwd.

This parameter applies to imptcp: Plain TCP Syslog.

Name:

Compression.mode

Scope:

input

Type:

word

Default:

input=none

Required?:

no

Introduced:

at least 5.x, possibly earlier

Description

This is the counterpart to the compression modes set in omfwd. imptcp accepts the following values:

  • none - do not attempt stream decompression.

  • stream:always - treat the full TCP byte stream as a zlib-compressed stream generated by omfwd with compression.mode="stream:always".

This receive path is a fixed-policy implementation:

  • it uses streaming zlib decompression during normal receives,

  • it performs a final decompression drain when the TCP session closes,

  • it is compatible with sender-side compression.stream.flushOnTXEnd="on" and "off",

  • it logs malformed or truncated compressed streams and closes the session.

imptcp does not support the sender-side single compression mode here.

Input usage

input(type="imptcp" compression.mode="stream:always")
