This parameter applies to imptcp: Plain TCP Syslog.

Name:

Threads

Scope:

module

Type:

integer

Default:

module=2

Required?:

no

Introduced:

at least 5.x, possibly earlier

Description

Number of helper worker threads to process incoming messages. These threads are utilized to pull data off the network. On a busy system, additional helper threads (but not more than there are CPUs/Cores) can help improving performance. The default value is two, which means there is a default thread count of three (the main input thread plus two helpers). No more than 16 threads can be set (if tried to, rsyslog always resorts to 16).

Module usage

module(load="imptcp" threads="...")

Legacy names (for reference)
