ProcessOnPoller

Processes messages on the poller thread when feasible to reduce resource use.

This parameter applies to imptcp: Plain TCP Syslog.

Name:

ProcessOnPoller

Scope:

module

Type:

boolean

Default:

module=on

Required?:

no

Introduced:

at least 5.x, possibly earlier

Description

Instructs imptcp to process messages on poller thread opportunistically. This leads to lower resource footprint (as poller thread doubles up as message-processing thread too). “On” works best when imptcp is handling low ingestion rates.

At high throughput though, it causes polling delay (as poller spends time processing messages, which keeps connections in read-ready state longer than they need to be, filling socket-buffer, hence eventually applying backpressure).

It defaults to allowing messages to be processed on poller (for backward compatibility).

Module usage

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