This parameter applies to imjournal: Systemd Journal Input Module.

Name:: Main
Scope:: input
Type:: boolean
Default:: input=off

Description¶

When enabled, the input module executes its bound ruleset in the main thread and pauses ingestion if the output side cannot accept data. Only the first input with Main="on" is treated as such; others run in background threads.

input(type="imjournal" Main="...")

Earlier documentation misclassified this option; it is boolean.
