Description

JvmPauseMonitor prints multiline message in the log.

om_1     | 2021-01-29 14:59:37,955 [org.apache.ratis.util.JvmPauseMonitor$$Lambda$364/0x0000000840497c40@47272cd3] WARN util.JvmPauseMonitor: JvmPauseMonitor-om1: Detected pause in JVM or host machine (eg GC): pause of approximately 188209400ns
om_1     |
om_1     | No GCs detected

I think the empty line should be avoided, and the "No GCs detected" could fit in the same single line. Printing each GC pool in its own line, in case of collection, is fine.
