Health monitoring is part of the snmp configuration. I've not seen this log before but perhaps snmp is setup and not enabled for health?
set snmp health-monitor

Subject: EX3400 system alarm: Health-mon subsystem not running
Hey all,
We got some 40 used EX3400-48P and have the system alarm "Health-mon subsystem not running"
We tried recommended Junos 21.4R3-S5, as well as latest 23.4R1.9 with USB install media .
Config was zeroized and deleted completly, we don't see any config that enables/disables such subsystem. Any help to get rid of this alarm...doesn't look like any hardware failure.
