Overview

Validates memory configuration by verifying the number of DIMMs and total memory size against expected values using dmidecode.

Command-Line Options

Option	Type	Default	Description
--dimms	Integer	Auto-detected	Expected number of memory DIMMs
--total-size	Integer	Auto-detected	Expected total memory in GB
--timeout	Integer	300	Command execution timeout in seconds
--sink	String	do_nothing	Telemetry sink destination
--sink-opts	Multiple	-	Sink-specific configuration
--verbose-out	Flag	False	Display detailed output
--log-level	Choice	INFO	DEBUG, INFO, WARNING, ERROR, CRITICAL
--log-folder	String	/var/log/fb-monitoring	Log directory
--heterogeneous-cluster-v1	Flag	False	Enable heterogeneous cluster support

Exit Conditions

Exit Code	Condition
OK (0)	Feature flag disabled (killswitch active)
OK (0)	DIMMs and memory size match
WARN (1)	dmidecode command failed
CRITICAL (2)	Configuration mismatch
