[
 {
   "memdev":"mem0",
   "pmem_size":268435456,
   "ram_size":268435456,
   "health":{
	 "maintenance_needed":true,
	 "performance_degraded":true,
	 "hw_replacement_needed":true,
	 "media_normal":false,
	 "media_not_ready":false,
	 "media_persistence_lost":false,
	 "media_data_lost":true,
	 "media_powerloss_persistence_loss":false,
	 "media_shutdown_persistence_loss":false,

	 "media_powerloss_data_loss":false,
	 "media_shutdown_data_loss":false,
	 "media_data_loss_imminent":false,
	 "ext_life_used":"normal",
	 "ext_temperature":"critical",
	 "ext_corrected_volatile":"warning",
	 "ext_corrected_persistent":"normal",
	 "life_used_percent":15,
	 "temperature":25,
	 "dirty_shutdowns":10,
	 "volatile_errors":20,
	 "pmem_errors":30
   }
