# in memory exceeds a pre-configured corrected error threshold.
# mcelog internally also supports offlining the page through the kernel.

# MESSAGE Human readable consolidated error message
# TOTALCOUNT total count of errors for current DIMM of CE/UC depending on
# what triggered the event
# LOCATION Consolidated location as a single string
# DMI_LOCATION DIMM location from DMI/SMBIOS if available
# DMI_NAME DIMM identifier from DMI/SMBIOS if available
# DIMM DIMM number reported by hardware
# CHANNEL Channel number reported by hardware
# SOCKETID Socket ID of CPU that includes the memory controller with the DIMM
# CECOUNT Total corrected error count for DIMM
# UCCOUNT Total uncorrected error count for DIMM
# LASTEVENT Time stamp of event that triggered threshold (in time_t format, seconds)
# THRESHOLD_COUNT Total umber of events in current threshold time period of specific type
