longDescription = ''
The mcelog daemon accounts memory and some other errors in various ways
on modern x86 Linux systems. The daemon can be queried and/or execute
triggers when configurable error thresholds are exceeded. This is used to
implement a range of automatic predictive failure analysis algorithms,
including bad page offlining and automatic cache error handling. All
errors are logged to /var/log/mcelog or syslog or the journal.
