## Example config file for mcelog# mcelog is the user space backend that decodes and process machine check events# (cpu hardware errors) reported by the CPU to the kernel## general format#optionname = value# white space is not allowed in value currently, except at the end where it is dropped## in general all command line options that are not commands work here# see man mcelog or mcelog --help for a list# e.g. to enable the --no-syslog option use#no-syslog = yes (or no to disable)# when the option has a argument#logfile = /tmp/logfile# by default, disable extended error logging on newer Intel processorsno-imc-log = yes# below are the options which are not command line options# Set CPU type for which mcelog decodes events:#cpu = type# for valid values for type please see mcelog --help# If this value is set incorrectly the decoded output will be likely incorrect.# by default when this parameter is not set mcelog uses the CPU it is running on# on very new kernels the mcelog events reported by the kernel also carry# the CPU type which is used too when available and not overriden.# Enable daemon mode:#daemon = yes# By default mcelog just processes the currently pending events and exits.# in daemon mode it will keep running as a daemon in the background and poll# the kernel for events and then decode them.# Filter out known broken events by defaultfilter = yes# don't log memory errors individually# they still get accounted if that is enabled#filter-memory-errors = yes# output in undecoded raw format to be easier machine readable# (default is decoded)#raw = yes# Set CPU Mhz to decode uptime from time stamp counter (output# unreliable, not needed on new kernels which report the event time# directly. A lot of systems don't have a linear time stamp clock# and the output is wrong then.# Normally mcelog tries to figure out if it the TSC is reliable# and only uses the current frequency then.# Setting a frequency forces timestamp decoding.# This setting is obsolete with modern kernels which report the time# directly.#cpumhz = 1800.00# log output options# Log decoded machine checks in syslog (default stdout or syslog for daemon)#syslog = yes# Log decoded machine checks in syslog with error level#syslog-error = yes# Never log anything to syslog#no-syslog = yes# Append log output to logfile instead of stdout.
