# This config file is used to generate Monasca metrics from logs ingested
# by the Monasca Log API. Alarms and notifications can then be set to alert
# users when a particular log message is ingested. This example config file
# generates metrics for all logs which have a log level which isn't
# debug, trace or info level. A user may want to apply additional logic to
# generate special metrics when particular log messages are ingested. For
# example, if HAProxy fails over, file system corruption is detected or
# other scenarios of interest.
