 # This script parses /var/log/syslog for messages from programs that log
 # uptime and disk stats (number of sectors read).  It then outputs
 # these stats in a format usable by the metrics collector, which forwards
 # them to autotest and UMA.
 
 # To add a new metric add a line below, as PROGRAM_NAME  METRIC_NAME.
 # PROGRAM_NAME is the name of the job whose start time we
 # are interested in.  METRIC_NAME is the prefix we want to use for
 # reporting to UMA and autotest.  The script prepends "Time" and
 # "Sectors" to METRIC_NAME for the two available measurements, uptime
 # and number of sectors read thus far.
