# 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.

# You will need to emit messages similar to the following in order to add a

# a metric using this process.  You will need to emit both a start and stop

# time and the metric reported will be the difference in values

# Nov 15 08:05 localhost PROGRAM_NAME[822]: start METRIC_NAME time 12 sectors 56

# Nov 15 08:05 localhost PROGRAM_NAME[822]: stop METRIC_NAME time 24 sectors 68

# If you add metrics without a start, it is assumed you are requesting the

# time differece from system start

# Metrics we are interested in measuring
