Variables¶

# Configuration values:
step = 60
directory = /var/local/rrd
loglevel = LOG_NOTICE

Patterns¶

# System statistics:
file:///proc/stat
"cpu %d %d %d %d"    stat.rrd:user,nice,system,idle
"processes %u"       stat.rrd:processes
"swap %u %u"         stat.rrd:swap_in,swap_out

# System load: 1, 5 and 15 min. average
file:///proc/loadavg
"%f %f %f"           avg1.rrd:load,avg5.rrd:load,avg15.rrd:load

# Memory usage:
file:///proc/meminfo
"Mem:  %*d %d %d %d %d %d"    memory.rrd:used,free,shared,buffers,cached
"Swap: %*d %d %*d"            memory.rrd:swap_used

# S.M.A.R.T. HDD temperature:
file:///proc/ide/hda/smart_values
7:"%*04x %*04x %02x%*02x"       temperature.rrd:hda

Regular expressions¶

# Using regular expressions:
file:///proc/stat
/cpu  (\d+) (\d+) (\d+) (\d+)/    stat.rrd:user,nice,system,idle
