So this is what I have as of right now
import rrdtool
import os
import time
import string
interval = 10
interval = str(interval)
interval_mins = float(interval) / 60
heartbeat = str(int(interval) * 2)
rrdtool.create('usr.rrd',
'DS:usr_info:COUNTER:%s:U:U' % heartbeat,
'RRA:AVERAGE:0.5:1:%s' % int(4000 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(30 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(120 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(1440 / interval_mins))
rrdtool.create('sys.rrd',
'DS:sys_info:COUNTER:%s:U:U' % heartbeat,
'RRA:AVERAGE:0.5:1:%s' % int(4000 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(30 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(120 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(1440 / interval_mins))
rrdtool.create('idle.rrd',
'DS:idle_info:COUNTER:%s:U:U' % heartbeat,
'RRA:AVERAGE:0.5:1:%s' % int(4000 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(30 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(120 / interval_mins),
'RRA:AVERAGE:0.5:%d:800' % int(1440 / interval_mins))
while True:
infile= open('/proc/stat', 'r')
#for x in range(0,1): #Reads first line only
line = infile.readline()
if line.startswith('cpu'): #Check to make sure in 1st line
info = line.split() #Returns a list of the words in the string
usr_info = info[1] #Index the three aspects of CPU Usuage
rrdtool.update('usr.rrd','N:12322')
sys_info = info[3]
rrdtool.update('sys.rrd','N:12322')
idle_info = info[4]
rrdtool.update('idle.rrd','N:100000000') #str() because Python
needs to have a string
print usr_info, sys_info, idle_info #Print out so you can see
what's happening
time.sleep(10)
#cur_date=time.strftime('%m/%d/%Y %H\:%M\:%S', time.localtime())
rrdtool.graph('example.png',
'--start','now-%s'%(60*60),
'--end','now',
'--width','400',
'--height','150',
'--base', '1000',
'--vertical-label','CPU Usuage',
'--title', 'EXAMPLE',
'DEF:ds0=usr.rrd:ds0:AVERAGE ', #Defines all three aspects of
the /proc/stat file
'DEF:ds1=sys.rrd:ds1:AVERAGE:step=800',
'DEF:ds2=idle.rrd:ds2:AVERAGE:step=800',
'AREA:ds0#0000FF:"User CPU usuage"', #Different Labels for
each of the three ascp
'AREA:ds1#00FF00:"System CPU usuage"',
'AREA:ds2#FF0000:"Idle CPU usuage"')
(it is all aligned properly) but I get this error message
python mult_rrd.py
256918 107489 111479877
Traceback (most recent call last):
File "mult_rrd.py", line 58, in ?
'AREA:ds2#FF0000:"Idle CPU usuage"')
rrdtool.error: Cannot parse CF in 'DEF:ds0=usr.rrd:ds0:AVERAGE '
