Hi all,
I'm unable to plot the data in my rrd db.
I Installed rrdtool and python-rrd for python 2.7 in a Ubuntu 14.04 os
(inside a virtualbox 32-bit machine). I created a rrd database using
python-rrd with the following syntax:
rrdtool.create('%s' % rrd_input_file, '--start', 'now', '--step', '120',
'DS:Jitter:GAUGE:5000:U:U',
'DS:PacketLossPerc:GAUGE:5000:U:U',
'RRA:AVERAGE:0.5:1:1440',
'RRA:AVERAGE:0.5:1:3600',
'RRA:AVERAGE:0.5:1:1440',
'RRA:AVERAGE:0.5:1:3600')
I update the rrd database using python-rrd with the following syntax:
for row in iperf_input:
if len(row) == 14:
epoch = str(time.mktime(time.strptime(row[0], "%Y%m%d%H%M%S")))
rrdtool.update('%s' % rrd_input_file, '%s:%s:%s' %(epoch,
row[9],row[12]))
If I execute "rrdtool dump " in a terminal window, I can see
the data. The following is an example of the output:
5.397833e-010.00e+00
4.452000e-010.00e+00
Unfortunately, I'm unable to graph the data. I'm trying to create a simple
graph without any optional parameters just to see something. The syntax is
a follows:
$ rrdtool graph -j > graph.png
Unfortunately, I don't get any output.
I would like to see a graph of my 2 metrics (Jitter and PacketLossPerc) and
the two predefined averages for each of the metrics. Can someone help?
