Re: [Flent-users] [tohojo/flent] Couldn't resolve host name' while getting URL list at http://%s/filelist.txt (#137)
I would like to send a fixed amount of data (I am more used to iperf) so for
instance run 10 times ` iperf -c HOST -n 6MB` and show a cdf of the completion
times.
I kinda understand the .conf format and came up with my own script:
```
DESCRIPTION="iperf completion delay 6MB"
DEFAULTS={'PLOT': "iperf_delay",
'HOSTS': []}
IPERF_V6=""
if IP_VERSION == 6:
IPERF_V6="-V"
DATA_SETS = o([
('TCP iperf',
# -n => fixed number of byte
{'command': "iperf -c %s -i %.2f -y C -n 6M %s" % (HOST,
max(0.5,STEP_SIZE), IPERF_V6),
'delay': DELAY, # do I need this anymore ?
'units': 'second',
'runner': 'iperf_csv',})
])
PLOTS['iperf_delay'] = {'description': 'Iperf completion time',
'type': 'timeseries',
'series': [
{'data': 'TCP iperf',
'label': 'completion delay (ms)'}]}
],
```
My problem is on how to retrieve the actual data, i.e. the delay taken by the
iperf connection. I see that the runners have a parse function and a
self._raw_values
Just for info here is the output.
```
iperf -n 6M -c localhost --enhancedreports

Could you explain in a bit more detail what it is you're trying to do? The HTTP tests already included already have a CDF plot (it's just called delay instead of completion time; so the plot is http_delay_cdf). -- You are receiving this because you are subscribed to this thread.

Yup, you are quite right...
