[Ovmsdev] Data logging

I'm working on a project to log and analyze data from different
electric vehicles, and I'm testing the OVMS on a Renault Twizy.
Basically, my goal is to log all important data relative to the
battery health, like single cell voltages and temperatures, every time
these details are sent through the CAN bus. The last update from Mark
about Drive and Charge logging looked interesting to me, so I have
recompiled and uploaded the last version from github and now I have a
- By setting bits of feature #13, do you mean sending a command like
"S FEATURE 13 3" to set them both?
- How much data will be recorded? Will it record cell voltages every
second, for example?
I'm also having a few problems with the server, I'm running it from my
pc, but I keep getting this error:
2013-08-20 03:11:09.570207 -0700 info main: #8 - new ovms connection
2013-08-20 03:11:11.176338 -0700 info main: #8 - - rx MP-C 0

2013-08-20 03:11:11.177198 -0700 error main: #8 TEST123 error -
Incorrect client authentication - aborting connection
I tried to change passwords and encryption scheme from the DB, but I
still get that error.
I'd also like to know if you think that the OVMS is a good option for
my needs, because it looks like the goal of the OVMS is too different
from mine, so I may need to rewrite the PIC firmware to just dump the
data from the CAN bus and push it through to my server, then parse it
