question about ra -s flag

[Nick Giordano]

I seem to be getting inconsistent results depending on what I give to 
the -s flag of ra (Ra Version 2.0.6.fixes.1).  Some of the results have 
a ',' prepended and others do not.

My rarc file is:
RA_FIELD_DELIMITER=','
RA_PRINT_UNIX_TIME=yes

ra -s rate -r out/jan_19_out gives
...
,18.08,14.47
,20.05,16.04
,0.00,0.00
,39.05,22.80
...

while

ra -s spkts -r out/jan_19_out gives
...
14
1
1
2
1
30
...

And speaking of the 'rate' field, what do the two values mean?

Additionally, what is the second field of an ra query with no options?

 /data/beancounter $ ra -r out/jan_19_out
1106110724,,udp,xxx.xxx.xxx.xxx,1948,->,xxx.xxx.xxx.xxx,1948,1,0,478,0,INT
1106110680,I,udp,xxx.xxx.xxx.xxx,->,xxx.xxx.xxx.xxx,netbi,6,0,1842,0,INT

Also, the -A flag will give byte counts of application data instead of 
total byte size, is there any possibility of this being added as a field 
option so we could have total bytes and application bytes on the same 
output line?

Thanks,

Nick
