Hi, I'm trying to get 1ms statistics for all packets with vlan priority = 2 in my capture. I use the command
tshark -n -q -r test.pcap -z "io,stat,0.001,vlan.priority==2"
But I get the following error:
tshark: invalid "-z io,stat,<interval>[,<filter>][,<filter>]...0" argument
The command with 1 second interval works fine. (tshark -n -q -r test.pcap -z "io,stat,1,vlan.priority==2")
This looks like a locale problem to me. For example, LC_NUMERIC=es_ES.UTF-8 may mean the decimal point in 0.001 is being interpreted as a comma. Here's my locale:
LANG=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_ALL=
Maybe you could try changing your locale to see if that helps?
I'm glad this worked for you, but I think it would be worth opening a bug report. You shouldn't have to be forced to change your locale for this to work. That is, if your locale uses a comma for a decimal separator, then 0,001 should work. In this case, I think it makes sense that it fails with 0.001.
There was a bug report already open, and it looks like they fixed it.
