Hi,
After running flow-capture beginning december 1, I looked into the flows
directory and it has tremendously grown into 16Gig in size.
As of now it contains 6005 pieces of 5-minute flows. My goal is to run
"flow-cat all_December_flows | flow-stat -f 8", however I'm having a
difficulty when executing this command.
Flow-cat's output is generally larger than its input because of the
change in format.
Rather than keep all your flow files in the same directory, you may want
to set up a date-based directory structure. For example, you could
store your files for December 21 in the directory
/var/netflow/ft/all/2006/2006-12/2006-12-21/. Since you can use a
directory (all files under the directory will be read) or a file as
input, that would avoid the shell expansion limit you've been hitting.
You may run into a memory limit depending on your volume of data, or it
may work just fine.
