Re: best automated way to construct a timeline from websense logs?

[allison nixon <elsakoo () gmail com>]

I got it to work.  I ended up using mysql and some command line shenanigans

For the benefit of everyone who might be faced with 40 gigs of log files, I
ended up doing this:

use split -l 5000 * to split every file into a reasonable sized chunk

then used ls -l to get a list of file names in the folder in a nice orderly
fashion

then created a sql database and a table called client, and set every column
type to the sort of data it would end up holding

then write a bash script that was like below. the commands were slightly
altered based on the name of every file, so the script had about 750 lines
in total.  there's probably a more elegant way to do this, with fancy
looping and variables, but no time for that.

ln -s datetime-websenselog.csvaa client.txt; mysqlimport
--fields-terminated-by=, --lines-terminated-by="\r\n" -u user
--password=password --fields-optionally-enclosed-by="\""
--columns=id,userid,hostid,wdate,wtime,wuts,srcip,srcport,dstport,dstip,resource,bytes,xfertime,code,category,allowed,hid,hostname,uid,username
client /root/Desktop/client/tobeanalyzed/Files/raw/splitted/client.txt; rm
client.txt;

the symbolic link is necessary because mysqlimport will only put the file
into the table of the same name
then i had to tweak it till the warnings went away, because mysqlimport
won't tell you the contents of those warnings, only that they have been
raised.  after some guessing games, I found out some but not all fields
were enclosed with "

Now i can run sql queries and it's somewhat trivial to find the information
i'm after now!
