Richard,
thanks for the pointer to the right file. Here is what I ended up doing
to get some statistics:
1.) sort -k 3,3 > peerstats.20060519.sorted,
which just by IP address
2.) cat peerstats.20060520.sorted | grep -e "127.127.30.0" >
which just greps the lines containing "127.127.30.0" (the oncore drivers
IP)
3.) Import peerstats.20060520.sorted.grepped in Excel, but I guess I could
have imported peerstats.20060519 directly and then filtered in Excel. Save
the file
4.) Use matlab to load the file and plot the desired parameters.
So after all not a big deal, once one knows that peerstats is already
containing the desired information. -- Mario
