I am currently running DUMPCAP as a service to capture packets in a high packet throughput environment. The command used is: /usr/local/bin/dumpcap -B 16 -i 2 -f vlan and (not vrrp and not udp port 1985 and not ether host 01:00:0c:cc:cc:cc) -g -b filesize:250000 -b duration:900 -w /data/eth1.cap I am experiencing disk IO issues. I suspect that part of my disk IO issue is due to copying the rotated file from \tmp to \data
Have you seen it copying the file from /tmp to /data? Or are you just *assuming* it's writing the files to /tmp and copying them rather than just writing directory to files in /data? It would be unwise to assume that, given that, in fact, it *doesn't* do that (and *didn't* do that in a test I just did); if you're seeing it copy the file, that's a bug. ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
