Hi Alfredo/Ntop team, I have been successfully able to pump the data at ~4-5Gbps using below command - /usr/local/bin/disk2n -m */home/list_of_pcap.txt* -i zc:eth4 *-I 1050* -O -g -C 64 -b 2048 -c 1 -w 2 -S 3 -v
I have 1 TB of data present in multiple pcap files , size ranging from 3-12 GB and name of pcaps are given in */home/list_of_pcap.txt. *After executing 2 files of 4-5GB, it starts giving the below errors continuously and pumping traffic intermittently. 09/Mar/2016 00:53:27 [disk2n.c:1594] WARNING: [sender] waiting.. (buffer empty) 09/Mar/2016 00:53:27 [disk2n.c:1594] WARNING: [sender] waiting.. (buffer empty) 09/Mar/2016 00:53:27 [disk2n.c:1594] WARNING: [sender] waiting.. (buffer empty) Can you please help what am I missing here and please let me know if we need to check something on server. I have 12 GB RAM on rhel server.
