[ovs-discuss] Capturing timestamp in a switch

2016-10-17 Thread Ajeeth Kannan (RIT Student)
Hi Team, I would like to get the timestamp for the packets that are being captured by an OVS. Is there any possible command to do it or should I need to modify the OVS code to do this ? Should I query the DB or flow-tables to get the timestamps of the captured packets ? Thank you, Ajeeth Kannan

[ovs-discuss] Regarding storing data in OVS

2016-10-31 Thread Ajeeth Kannan (RIT Student)
Hello, I have altered the code in datapath module of OVS to access the timestamp of a packet. I want to know how to store the timestamp information and see it. Could I use the OVSDB to store the information or do I need to have a netlink socket to store it in userspace ? Thank you, Ajeeth Kannan

[ovs-discuss] Tweaking FlowStats

2016-12-09 Thread Ajeeth Kannan (RIT Student)
Hello, I have been trying to learn how flowstats is being implemented in openvswitch. So, I have tweaked flowstats by adding a field named *check_field *in the datapath module. check_field would be incremented same as the packet_count. Accordingly, I have tracked the netlink connection between

Hello, I find it difficult to debug OVS files without any debuggers. Would you suggest me to use GDB or is there any specific techniques to debug the problem ? As both user space and kernel space modules in OVS run as daemon process will I be able to debug it using GDB ? Thank you, Ajeeth Kannan
