Web GUI not working after using CBench

[David Arjona]

Hi Everybody,

I have been running an ONOS cluster (3 controllers and 3 atomix servers) without problems for the past weeks using docker containers in my laptop. Last week I did some tests using CBench, which by default emulates a 16 switch network with many hosts. I tried to visualize this network using the Web GUI, but it was very large and took a long time to load, so I just closed the GUI in my browser and moved on to another task.

Then, I decided to test a smaller network again and see its behavior at the GUI. I got the Web login page as usual, but when I entered the username and password (onos/rocks) I got an error screen in return (attached file 1). I checked the logs last week and it seems that it is still trying to load the CBench network (file 2). I tried again today and I get the same behavior, although the log now shows a Java error (file 3).

I suspect the CBench network is stored in some temporary variables and it is causing conflicts when loading an empty network, but I am not sure.

Does anybody have a suggestion about how to fix this problem?

Regards,

David

To continue with this problem: I logged into the ONOS CLI and, when I used the "hosts -s" command, I could see many hosts which I assume were the ones created by CBench. Since deleting each one would take forever, I used the "wipe-out please" command. However, the computer takes a long time processing this instruction and eventually closes the ONOS CLI connection. After that, the machine hangs (it seems that the processes continue even after the CLI has died) and when I logged back in, the hosts were still recorded at the controller.

I believe I need another way to delete all the hosts, does anybody know if there is a procedure to reset the list of hosts without using the wipe-out command?

Thanks,

David
