Hi, I can get indication of Xen_ComputerSystemCreatedIndication successfully after define a new domain, which done by "python indication_tester.py Xen_ComputerSystemCreateddIndication" on sfcb. On Pegasus, we have to pass three arguments at least, right? Below is the execution command: "python indication_tester.py -u localhost:5988 -U root -P password Xen_ComputerSystemDeletedIndication". However, it's still in watching status, and I can't get any info for several minutes. Who knows why it is? Is there some mistake in my operation on Pegasus? Thanks!
