Hi,

>From the collector log RESP BODY messages I understand that in the
beginning there were the following servers:
compute1: deltesting
ubuntu: Apigateway, KubeMaster and others

After ~20minutes, there was only Apigateway. Does it make sense? did you
delete the instances on ubuntu, in addition to deltesting?
In any case, I would expect to see the instances deleted from the graph at
this stage, since they were not returned by get_all.
Can you please send me the log of vitrage-graph at the same time (Nov 15,
16:35-17:10)?

There is still the question of why we don't see a notification from Nova,
but let's try to solve the issues one by one.

Thanks,
Ifat
