Please, i have a history of the state of each node in my data center. an history about the failure of my cluster (UN: node up, DN: node down).
Here is some lines of the history:
08:51:36 UN 127.0.0.1 08:51:36 UN 127.0.0.2 08:51:36 UN 127.0.0.3 08:53:50 DN 127.0.0.1 08:53:50 DN 127.0.0.2 08:53:50 DN 127.0.0.3
I'd like from this history, deduce the failure rate of each node. How can i do that please ? i have for example, to use AI technologies ML or i have to sum UN of each node and divide it on the number of line.
Thank you so much for help. Kind regards.
