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:
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.
How do you expect to deduce a failure rate from a single point in time? Are you instead maybe looking for a percentage of network node failures at this point in time?
What output are you hoping to produce from the sample input you have provided?
What have you tried on your own to get the output you want?

This is only a simple example. I will generate an history of some days.
What output are you hoping to produce from the sample input you have provided?
The MTBF (mean-time-between-failures) of each node.
What have you tried on your own to get the output you want?
You said you want the MTBF for each node. The node 127.0.0.1 was always down (for all three times it appeared in the data in post #4 and for both times it appeared in the data in post #1).
If a node is never up, isn't the mean time between failures zero? What value were you expecting?

There was a problem with our data center today, creating a site outage (server unreachable).
That problem has been resolved.
Basically, it seems to have been a socially engineered denial-of-service attack against UNIX.com; which I stopped as soon as I found out what the problem was.

Dear All,
There was a problem in the data center data, which caused the server to be unreachable for about an hour.
Server logs show the server did not crash or go down.
Hence, I assume there was a networking issue at the data center.
Still waiting for final word on what happened.

Three days ago we received an expected notice from our long time data center that they were going dark on Sept 12th.
About one and a half hours ago, after three days of marathon work, I just cut over the unix.com to a new data center with a completely new OS and Ubuntu distribution. (22 Replies)
