    @pvillard31 Thanks for the improvement! I've tested it with a standalone 
and cluster mode.
    Although uptime was displayed as expected, I felt the NiFi Cluster dialog 
became a little bit confusing because there are two 'Uptime' columns now. One 
is in 'NODES' tab, and another is 'JVM' tab.
    
    The one in 'NODES' tab is actually a timestamp denoting when the node has 
started.

    I'd suggest renaming the existing one in 'NODES' tab to something like 
`Started At`. How do you think?

> When diagnosing system performance, it would be helpful to see how long the 
> current JVM has been alive.  In one case, this could provide context helpful
