This approach is fine for relatively well-behaved distributions. Anything
more skewed than, say, an exponential or as long tailed as a t(3)
distribution is likely to have troubles with this approach.

Phil,
A big part of the problem as I understand it is that these rates are needed
across a potentially quite large distributed system.

As far as I know you can't list files using the http or https filesystem
implementation, just copy single files for which you know the URL.
It would be a nice extension I agree...

Hi,
I want to copy files through https. The source URL has listing of directories
enabled.
I made some test code to copy files. Ultimately, I want to do this:
FileSystemManager fsManager = VFS.getManager();
FileObject fileObject = fsManager.resolveFile(
"https://localho
For the overall average you need is the total time and total characters. Do
the division at presentation time.
If you want a decaying moving average, then a variant on Welford's method is
useful for an on-line estimate. I just had such a discussion in the hbase
group. For that you need state, h
Please excuse the following ignorant question.
I want to maintain summary statistics of a rate. At each 'event', I
know the number of characters and the time it took to process them,
and I want to maintain summary statistics for the rate of
chars/second. I imagine that I'm missing something basic,
Hello,
I am using the VFS to monitoring one folder, when I receipt one file , but
when I receive one file in a sub-folder the process don´t should execute.
How can I use VFS to monitoring only in the root directory?
Atenciosamente,
