could you perform the commits with the same github account and email as submitted the PR? Otherwise the CLA approval won't work

sorry, I should have built it locally before creating PR. It was complaining about the copyright and Javadoc, and I just fixed them.

@graemerocher Let me know if I need to provide any other information for the PR

Hey @umutkocasarac & @graemerocher, do you all know if this has been officially documented anywhere? I'm glad I found this issue & I appreciate your work @umutkocasarac. In an application.yml file, would you just have:

  metrics:
  ...
  http:
    ...
    server:
      ...
      percentiles:
        - 0.95
        - 0.99

I actually found this out by digging through the source:

metrics:
  binders:
    web:
      server:
        percentiles: "0.95,0.99"

I didn't find documentation on "binders", so I'm not sure where one might contribute this config to the documentation?

[umutkocasarac]

Hi @wbeard sorry for the late reply. Unfortunately, I didn't add any documentation apart from unit tests however this doc seems like a proper place to document this option.
