There are a number of reasons for this change: - Modules allow a single instance of the exporter to be configured with numerous different tls configs. Previously you had to run a different exporter for each combination. - Adding new and more complicated options to the exporter should be easier with modules than if I was to go down the route of accepting configuration directly through url params - I prefer defining a specific prober (https,tcp) over using the URL to guess what the user wants

// However, official binary prefixes are always capitalized - "KiB" -

|
|
// (1) people pedantic enough to use lowercase according to SI unlikely to abuse "k" to mean 1024 :-)
|
|
//
|
|
// (2) Use of capital K for 1024 was an informal tradition predating IEC prefixes:
|
|
// "The binary meaning of the kilobyte for 1024 bytes typically uses the symbol KB, with an
|
|
// uppercase letter K."
|
|
// -- https://en.wikipedia.org/wiki/Kilobyte#Base_2_(1024_bytes)
|
|
// "Capitalization of the letter K became the de facto standard for binary notation, although this
|
|
// could not be extended to higher powers, and use of the lowercase k did persist.[13][14][15]"
|
|
// -- https://en.wikipedia.org/wiki/Binary_prefix#History
