 The collector exporter can be configured explicitly in code, or via environment variables as shown above. The configuration parameters, environment variables, and defaults are shown below.

 `ssl_verify_mode:` parameter values should be flags for server certificate verification: `OpenSSL::SSL:VERIFY_PEER` and `OpenSSL::SSL:VERIFY_NONE` are acceptable. These values can also be set using the appropriately named environment variables as shown where `VERIFY_PEER` will take precedence over `VERIFY_NONE`.  Please see [the Net::HTTP docs](https://ruby-doc.org/stdlib-2.7.6/libdoc/net/http/rdoc/Net/HTTP.html#verify_mode) for more information about these flags.
