This was originally reported as a bug on the wavefront telegraf plugin: influxdata/telegraf#11925

senders.CreateConfig("http://localhost:8071/wavefront") currently removes the port portion of the url during the parsing process. This doesn't create any problems for urls without a path component, but when port and path are both present, the resulting url is mangled: "http://localhost/wavefront", and the port is then appended by the reporter later, resulting in something like "http://localhost/wavefront:8071/report?f=wavefront".

I'm hoping to submit a PR with test cases in the next couple of hours.
