Support password authentication in the Solr plugin

Feature Request

Support password authentication in the Solr plugin, using Basic HTTP Authentication.

Proposal:

The Solr plugin should work with Solr instances with enabled authentication.

Current behavior:

401 status code when the plugin tries to request Solr node with enabled authentication.

Desired behavior:

200 status code

Use case:

Solr nodes, especially in prod environment, often use the authentication.

Agreed, we should include the regular HTTP options along with this:

  ## Optional HTTP Basic Auth Credentials
  # username = "username"
  # password = "pa$$word"

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## Amount of time allowed to complete the HTTP request
  # timeout = "5s"

I've changed solr.go in order to have authenticated access and tested it with my Solr instances. May I push a request to some branch?

[danielnelson]

Yes, create a fork of this repo and then push it to a branch on the fork, then you can create the pull request from there.
