Hi @treydock

I was wondering if this exporter has support for TLS encryption via something like web.yml where you can specify the server side config similar to node exporter something like

tls_server_config:
  client_ca_file: "/etc/node_exporter/certs/serer-ca.crt"
  cert_file: "/etc/node_exporter/certs/server.crt"
  key_file: "/etc/node_exporter/certs/server.key"
  client_auth_type: "RequireAndVerifyClientCert"
