How to configure the Grafana Flow agent on a Windows host with remote path storage

config.river

logging {
  level = "info"
}

discovery.http "path_targets" {
  url = "target_url_to_get_log_paths"
}

discovery.relabel "paths" {
  targets = discovery.http.path_targets.targets
  
  // Relabel for local.file_match component
  rule {
    source_labels = ["__address__"]
    target_label  = "__path__"
    action        = "replace"
  }
  
  // Drop unneeded labels
  rule {
    regex         = "__meta_url"
    action        = "labeldrop"
  }

  rule {
    regex         = "__address__"
    action        = "labeldrop"
  }
}

local.file_match "logs" {
  path_targets = discovery.relabel.paths.output
}

loki.source.file "files" {
  targets    = local.file_match.logs.targets
  forward_to = [loki.write.loki.receiver]
}

loki.write "loki" {
  endpoint {
    url = "http://loki_server:3100/loki/api/v1/push"
  }
}

/* JSON response which should be returned to discovery.http component
[
  {
    "targets": [
      "C:/folder_1/logs/*.log",
      "C:/folder_2/logs/app_1/main/*.log",
      "D:/folder_3/*.log"
    ]
  }
]
*/

Took me a while to figure out this one.
