///Help here to sort out stage.match instead of stage.drop

local.file_match "local_files" {
  path_targets = [{
    __address__ = "localhost",
    __path__    = "/var/log/28/log.log",
  }]
}

loki.source.file "log_scrape" {
  targets = local.file_match.local_files.targets
  forward_to = [loki.process.filter_logs.receiver]
}

//drop all but selector "!~"
loki.process "filter_logs" {
  stage.match {
    selector = "{filename=\"/var/log/28/log.log\"} !~ \".*the_only_text_to_send_to_Loki\""
    action = "drop"
  }
  forward_to = [loki.write.grafanacloud.receiver]
}

loki.write "grafanacloud" {
  endpoint {
    url = "https://logs-prod-us-central1.grafana.net/loki/api/v1/push"

    basic_auth {
      username = "grafanacloudusername"
      password = "grafana_auth_token"
    }
  }
