+# Grafana Loki Output Plugin
+
+This plugin writes logs to a [Grafana Loki][loki] instance, using the metric
+name and tags as labels. The log line will contain all fields in
+`key="value"` format easily parsable with the `logfmt` parser in Loki.
+
+Logs within each stream are sorted by timestamp before being sent to Loki.

+## Configuration
+
+```toml @sample.conf
+# A plugin that can transmit logs to Loki
+[[outputs.loki]]
+  ## The domain of Loki
+  domain = "https://loki.domain.tld"
+
+  ## Endpoint to write api
+  # endpoint = "/loki/api/v1/push"
+
+  ## Connection timeout, defaults to "5s" if not set.
+  # timeout = "5s"
+
+  ## Basic auth credential
+  # username = "loki"
+  # password = "pass"
+
+  ## Additional HTTP headers
+  # http_headers = {"X-Scope-OrgID" = "1"}
+
+  ## If the request must be gzip encoded
+  # gzip_request = false
+
+  ## Optional TLS Config
+  # tls_ca = "/etc/telegraf/ca.pem"
+  # tls_cert = "/etc/telegraf/cert.pem"
+  # tls_key = "/etc/telegraf/key.pem"
+
+  ## Sanitize Tag Names
+  ## If true, all tag names will have invalid characters replaced with
+  ## underscores that do not match the regex: ^[a-zA-Z_:][a-zA-Z0-9_:]*.
+  # sanitize_label_names = false
+
+  ## Metric Name Label
+  ## Label to use for the metric name to when sending metrics. If set to an
+  ## empty string, this will not add the label. This is NOT suggested as there
+  ## is no way to differentiate between multiple metrics.
+  # metric_name_label = "__name"
+```
