+## Volumes
+None
+
+## Run
+```shell
+docker run --name telegraf \
+    -v /.../telegraf.conf:/telegraf/etc/telegraf.conf:ro \
+    -d 11notes/telegraf:[tag]
+```
+
+# Examples telegraf.conf
+```shell
+[agent]
+  interval = "10s"
+  round_interval = true
+  metric_batch_size = 1000
+  metric_buffer_limit = 10000
+  collection_jitter = "0s"
+  flush_interval = "10s"
+  flush_jitter = "0s"
+  precision = "0s"
+  hostname = "telegraf"
