+
+#### Configuration
+
+```toml
+[[inputs.mongodb]]
+  ## An array of URI to gather stats about. Specify an ip or hostname
+  ## with optional port add password. ie,
+  ##   mongodb://user:auth_key@10.10.3.30:27017,
+  ##   mongodb://10.10.3.33:18832,
+  ##   10.0.0.1:10000, etc.
+  servers = ["127.0.0.1:27017"]
+```
+
+For authenticated mongodb istances use connection mongdb connection URI
+
+```toml
