 ### Configuration:
 
 ```toml
 # Read raindrops stats
 [[inputs.raindrops]]
-  urls = ["http://localhost/_raindrops"]
+  urls = ["http://localhost:8080/_raindrops"]
 ```
 
+### Measurements & Fields:
+
+- raindrops
+    - calling (integer, count)
+    - writing (integer, count)
+- raindrops_listen
+    - active (integer, bytes)
+    - queued (integer, bytes)
+
 ### Tags:
 
-- Multiple listeners are tagged with IP:Port/Socket, ie `0.0.0.0:8080` or  `/tmp/unicorn`
+- Raindops calling/writing of all the workers:
+    - server
+    - port
+
+- raindrops_listen (ip:port):
+    - ip
+    - port
+
+- raindrops_listen (Unix Socket):
+    - socket
+
+### Example Output:
+
+```
