+# Swap Input Plugin
+
+The swap plugin collects system swap metrics.
+
+For a more information on what swap memory is, read [All about Linux swap space](https://www.linux.com/news/all-about-linux-swap-space).
+
+### Configuration:
+
+```toml
+# Read metrics about swap memory usage
+[[inputs.swap]]
+  # no configuration
+```
+
+### Metrics:
+
+- swap
+  - fields:
+    - free (int)
+    - total (int)
+    - used (int)
+    - used_percent (float)
+    - in (int)
+    - out (int)
+
+### Example Output:
+
+```
+swap total=20855394304i,used_percent=45.43883523785713,used=9476448256i,free=1715331072i 1511894782000000000
