+question: How to monitor RAM usage when running data pipelines locally?
+sort_order: 58

+
+Monitoring RAM usage when running data pipelines locally is important to prevent out-of-memory failures. The following steps show how to monitor memory on Windows with WSL (Ubuntu by default):
+
+1) Install Windows Subsystem for Linux with Ubuntu as the default distribution:
+
+```
+wsl --install
+```
+
+2) To see static memory usage (RAM) consumed up to the current time (within WSL):
+
+```
+free -h
+```
+
+3) To see memory usage in real time while a process is running (refreshes at your chosen interval):
+
+```
+watch -n 1 free -h
+```
+
+4) If you are using Windows, allocate resources to WSL by configuring the .wslconfig file in your Windows home directory (e.g., C:\\Users\\<your_user>\\.wslconfig). A simple setup:
+
+```
+[wsl2]
+memory=6GB           # Memory to be allocated
+processors=4         # Processors to be allocated
+swap=10GB            # Disk memory used to avoid crashes (slower but safer)
+```
+
+5) Restart WSL to apply changes:
+
+```
+wsl --shutdown
+```
