How do I know if my SQL needs more memory?

To determine if more memory is needed for SQL, monitor the following Performance Metrics:

1. Buffer Manager/Buffer Node: Page Life Expectancy (PLE)
2. Buffer Manager: Buffer Cache Hit Ratio.
3. Memory Manager: Memory Grants Pending.
4. Memory Manager: Target Server Memory vs Total Server Memory.
