Step-by-Step Solution
Solution:
Step 1: Identify correct parameter for memory alarm
vm_memory_high_watermark.absolute sets memory alarm threshold in bytes.Step 2: Convert 500MB to bytes
500MB = 500 * 1024 * 1024 = 524288000 bytes, so set this value.Final Answer:
vm_memory_high_watermark.absolute = 524288000 -> Option BQuick Check:
Memory alarm threshold = bytes integer [OK]
Quick Trick: Use vm_memory_high_watermark.absolute in bytes for memory alarm [OK]
