What does the data in memory usage statistics mean?

Question

Node.js

To analyze memory consumption, I installed memwatch-next .
It gives out a lot of interesting information, but I don’t understand what it means =)

{
  "num_full_gc": 17,
  "num_inc_gc": 8,
  "heap_compactions": 8,
  "estimated_base": 2592568,
  "current_base": 2592568,
  "min": 2499912,
  "max": 2592568,
  "usage_trend": 0
}

Please help me decipher the property. What is responsible for what and how to operate with them to debug the application.
