When run with only a file, it will output the generation and count pairs:
|
||
|
|
|

|
|
$ heapy read tmp/2015-09-30-heap.dump
|

|
|
Generation: nil object count: 209191
|

|
|
Generation: 14 object count: 407

Generation: 15 object count: 638
|

|
|
Generation: 16 object count: 748
|

Generation: 17 object count: 1023
|
||
|
|
Generation: 18 object count: 805
|
||
|
|
|
||
|
|
When run with a file and a number it will output detailed information for that
|

generation:

$ heapy read tmp/2015-09-30-heap.dump 17
