从堆转储中提取线程转储
[英]Extract thread dump from a heap dump
问题描述
I have a huge heap dump (around 12GB) and it will take forever to open it with MAT or jvisualvm .

The latest snapshot versions of Memory Analyzer (preview of 1.11) have the ability to discard objects on parse.内存分析器的最新快照版本（1.11 预览版）能够在解析时丢弃对象。 Having a discard ratio of 100% with a pattern of (?!. Thread).具有 (?!. Thread)模式的丢弃率为 100% 。 would discard all objects except those of a type with 'Thread' in the classname.将丢弃除类名中带有 'Thread' 类型的对象之外的所有对象。 That might speed up parsing, though the parsed dump would be nearly useless, but it would have a thread dump (but without thread names or local variables) which might be enough for your purposes.这可能会加快解析速度，尽管解析后的转储几乎没有用，但它会有一个线程转储（但没有线程名称或局部变量），这可能足以满足您的目的。
