dmtracedump 是一种用于从跟踪日志文件生成图形化调用堆栈图的工具。此工具使用 Graphviz Dot 实用程序创建图形化的输出，因此您必须先安装 Graphviz，才能运行 dmtracedump。如果尚未生成跟踪日志并将其从连接的设备保存到本地计算机，请转到通过检测您的应用生成跟踪日志。
dmtracedump 工具以树形图的形式生成调用堆栈数据，其中每个节点表示一个方法调用。它使用箭头显示调用流程（从父节点到子节点）。下图显示了 dmtracedump 的示例输出。
dmtracedump 工具在 Android SDK 工具软件包中提供，并位于 android-sdk/platform-tools/ 下。
语法
dmtracedump 的用法如下：
dmtracedump [-ho] [-s sortable] [-d trace-base-name] [-g outfile] trace-base-name
然后，此工具会从 trace-base-name.data 和 trace-base-name.key 加载跟踪日志数据。

输出
图 1. dmtracedump 的屏幕截图
对于此图表中的每个节点，dmtracedump 都会显示以下信息：
ref callname (inc-ms, exc-ms,numcalls)
ref - 跟踪日志中使用的调用引用号inc-ms - 包含时长（在方法中花费的毫秒数，包括所有子方法）exc-ms - 包含时长（在方法中花费的毫秒数，不包括任何子方法）numcalls - 调用次数

The tool uses the Graphviz\nDot utility to create the graphical output, so you need to install Graphviz\nbefore running `dmtracedump`. If you haven't yet generated trace logs and\nsaved them from your connected device to your local machine, go to\n[Generate trace logs by instrumenting your app](/studio/profile/generate-trace-logs).\n\nThe `dmtracedump` tool generates the call stack data as a tree diagram, where each\nnode represents a method call.
