TraceStreamer 解析数据状态表

TraceStreamer使用stat表统计解析trace数据源过程遇到的重要事件状态。通过stat表可以对trace数据源中各个类型事件的数据的数量，数据质量有一个基本了解。
我们对不同类型的数据，统计了收到多少条，数据逻辑是否匹配，是否有不合法数据，是否有数据丢失情况，所有这些，是基于对数据格式本身和数据前后关系的主观认识。欢迎开发者提供更多的思路来帮我们完善数据本身的校验工作。

stat表支持统计的事件列表如下：

ftrace事件统计

网络数据事件解析

事件名称
trace_network

事件对应解析状态：

每种事件解析数据都有5种状态，描述如下表：

stat_type	description
received	统计trace数据源中总共有多少该事件。
data_lost	统计TraceStreamer解析过程中发现丢失数据条数。
not_match	统计有多少数据与上下文其他数据不匹配。
not_supported	统计有多少暂不支持解析该事件（一个事件可能包含多种类型的子事件， TraceStreamer可能支持该事件的一部分子事件）。
invalid_data	统计收到多少条该事件的非法数据。

数据状态级别

数据状态级别总共有4种，分别是：info, warn, error,fatal。由于数据的重要性不同，不同事件的同一种状态可能对应不同的级别。 例如binder_transaction_received的 not_supported状态的数据为info级别，而binder_transaction_alloc_buf的not_supported状态数据为warn级别。

您可以在src/cfg/trace_streamer_config.cpp的InitSecurityMap方法中自行定义相关事件的优先级。
