1 2## TS解析htrace数据时间戳的规则 3ProfilerPluginData是所有proto格式数据插件的最外层message。 4其中包含多个时间戳。根据name字段反序列化的data字段中包含一个时间戳，一般为具体事件发生的时刻；另外tv_sec, tv_nsec号数据域组成最外层的时间戳，一般为端侧使用该插件采集数据上报的时刻。 5在一些需要精确展示事件时间的业务中, 采用的是data中的时间; 在一些周期性采集统计数据的业务(如：进程的内存数据)中使用的是最外层tv_sec, tv_nsec. 6message ProfilerPluginData { 7 string name = 1; 8 uint32 status = 2; 9 bytes data = 3; 10 enum ClockId { 11 CLOCKID_REALTIME = 0; 12 CLOCKID_REALTIME_ALARM = 1; // since Linux 3.0; Linux-specific 13 CLOCKID_REALTIME_COARSE = 2; // since Linux 2.6.32; Linux-specific 14 CLOCKID_TAI = 3; // since Linux 3.10; Linux-specific 15 CLOCKID_MONOTONIC = 4; 16 CLOCKID_MONOTONIC_COARSE = 5; // since Linux 2.6.32; Linux-specific 17 CLOCKID_MONOTONIC_RAW = 6; // since Linux 2.6.28; Linux-specific 18 CLOCKID_BOOTTIME = 7; // since Linux 2.6.39; Linux-specific 19 CLOCKID_BOOTTIME_ALARM = 8; // since Linux 3.0; Linux-specific 20 CLOCKID_PROCESS_CPUTIME_ID = 9; // since Linux 2.6.12 21 CLOCKID_THREAD_CPUTIME_ID = 10; // since Linux 2.6.12 22 }; 23 ClockId clock_id = 4; 24 uint64 tv_sec = 5; 25 uint64 tv_nsec = 6; 26 string version = 7; // "1.01" 27} 28 29## 解析不同插件数据使用的时间戳对照表 30<table> 31 <tr> 32 <td></td> 33 <td>对应的插件</td> 34 <td>对应的业务说明</td> 35 </tr> 36 <tr> 37 <td rowspan="4">使用ProfilerPluginData.data中的时间戳</td> 38 <td>ftrace-plugin</td> 39 <td>ftrace</td> 40 </tr> 41 <tr> 42 <td>hilog-plugin</td> 43 <td>hilog日志</td> 44 </tr> 45 <tr> 46 <td>nativehook</td> 47 <td>native_memory(malloc, free, mmap,munmap, 统计事件)</td> 48 </tr> 49 <tr> 50 <td>hidump-plugin</td> 51 <td>fps</td> 52 </tr> 53 <tr> 54 <td rowspan="6">使用ProfilerPluginData.tv_sec 和tv_nsec/td> 55 <td>memory-plugin</td> 56 <td>系统内存</td> 57 </tr> 58 <tr> 59 <td>network-plugin</td> 60 <td>网络</td> 61 </tr> 62 <tr> 63 <td>cpu-plugin</td> 64 <td>cpu占用率</td> 65 </tr> 66 <tr> 67 <td>process-plugin</td> 68 <td>进程内存</td> 69 </tr> 70 <tr> 71 <td>diskio-plugin</td> 72 <td>磁盘读写速率</td> 73 </tr> 74 <tr> 75 <td>hisysevent-plugin</td> 76 <td>hisysevent</td> 77 </tr> 78</table>
