在系统优化-内存优化分析过程中针对不同策略需要统计内存变化，检验是否有效。修改一些策略可能影响系统性能，因此需要多方面对比评估，如cpu占有率、io变化情况、长时间运行内存变化情况等。
如果一个策略实施后，通过一次两次去查看各方面数据，显然是不准确和繁琐的。需要在一定时间内连续检查个方便性能的变化，并统计数据，对比采取具体措施前后性能的变化，也可以排除长时间运行，该策略导致运行一段时间后，整体性能较差。
采集的性能数据主要来自命令如下：
CPU方面：top、busybox mpstat –P ALL内存方面：dumpsys meminfoIO方面：busybox iostat全方面查看：vmstat应用log：在apk中增加添加关键节点logkernel方面：cat /proc/kmsg性能影响分析，涉及两个方面的脚本实现
抓取数据脚本数据统计分析脚本使用方式
在设备上创建/data/log/目录，并把权限改为777 mkdir /data/log chmod 777 /data/log 把cpu_mem.sh脚本放到/data/log目录,然后把脚本权限改为777 // 改权限 chmod 777 cpu_mem.sh 把要统计性能的apk运行起来，然后运行脚本；进入/data/log目录下，运行如下命令 // 命令根据实际需求选择 // usage: ./cpu_mem.sh 间隔时间（单位秒） 抓取时间（单位分） 停止抓取时间（单位分） // usage: ./cpu_mem.sh interval_time capture_time sleep_time // 有些命令需要循环执行才能抓取道数据，间隔时间就是循环的间隔；抓取时间为持续抓取时间；停止抓取时间是停止抓log一段时间后再开始新的一轮抓取，新的一轮log产生新的文件，方便统计系统持续运行不同时间段，性能是否有变化 // 命令1：间隔3秒抓取一次，抓取10分钟体停止 ./cpu_mem.sh 3 10 // 命令2：间隔4秒抓取一次 抓取20分钟 停止10分钟后再开始抓取 ./cpu_mem.sh 4 20 10 // 命令3：间隔5秒，一直抓取 ./cpu_mem.sh 5 interval_time：默认值为3s。当设置值小于3s，使用默认值；大于3s，使用设置值capture_time：大于0或者不设置sleep_time：大于0或者不设置抓取的log文件，如

可以把该数据使用execl导入txt文档数据的方法导入excel，输出曲线图，清晰的展现长时间运行性能变化
延伸使用
有些问题是频繁开关机导致，因此开机需要抓取log，该脚本可以通过vbs脚本结合CRT工具，系统开机运行该脚本，并统计开关机次数，vbs脚本如下
#$language="VBScript" #$interface="1.0" Sub main While 1 crt.Screen.WaitForString "Starting kernel" crt.Sleep 1000 crt.Screen.Send vbCr do Until crt.Screen.WaitForStrings("shell@rk3288:/ $",1) crt.Screen.Send vbCr loop crt.Screen.Send "su;echo 0 > /proc/sys/kernel/printk" & vbCr crt.Sleep 1000 crt.Screen.Send "./data/log/cpu_mem.sh&" & vbCr crt.Sleep 1000 crt.Screen.Send "logcat -v time" & vbCr crt.Sleep 60000 crt.Screen.SendKeys "^C" & vbCr do Until crt.Screen.WaitForStrings("root@rk3288:/ #",1) crt.Screen.SendKeys "^C" & vbCr loop crt.Screen.Send "reboot" & vbCr WEnd End Sub分析log，抓取数据，需要根据实际需要自行定制脚本，在固定的应用场景，脚本实现完成后，可以延续使用
把设备上抓取的log数据拿出来，放在linux服务器上（samba映射目录），使用各方面脚本分析或者使用总脚本全面分析。
summary_cpu.sh使用方式
./summary_cpu.sh cpu_201905061206.txt 或者 ./summary_cpu.sh top_201905061206.txt都可以分析出cpu\top的结果。
目前脚本分析了以下字段：TOTAL（总的cpu使用率变化）、cameraserver等cpu使用率变化
calc_cpu_item $file TOTAL ...... calc_top_item $file iandos calc_top_item $file cameraserver calc_top_item $file surfaceflinger calc_top_item $file system_server代码详见附件
其他方面统计方式同理
使用summary.sh分析统计各方面的log数据，给脚本传递的参数可以需要统计的任一方面的log文件，如
./summary.sh cpu_201905061206.txt 或 ./summary.sh mem_201905061206.txt 或 ./summary.sh logcat_201905061206.txt注意： kernel log没有做分析，主要用来记录在抓取数据阶段是否出现严重问题，或者出现严重问题，方便配合其他log分析问题
