作用
新增进程采集器ProcessCollector
新增指标
系统级别
vm_process_minimum: 多值体系下的系统内进程数最小值
vm_process_maximum: 多值体系下的系统内进程数最大值
vm_process_average: 多值体系下的系统内进程数平均值
vm_process：系统内进程数，pid数
进程级别
process_cpu_average: 多值体系下的某个进程的cpu利用率平均值
process_memory_average： 多值体系下的某个进程的内存利用率平均值
process_openfile_average： 多值体系下的某个进程的打开文件数的平均值
process_number_average ： 多值体系下的某个进程的线程数平均值
process_number_maximum： 多值体系下的某个进程的线程数最大值
process_number_minimum ： 多值体系下的某个进程的线程数最小值
process_expand封装
process_expand_cpu_percent： process_expand 封装，某个进程的CPU利用率
process_expand_memory_percent： process_expand封装，某个进程的内存利用率
process_expand_openfile_number：process_expand封装，某个进程的打开文件数
tag:
name：进程名
user： 进程用户
path：进程所在路径
args：运行参数
指标计算方法
CPU利用率
通过解析/proc/pid/status文件，解析cutime，cstime，utime，stime
user = utime + cutime
sys = stime + cstime
totalTime = user + sys
pid_cpu_percent = totcalCPUDiff/timeDiff;
totcalCPUDiff = (this_cpu_total - prev_cpu_total)/ hz
timeDiff = （本次采样时间-上次采样时间）
内存利用率
解析/proc/pid/statm
Resident = statm_resident * pagesize
pid_mem_percent = Resident / totalMemory
文件数
检查/proc/pid/fd
找出fd文件夹，计数
