检查进程启动情况，开始时间、启动时间、启动进程数、进程数是否正确、PID

#!/bin/sh
bin=$(cd `dirname $`;pwd)
cd ${bin}

### 定义检查函数
chk(){
    programName=$
    correctNum=$
    programSubName=$

    # 判断是否带子程序名
    if [ -n "${programSubName}" ]
    then

    # 解析进程信息
    pid=${info[]}
    startTime=$(date -d "${info[1]} ${info[2]} ${info[3]} ${info[4]}" "+%Y-%m-%d %H:%M:%S")
    elapsedTime=${info[]}

    # 判断进程数是否一致
    if [ ${programNum} -eq ${correctNum} ]

        printf "${format_str}" "${program}" "ok" "${startTime}" "${elapsedTime}" "${programNum}" "${correctNum}" "${pid}"
    else

}

### 打印表头
format_str="%-33s %7s %20s %14s %12s %12s %10s\n"
printf "\n${format_str}" "ProgramName" "Status" "StartTime" "RunningTime" "ProgramNum" "CorrectNum" "PID"

### 检查Client进程
for i in `cat canalInstance`
do
    chk "CanalClient"  ${i}
done

### 检查Server进程
chk "AAAAAAAAAAAAAAAAAAA"  aaaaaaaa_00
chk "BBBBBBBBBBBBBBBBBBB"  bbbbbbbb_01
