    1.观察某个方法每秒的请求量/失败比例等信息
    monitor -c 1 com.gofun.datasync.rest.TestRest aa

    2.观察某个方法的入参
    watch com.gofun.datasync.rest.TestRest aa “{params[0]}”

    3.观察某个方法的入参和返回值
    watch com.gofun.datasync.rest.TestRest aa “{params[0],returnObj}” -b -s

    4.观察某个方法中的某个对象,或对象属性
    watch com.gofun.datasync.rest.TestRest aa “{params[0],target}” -b -s
    watch com.gofun.datasync.rest.TestRest aa “{params[0],target.carId}” -b -s

    5.在线反编译
    jad com.gofun.datasync.rest.TestRest

    6.观测某接口入参及返回值,并通道写入文件
    watch com.gofun.moncar.rest.MonCarRest getMileageVo “{params,returnObj}” -x 4 -b -s -n 100000 > /data/log/arthas_log/moncar_2.log &
