#### 使用 -v 参数打印更多信息
> watch/trace/monitor/stack/tt 命令都支持 `-v` 参数
当命令执行之后，没有输出结果。有两种可能：
1. 匹配到的函数没有被执行
2. 条件表达式结果是 false
但用户区分不出是哪种情况。
使用 `-v`选项，则会打印`Condition express`的具体值和执行结果，方便确认。
比如：
```
$ watch -v -x 2 demo.MathGame print 'params' 'params[0] > 100000'
Press Q or Ctrl+C to abort.
Affect(class count: 1 , method count: 1) cost in 29 ms, listenerId: 11
