有一个 bunyan 日志，这是一个示例条目

[2016-05-31T15:38:47.889Z] FATAL: jklajsd-utilities/23399 on aaa.bbb.ccc.com: 
    0: {
      "code": "EADDRINUSE",
      "errno": "EADDRINUSE",
      "syscall": "listen",
      "address": "0.0.0.0",
      "port": 5566
    }

好的，我想找到那个之后的所有条目：

bunyan /opt/aaa/.pm2/logs/cccc-out-15.log -c 'this.date >= new Date("2016-05-31T15:38:47.889Z")'

没结果。也试过了this.time。bunyan 文档说这time是正确的字段，但它不起作用。new Date("2016-05-31T15:38:47.889Z")'已验证：

> new Date("2016-05-31T15:58:50.475Z")
Tue May 31 2016 08:58:50 GMT-0700 (PDT)

日志过滤肯定有效：

$ bunyan /opt/aaa/.pm2/logs/cccc-out-15.log -c 'this.level === DEBUG ' |wc -l 
102455

$ bunyan /opt/aaa/.pm2/logs/cccc-out-15.log -c 'this.level === FATAL '|wc -l 
1679

将年份更改为 2015 年并没有做任何事情。

那么我在日期过滤方面做错了什么？

JSON 中的时间存储为字符串。因此，您需要在比较之前对其进行转换。

bunyan /opt/aaa/.pm2/logs/cccc-out-15.log -c 'new Date(this.time) >= new Date("2016-05-31T15:38:47.889Z")'

答案似乎是在调用 bunyan 之前进行过滤：

cat /opt/xyz/.pm2/logs/whiskey-tango-out-15.log | grep "2016-10-11" | bunyan -o short

产生：

为我工作。似乎它应该可以使用 bunyan 命令行。
