禁用glog的“LOG（INFO）”日志 [英] Disable glog's "LOG(INFO)" logging

问题描述

我试图优化我的c ++程序。它使用caffe。

当执行我的程序时，caffe每15分钟输出大约1GB（！）的信息日志。我怀疑这影响效率显着。但我还没有找到如何关闭日志。在此问题中，有人建议您将 FLAGS_v 手动。

I'm trying to optimize my c++ program. It uses caffe.
When executing my program, caffe outputs around 1GB (!) of info logs every 15 mins. I suspect this impacts efficiency significantly. But I haven't found how to turn logging off. In this question someone suggested setting FLAGS_v manually.

使用以下代码，我可以按级别禁用日志，但<$ c

With the following code I can disable VLOG logs by level, but LOG(x) logs are unaffected.

中的第一行main（）：

FLAGS_v = 1; //disables vlog(2), vlog(3), vlog(4)
VLOG(0) << "Verbose 0";
VLOG(1) << "Verbose 1";
VLOG(2) << "Verbose 2";
VLOG(3) << "Verbose 3";
VLOG(4) << "Verbose 4";
LOG(INFO) << "LOG(INFO)";
LOG(WARNING) << "LOG(WARNING)";
LOG(ERROR) << "LOG(ERROR)";

输出：

WARNING: Logging before InitGoogleLogging() is written to STDERR
I0523 19:06:51.484634 14115 main.cpp:381] Verbose 0
I0523 19:06:51.484699 14115 main.cpp:382] Verbose 1
I0523 19:06:51.484705 14115 main.cpp:386] LOG(INFO)
W0523 19:06:51.484710 14115 main.cpp:387] LOG(WARNING)
E0523 19:06:51.484715 14115 main.cpp:388] LOG(ERROR)

code> flag 我不知道？我想要评论每个 LOG（INFO）行，但我想要一个更优雅的解决方案。 （我想在命令行标志解决方案上的c ++解决方案）。

Is there another flag I'm unaware of? I'm thinking of commenting every LOG(INFO) line out, but I would like a more elegant solution. (I'd prefer a c++ solution over a command line flag solution).

推荐答案

您需要设置您的环境变量

you need to set your environment variable

GLOG_minloglevel=2

$ b b

然后运行您的可执行文件。

then run your executable.

您可以找到更多信息这里（在这个页面的底部有一个关于从你的代码中使用宏定义剥离 LOG（） ）。

You can find more information here (at the bottom of this page there is a section on stripping LOG()s from your code using a macro definition).
