问题 I'm trying to add colored log output for boost::log under linux. I read the following and I tried this: #define MY_LOG_ERROR() BOOST_LOG_TRIVIAL(error) << "\033[1;31" MY_LOG_ERROR() << "This is an error log." but it gives me the result below: [2016-07-11 17:23:16.328435] [0x00007f15f03d6780] [error] [1;31This is an error log. How to properly add colored log output to boost::log? 回答1: The proper way to customize output with Boost.Log is to use formatters. To set a formatter you will have to

问题 Maybe it's just doesn't exist, as I cannot find it in pydoc. But using python's logging package, is there a way to query a Logger to find out how many times a particular function was called? For example, how many errors/warnings were reported? 回答1: The logging module doesn't appear to support this. In the long run you'd probably be better off creating a new module, and adding this feature via sub-classing the items in the existing logging module to add the features you need, but you could

问题 I've been reading the logback manual for 2 hours and still can't figure how to do what I need. It is as simple as the title says: I want to log only the errors to a file, and the other levels (including ERROR) to console. This is the root section of my logcat.xml file: <root level="TRACE" > <appender-ref ref="CONSOLE_APPENDER" /> <appender-ref ref="FILE_APPENDER" /> </root> The problem with this configuration is that it logs every level >= TRACE to both appenders. I could let the root with

问题 Heey! So I've recently been given the task to take a Laravel 5.2 up to 5.6. It seemed to be fine...until I tried to do a \Log::info() . Every time I run that, I get a big error, but at the end, it still prints to the log. I saw the 5.6 documentation on creating the config/logger.php . I took a fresh copy of it from github. The only thing I did after that was set an env variable for the LOG_CHANNEL to be single. Here's the error I get: [2018-03-02 08:28:59] laravel.EMERGENCY: Unable to create

问题 Imagine I have this web application based on Aiohttp: from aiohttp import web import asyncio import logging logger = logging.getLogger(__name__) async def hello(request): logger.info('Started processing request') await asyncio.sleep(1) logger.info('Doing something') await asyncio.sleep(1) return web.Response(text="Hello, world!\n") logging.basicConfig( level=logging.DEBUG, format='%(asctime)s %(name)-14s %(levelname)s: %(message)s') app = web.Application() app.add_routes([web.get('/', hello)]

问题 I was running a program, and it will output the progress bar to a file train.2.log . Here's a link to the file train.2.log, which looks like the following on terminal : This is line 1 Training ...
