Heroku:查看日志中的参数和 sql 活动? [英] Heroku: see params and sql activity in logs?
问题描述
当我在服务器上查看我的 heroku 日志时(使用 heroku logs --tail --app myapp)，我看到如下内容:
When i view my heroku logs on the server (with heroku logs --tail --app myapp) i see something like this:
2011-06-21T14:09:25+00:00 app[web.1]: Started PUT "/reports/19.xml" for 77.89.149.137 at 2011-06-21 07:09:25 -0700
2011-06-21T14:09:25+00:00 heroku[router]: PUT myapp.heroku.com/reports/19.xml dyno=web.1 queue=0 wait=0ms service=7ms status=401 bytes=28
2011-06-21T14:09:26+00:00 heroku[nginx]: PUT /reports/19.xml HTTP/1.1 | 77.89.149.137 | 656 | http | 401
在我的本地日志中，我会看到如下内容:
While in my local log i'd see something like this:
Started PUT "/reports/19" for 127.0.0.1 at 2011-06-21 15:27:01 +0100
Processing by ReportsController#update as XML

即包含更多信息，特别是参数、来自路由器的信息、生成的 sql、呈现的任何模板等.
Ie with a lot more information, particularly the params, info from the router, generated sql, any templates rendered etc etc.
有谁知道如何让我的 heroku 日志像我的开发日志一样冗长?我已经完成了以下操作:
Does anyone know how i can get my heroku log to be as verbose as my development one? I've done the following already:
1) 在相关(rails 3)环境文件中设置日志级别:
1) Set the log level in the relevant (rails 3) environment file:
config.log_level = :debug
2) 告诉 heroku 使用不同的记录器级别，如 http://devcenter.heroku.com/articles/logging 中所述
2) Told heroku to use a different logger level, as described on http://devcenter.heroku.com/articles/logging
heroku config:add LOG_LEVEL=DEBUG --app myapp #from CLI
两者都没有任何区别......任何人有什么想法吗?
谢谢，最大
Neither has made any difference...any ideas anyone?
thanks, max
推荐答案
您实际上希望在 Heroku 日志中显示 SQL/params 输出.您可以通过将下面显示的行添加到 production.rb 文件中的 config 块来实现:
You're essentially wanting to show the SQL / params output in the Heroku logs. You can do this by adding the line shown below to the config block within your production.rb file:
MyAppNameHere::Application.configure do
# add this line
config.logger = Logger.new(STDOUT)
end
顺便说一下，将日志级别设置为 debug 只是意味着 Rails.logger.debug 将在您使用 Heroku 时输出到日志
By the way, setting the log level to debug just means that Rails.logger.debug will output to the logs when you're on Heroku
