How to make a certain piece optional in a NLog layout pattern?

余生长醉 提交于 2019-12-04 07:05:46
I have a custom layout renderer named job . It provides several items, which are used like this in our app.config: <variable name="jobHost" value = "${job:item=host}" /> <variable name="jobService" value = "${job:item=service}" /> <variable name="jobNS" value = "${job:item=ns}" /> <variable name="jobName" value = "${job:item=name}" /> <variable name="jobKind" value = "${job:item=kind}" /> <variable name="jobScheduleId" value = "${job:item=scheduleId}" /> <variable name="jobLayout" value = "[H:${jobHost} S:${jobService} NS:${jobNS} N:'${jobName}' K:${jobKind} S:${jobScheduleId}]" /> <variable

Can NLog preserve callsite information through c# extension methods?

懵懂的女人 提交于 2019-12-04 05:35:46
问题 EDIT: While similar, this is not the same as the questions about using an NLog wrapper. Extension methods add another level of indirection which makes even a proper wrapper report the wrong callsite I currently use a logging wrapper around NLog, and I use the trick they show in the example in their source for getting accurate callsite info. For a new project I started, I wanted to create a simpler class, so I just implemented something like the following interface: public interface ILogger {

No Signs of Fatal Exception when application crashes | NLog version 2 | Compact Framework 3.5

|▌冷眼眸甩不掉的悲伤 提交于 2019-12-04 05:26:44
问题 I have a .Net Compact Framework 3.5 application that uses Nlog version 2.0 to log Info, Error and Fatal Exceptions. Most of the time the logging works as expected and logs fatal exceptions before crashing. But at times it is observed that application crashes without leaving any signs of an error/exception. Let me elaborate the scenario: The Application creates few threads, all the threads have try-catch block added at the beginning of their call stacks. And hence log fetal exceptions before

Using Stored Procedure in NLog on a Database target

旧街凉风 提交于 2019-12-04 05:07:01
I am having a bit of a problem using a stored procedure instead of a SQL INSERT statement when using NLog in a C# web application. The connection string "Logger" is correctly configured in Web.config and works properly when replacing the commandText with a SQL statement. I would appreciate a hint in the right direction. In this example the stored procedure is under the "Logs" schema and it is called "LogError". <targets> <target xsi:type="Database" name="dberrorlog" connectionStringName="Logger" keepConnection="true" commandText="[Logs].[LogError]" > <parameter name="@ProgName" layout=

How to log exceptions with network targets in NLog

别来无恙 提交于 2019-12-04 05:03:47
I am using the NLog logging framework and am trying to get exception and stacktrace information showing up in any UDP logger appliaction, such as Sentinel and Log2Console , but can only get the log message part displayed. Outputting to a file works well as most examples do just that, so the problem revolves around using network targets with NLog. Bonus if a custom format can be applied on inner exceptions and stacktrace, but this is not required. Exception.ToString() would go a long way. Note on the example code: With Log2Console I found an article on how to send exception as a separate log

How to use NLog in C++?

I have a simple native ++ console application in visual C++. In order to use NLog there is a mixed mode " "NLogC.dll" How can i add "NLogC.dll" to my application And use for logging? Simply how can i use Nlog in a native C++ Application? NLog includes a header file ( NLogC.h ) and import library ( NLogC.lib ). Those should be used to use the library. Add the path to the include file (e.g. C:\Program Files (x86)\NLog\.NET Framework 4.0\NLogC\include ) to the include path, either globally or for the project only. You can specify it in the project's properties under "Additional Include

How to set NLog's fileName to the process start date?

最后都变了- 提交于 2019-12-04 04:59:10
I tried <target name="txtFile" xsi:type="File" fileName="${date:format=yyyy-MM-dd HH-mm-ss}.txt" layout="${longdate} ${level} ${message}"/> but it creates a new file each minute. I realize that there is ${processinfo:property=StartTime} but I couldn't format it. I tried: ${processinfo:property=StartTime:format=yyyy-MM-dd HH-mm-ss} but it doesn't work Using the Cached Layout Renderer For a solution that doesn't require code, use the Cached Layout Renderer : <target name="txtFile" xsi:type="File" fileName="${cached:cached=true:inner=${date:format=yyyy-MM-dd HH-mm-ss}}.txt" layout="${longdate} $

Creating a database programatically in nlog to enable using DatabaseTarget

我只是一个虾纸丫 提交于 2019-12-04 04:39:43
问题 I'm creating a DatabaseTarget object in C# and using it to log data into an NLog database. If the database does not exist, the nlog target fails. I want to check to see if the DB exists, and if it doesn't create it and a log table. I can see the targetDB.Install(installationContext) function appears to be able to do the job but cannot find any examples. There are numerous examples using a config file. I want to put this in code and not have to deploy a config file in all applications that use

using Nlog and writing to file as json

我的梦境 提交于 2019-12-04 04:18:48
I think I'm missing something as I can't seem to figure out how to have it write to a log file in json format using NLog setup in configuration file. The straight rolling file works fine, but not the json. The json target only outputs the message (not in json). <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <targets async="true"> <target xsi:type="File" name="rollingFile" fileName="${basedir}/logs/${shortdate}.log" archiveFileName="${basedir}/logs/{shortdate}_Archive{###}.log" archiveAboveSize="1000000" archiveNumbering=

Getting NLog to send out JSON with proper headers?

别等时光非礼了梦想. 提交于 2019-12-04 03:15:46
Trying to use NLog to send JSON-encoded logs out of our C# app, to dump them into CouchDB. However, using the Network target, I can't seem to find a way to set the Content-Type header properly; and CouchDB won't have anything to do with my input otherwise. CouchDB is out-of-the-box, Current NLog config: <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" throwExceptions="true"> <variable name="FileLayout" value='{ "date":"${longdate}","level":"${level}","message":${message}}' /> <targets> <target name="logfile" xsi:type="Network"
