request-ip | js module for retrieving a request 's IP address | Runtime Evironment library

I used Objection.js as ORM for my Nest.js app. I tried to implement global error handling for both Http exception and Objection Error (ORM / Database Error). Suppose I make a mistake inserting a same unique value, it would throw UniqueViolationError. But every time I throw error on the users.service.ts (users module service) part of the app, on the service the error still an instance of UniqueViolationError but on filters it became the instance of HttpExceptionError thus my filters won't work. Here is the full code :

I am trying to use NLog in my ASP.NET Core 3.1 app. I am trying to log my controller actions. Internal logs are created successfully. It means my nlog.config is read correctly.

I am injecting the logger into my controller and trying to log. But log file is not created. Tried so many things. Checked stackoverflow but couldn't find a solution.

If I put name "*" in my rule, it works, it creates log file named _logs.csv. But for my controller case it's not working.

Here is my nlog.config:

I am using NLog FileTarget to log messages in a file, which gets picked up by a filebeat to send to Kibana.

My messages are often multiline.

I have noticed that some messages show up clipped in Kibana, with only some of the lines on the multiline message.

For example, in the logfie I have something like this

I have a .NET Core 3.1 Web Service and use NLog 4.7.0 for logging. I am currently using file logging and a filebeat to get the messages from the log files to ELK.

I want to create a wrapper target for my FileTarget. The actual purpose is to merge all logs for a single web request into a single log message, but this is probably beside the point.

I want to inherit from NLog.Targets.Wrappers.WrapperTargetBase, but the Write(LogEventInfo logEvent) method is sealed. Does this mean I can only use async logging for WrapperTargets?

Does this affect how I set up my logging configuration? Note that I am using configuration file, rather than configuration API, for config.

My existing FileTarget is like this:

This post isn't really a question anymore; I just want to post this to help other people out in the future to avoid lost time.

Goal: Retrieve the client IP address and set some specific values based on certain octet in IP.

I was developing a react web-app for my company and needed to support three facilities. The three locations of-course existed in different geographical regions and had slightly different IP schema's.

I needed to set some session identifier based on an octet value from the client IP. To do so, I did the following steps.

1. Setup express route for user to hit on initial visit of app.
2. Get client IP and store in const/var.
3. Explode IP string by ".".
4. Perform If/Then or Switch to determine value of desired octet.
5. Set some session/logic within matching condition.

Thanks to express, the req object contains an ip key with the value of the requests IP address. We can utilize this or some other third party library to get the needed info. Of course there are better/more secure ways to do this, but this is a simple method I've researched and setup. Definitely thanks to community for helping me resolve my issue with this.

I use NLog for my application logging, every things goes right except UnhandledException. I use EventId as 1 for my other logs, for example for viewing a list. but when my application raises an unhandled exception, The produced log uses EventId 1 to show Unhandled Exception.

for better demonstration, I paste my codes here

Here is NLOG Config at nlog.config file

I have an ASP.NET 4.7 web project where there is a Quartz.NET scheduler implemented. I've read that Quartz.NET is using Common.Logging abstraction, but I don't know what it really means...

In order to avoid my default application log to be spammed from Quartz messages, I have configured programmatically the NLog settings, in the following way:

I am using NLog for logging. I need to log the IP address of the user who is opening the website.

For that purposes, I am using the aspnet-request-ip property of NLog. The documentation is here: https://github.com/NLog/NLog/wiki/AspNet-Request-IP-Layout-Renderer

My layout in NLog config looks like the following right now:

Below is my app.js code.
