Hi Milan. I recently discovered your channel and appreciate your extent of coverage in chosen topics. I also greatly appreciate how you separate the chapters/sections so I don't pause the video early on and look for "not hardcoing serilog config in programcs" elsewhere; because you've made it clear that it was covered in a future chapter. Cheers!
I really like Serilog. I started to use it in 2019. It has been really helpful and saved me a lot of debugging time. Thank you for adapting it to modern technology.
Interesting video, I love serilog. If you can make a video on serilog + elastic search (from a sink) + kibana (also from a sink), it would be pretty sick :)
I have just switched to serilog - I was using your video as starting point, so thank you. Hence I am by far no expert of the field. I have found cumbersome to work with the array-style configuration, especially when overriding from environment - as it needs indexing. There is however - since quite a while actually - a syntax that allows to use an object with descriptive keys instead. This takes advantage of how the configuration infrastructure works in dotnet. And the cool part is, that you can leverage this even further by compacting the overrides in environment-specific appsettings. Like this for example: "Serilog:WriteTo:Async:Args:configure:MyDescriptiveLogFileSinkKey:Args": { "retainedFileCountLimit": 1, "RollingInterval": "Infinite", "formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog" }, Quite simpler than providing the whole structure.
I was hoping you would show the details on using SQL Server and how to log to it, such as auto-creation of a log table, the columns to includes, etc. Maybe a future video??
Hey did you come across anything which helps us generate log table, it's columns and log our event in that table? Please it'll be very helpful if you have found something and if you'd share that
Milan, do you have the creation process of full projects on video? or even in a course? I'm a big fan of learning through doing ant not just watching, and watching you and repeating the process of building a complete project applying some patterns, principles and good practices, would be amazing, I would pay to see that and learn from your experience.
Hi Milan, I really enjoy your works, i mean you have demonstrated how easy it is to adapt to any programing construct. Please do you have a repo for these source codes. Thnk you again
I like to use preprocessors for my debug code. I can remove most of my debug code very easy once I'm done making changes. And then like he does I keep the warning and error debug active just by switching my define from "debug_verbose" to "debug_performance".
@@MilanJovanovicTech thank you, I also use regions to hide them a little bit better. My editor allows me to collapse the preprocessor section but it's two lines rather than one line with a region. On top of that, my code completion AI has learned that when I type '# Region D...' To finish it with exactly what I want to Debug and closes the region and everything, using the same debug format I use perfectly.
I know it's a old comment but may help someone that comes across this comment. Serilog does have a sink for Seq. It's NuGet package called Serilog.Sinks.Seq. I use Seq at my work it's really handy, we have about 25+ applications feeding into it. I'd also check out meziantou's analyser to prevent incorrect datatypes used. E.g. If your using OrderId and it's an integer and string. If your using OrderId > 10 then the string values that are greater than 10 won't display. However, if you use meziantou's analyser show as warning that it's logging unexpected type. Hope this helps others.
What is the use of using section when we already specifying the write to section? Is it like duplicate things? Why the using section seems to be a namespace?What else can be specified in the using section for the sync?

Great Video, Thank you, i have a question here, i see that you have set the Default loglevel to Information yet in the end of the video we can see in the log.text file debug logs being logged, why is that? Am i missing something here?
This is good but it also feels a bit light. For instance - in a production environment you'd implement masking on sensitive fields. I've tried 3 different libraries and NONE seem to remove the password and ssn correctly - from either the request logging or the global exception handler. For the time being I set that aside because I'm so annoyed with it.
@@GeoffSeeley Yup I've used that one. It didn't work so well for me. I mean, at this point either none of these work, or I'm implementing them wrong, or they don't do what I think they do. Should be interesting when I finally find time to drill down into it and find out which.
plz add relative video links in description. If we didn't watch then we can able to watch it.(You said previous video but which video we can't find in description or (i) button.)
Hi Milan, I came across with this exact configuration you are presenting here, however, I notice the logs are not show in the output window but in the console of the program itself. Looks like there is a specific configuration (Writeto(debug)). My question is, How did you manage to get those logs in the output window with the congiguration shown in this video?, Do you have additional settings in your debug pane from VS? Thanks in advance!
hey milan!! its great.. but i need logs to print in seperate folders for each controller. can you please help me out or make another video about serilog with indepth configurations. thanks 👍
Interesting video. But I noticed your application layer also uses Serilog while installing this package into api layer. How would you be able to do that? Your Application layer also installs Serilog, doesn't it?
Great video as always Milan. One question. I want more serious error logs to be written both in the console and in the file, but less important logs like information and events only to the console. How can I do that?
@@MilanJovanovicTech Thanks. I don't think you mentioned the feature belonging something outside of VS in the video. Either I missed that or the info is missing from the couple of logging videos I did watch. Thanks for the clarification.
@@MilanJovanovicTech you have to add the packages into the project as well as calling them from configuration. Install-Package Serilog.Enrichers.Thread Install-Package Serilog.Enrichers.Environment

Definitely a future video, going to cover a few Serilog Sinks

Working on a course right now! Should be out in July/August. There are a few "from scratch" videos, but nothing that goes 0 to hero
Great video Milan !
Thanks!
i've a question. I can put this logs in each endpoint? For example, I've a endpoint to update one list and when this list update create a log
Sure - if that information is important for you
@@MilanJovanovicTech that's great, ty man

Nice Video. Which theme are you using? Your color scheme are better and difference than as usual visual studio provides as default.
Dark theme + R# syntax highlighting

Thank you so much. Is it OK to have the logs in a database? And how so?
You can use one of the many DB sinks
I would suggest to add Request ID to logs and make them async configuring WriteTo to be async.
Serilog is async by design. It logs in-memory to a buffer and then flushes to the file in the background.
I was hoping you would connect it to a seq sink.
Is seq usually used in the industry a lot?
I'd say AppInsights is common with .NET
I know it's a old comment but may help someone that comes across this comment. Serilog does have a sink for Seq. It's NuGet package called Serilog.Sinks.Seq.

I probably left it at Debug while recording that part

Serilog.Enrichers.Sensitive looks like it does that, but I haven't used it personally. You can also use Filters to exclude an entire matching request.

I doubt any logging library will take care of that for you.
Thanks for this.
What about implementing Structured logging, using Serilog without the MediatR library? Do you have any good sources for this?
Just use the ILogger where you think fits
What would happen to the logging if MediatR failed?
plz add relative video links in description. If we didn't watch then we can able to watch it.(You said previous video but which video we can't find in description or (i) button.)
Hmm, that's a good idea
Hi Milan,
I came across with this exact configuration you are presenting here, however, I notice the logs are not show in the output window but in the console of the program itself. Looks like there is a specific configuration (Writeto(debug)). My question is, How did you manage to get those logs in the output window with the congiguration shown in this video?, Do you have additional settings in your debug pane from VS?
Thanks in advance!
No idea, really. It just works on my machine 😅 (I didn't do anything special, the logs always showed up in the Output window whenever I run apps)
hey milan!! its great.. but i need logs to print in seperate folders for each controller. can you please help me out or make another video about serilog with indepth configurations. thanks 👍
I'm not sure how that's doable, never needed it
@@MilanJovanovicTech I think its a bug 😂
Must've been a feature
Interesting video. But I noticed your application layer also uses Serilog while installing this package into api layer. How would you be able to do that? Your Application layer also installs Serilog, doesn't it?
ILogger is from .NET
Great video as always Milan.
One question. I want more serious error logs to be written both in the console and in the file, but less important logs like information and events only to the console. How can I do that?
I think you can set a specific LogLevel filter for each sink
@@MilanJovanovicTech Yep found and implemented it. Thank you.
How does one enable the highlighting of parameters in VS? I'm using the 2022 community edition.
This is a ReSharper feature
@@MilanJovanovicTech Thanks. I don't think you mentioned the feature belonging something outside of VS in the video. Either I missed that or the info is missing from the couple of logging videos I did watch. Thanks for the clarification.
Hey Milan. What is your VS Theme name?
VS dark theme + ReSharper syntax highlighting
Did you forget to add the enrichers that would have given you the machine name and thread id etc on each log?
No, they were added from the configuration. For some reason though, they weren't in the log. Strange.
@@MilanJovanovicTech you have to add the packages into the project as well as calling them from configuration.
Install-Package Serilog.Enrichers.Thread
Install-Package Serilog.Enrichers.Environment
@@stevehiggin Ah that could be it, yeah!
Do you have a github example?
I have a blog post about it with examples: www.milanjovanovic.tech/blog/structured-logging-in-asp-net-core-with-serilog
@@MilanJovanovicTech thanks Milan
Where can I find the log file?
You can configure where the output will be
How can I make the message variables green? 10:52
ReSharper
Is the "@" needed?
If you want to deconstruct that argument into JSON, otherwise ToString() will be applied
@@MilanJovanovicTech thanks!! Awesome videos!
thank you kind sir.
You bet
