Memory usage of Seq

Hi , I using Seq 2.4.2 as single user and it's very good. I have noticed that memory usage is always quite high. On average its around 2.3GB a lot of times its been on 5GB and for a little while it was around 11GB. Is there a way of restricting memory usage. Looking at he stats Rate accepted/arrived (last minute) 701/701 Working set (bytes) 2153771008 Threads 54 User thread pool threads available 32764 IOCP thread pool threads available 998 Memory utilization 44% Free space (bytes) 250435215360 cheers Greg O

Serilog is not writing log to Seq until Log.CloseAndFlush() is invoked

Serilog and Seq works fine when I log from WinForm/web application. I am facing problem only when I am using console application. Without writing Log.CloseAndFlush() it is not working. Following is my LoggerConfiguration Log.Logger = new LoggerConfiguration() .WriteTo.Seq("http://localhost:5341") .CreateLogger(); Is there any way to log without invoking Log.CloseAndFlush() so that it works with seq, serilog in console application. Do I need to call Log.CloseAndFlush() everytime after logging? If I have a console application who listen a queue and do some operation, on that case where I will invoke Log.CloseAndFlush()? Expecting your help.

Troubleshoot no logging using Serilog

Hi folks, I'm having a hard time with SeriLog & Seq. I did a fresh new install of Seq UI on my dev machine. Created a dummy Console app. Logger config is stored in app.config. The events logged by the console app are showing correctly in Seq. Then I try the same thing in my web application. Same config settings stored in the web.config and same events logging code. But Seq UI stays empty.... Tried to enable the SelfLog to log in the console while debugging but I get no message there either. Any clue about how to troubleshoot this if calling Log.Debug(... does not generate any exception and SelfLog does not show anything ? Thanks,

Logging object properties with nlog

Hi Trying to log properties so they are searchable using NLog. I know I can use @ to serialize objects in messages - but how to do the same for properties? Pseudo c# code that works (I can e.g. search for x.status=0 ): class MyClass { public int status { get; set; } }; var x = new MyClass(); log.Debug().Message("Write {@x}", x).Write(); Pseudo c# code no working (only x class name is serialized): class MyClass { public int status { get; set; } var x= new MyClass(); log.Debug().Message("Write Hi").Property("x", x).Write(); How do I make MyClass serailized so I can search i when logging it as a user Property Regards

Can I install as an Azure Web App?

I'd love to run Seq on Azure, but I don't want to spin up a whole VM for it, especially since I'm already paying for a Web App. Can I install it as a Web App (i.e. running on IIS) or do I have to install it standalone?

Single quotes in query string

My team are trying out Seq, one of the issues that we are facing is when sharing links for filtered results the query string contains single quotes which when pasted into something like Slack the trailing quote is ignored. Presumably it is expecting the single quote to be escaped as %27. /#/events?signal=(signal-17~signal-15)&filter=CorrelationId%20%3D%20%2798df009c-681c-4e6f-93c8-29eaa0ef8a10' Is there a way to resolve without waiting for a code fix?

Error: "Seq is unavailable. Failed to initialize storage: Primary index is corrupt. The database must be defragmented or the table deleted."

What do I need todo to fix this? I have removed seq restarted reinstaled etc.

How do I install Seq Apps on server using a proxy

Hi, I'm trying to install Seq.App.EmailPlus. This seems to work fine on my dev PC. I also want to install it on the Seq server we use it production but installation is failing. After clicking the 'Install' button the UI waits for 20 seconds and then shows the error message : "Could not install app An error occurred while loading packages from'https://www.nuget.org/api/v2/': Unable to connect to the remote server'". I checked Seq's log and can see an error around the same time, which starts with the line: "System.InvalidOperationException: An error occurred while loading packages from'https://www.nuget.org/api/v2/': Unable to connect to the remote server ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 191.236.146.247:443" Our production server requires a proxy server for outbound connections. Is it possible that Seq can't do the install because it's having problems connecting through the proxy? Is there another way of installing that doesn't pull the package directly from nuget? Thanks, Simon.

aspnet core -> seq over SSL with self signed certificate

So I've setup a separate VM in azure and bound port 443 to seq, from my local machine I can write to it just fine since I've added my own CA to my machines trusted root cert store. Once I deploy to azure I can't log. I'm guessing it's since I'm using a self-signed cert and I can't install certs to the trusted root store for azure websites. And I really want my logging application to run in an azure website. To the question: is it possible to configure serilog to not validate the certificate chain? Perhaps point out my own request handler where I set the validation callback to always return true?
