Welcome to the Seq documentation hub. You'll find comprehensive guides and documentation to help you start working with Seq as quickly as possible, as well as support if you get stuck. Let's jump right in!
Hi Team, We have few dashboards which we need to showcase for regular monitoring and these should be login free, so please let us know how can we implement this. I have seen the details in the website where using api key its possible, I have created a API Key and added to the dashboard URL but still its asking for login user id and password. PLease let me know if I am missing anything. Thanks & Regards, Sarfraz.

I'm writing a Serilog sink for NATS. I'm using the information found in the links below but nothing covers the lifecycle of a sink. If I implement IDisposable will the logger dispose of my sink for me? https://github.com/serilog/serilog/wiki/Developing-a-sink https://github.com/serilog/serilog/wiki/Lifecycle-of-Loggers P.S. I'm aware of Serilog.Sinks.NATS but I want a client that uses the official Synadia supported NATS client ( https://github.com/nats-io/nats.net ). I also don't want it to use PeriodicBatching. Additionally I couldn't get it to work regardless.

I have an older installation of seq running version 4.1.17, unfortunately I only found migration guides to 5.0 when migrating from 4.2. (and then I suppose I just migrate to 5.1 in the second step) (https://docs.datalust.co/v5.0/docs/upgrading-from-seq-42) However I was unable track version history between 4.1.17 and 4.2. Could I just use the above migration guide to migrate to 5.0 from 4.1.17? Maybe there is an archived doc version somewhere I might have missed? Any help is much appreciated.

Hi. I am back again with another question. My problem is that I can't refactor every application we have, but I would like the benefit of getting the log-statements into SEQ. There is already a small windows service for collecting and forwarding log-statements from the event-viewer and it works brilliantly. My question is: Is there anything like that for monitoring text files in a folder and forwarding changes to these to SEQ? Thanks for an awesome product. It has saved my bacon a number of times :-)

I'm using the compact json formatter and serilog file writer to migrate my old logs to our new Seq server. It works but I would like the events to get logged in our Seq system with the original request times so they are searchable by the original timestamp and not the import time. Is it possible to override the @t value somehow? I tried simply putting a property enricher on but it gets encoded as @@t when actually serialized. Here's my configuration. _logger = new LoggerConfiguration() .MinimumLevel.Is(LogEventLevel.Verbose) .Enrich.WithProperty("System", "Legacy Mobile API") .Enrich.FromLogContext() .AuditTo.File(new CompactJsonFormatter(), $"C:\\Temp\\Mobile_Archives\\output_{Environment}_{DateTime.Now:yyyyMMddHHmmss}.logs") .CreateLogger();

I'm trying out Seq and have installed it in AKS. Things work fine with an ephemeral datastore, but when I configure /data to be a PersistentVolume (using pvc) seq refuse to start. The log says: ``` [12:06:27 INF] Seq "5.1.3200" running on OS "Linux 4.15.0-1056-azure #61-Ubuntu SMP Fri Aug 16 02:17:38 UTC 2019" [12:06:28 INF] Seq listening on ["http://localhost/", "http://localhost:5341/"] [12:06:28 INF] Opening document store "/data/Documents/documents.lmdb" [12:06:29 INF] Opening event store at "/data/Extents" [12:06:29 INF] Available storage engines in order of preference are ["FLARE"] [12:06:29 INF] Applying migration "Create the built-in roles" [12:06:29 INF] Applying migration "Create the server license" [12:06:29 INF] Applying migration "Create the Administrator account" [12:06:29 INF] Applying migration "Configure the public NuGet feed" [12:06:29 INF] Applying migration "Store the default system configuration" [12:06:29 INF] Applying migration "Ensure the license supports this version" [12:06:29 INF] Closing document store [12:06:29 INF] Closing event store [12:06:29 ERR] Uncaught exception from worker "Start background processes" ("f0516384-e1e6-4d2a-aadd-94ea4fa8b0b4") ... ``` And further down the stacktrace: ``` ---> Quince.NotFoundException: A document with id `license-server` was not found. ``` I've verified that seq writes data to the pvc, but I cannot find a license file

Hi, I noticed I was getting errors related to memory usage (same as this issue: https://github.com/datalust/seq-tickets/issues/835). On about 4GB of RAM, Seq was using a bit over 3GB and was logging the memory allocation error. I have sinced upped the RAM to 8GB and Seq is now using 3.8GB and not logging memory allocation errors anymore. Question is: is this kind of memory usage normal? Should I be limiting the available memory to the container? Thanks, Yohan

Hi! Is there a function equivalent to SQL's COALESCE? It can be useful, for example, in case you have an aggregate operator (like mean) grouped by time, during which one interval might not have any event, so I would like it to return 0 instead.

Hi, we have quite old versions of seq running on our test (v3.4.18), acceptance (also v3.4.18) and prod (4.1.17) environments. The test and acceptance environments are still on a Windows Server 2008 R2, the prod environment uses Windows Server 2016 release. This is absolutely not how it should be. But now I want to correct the situation, and put all three environments on similar machines, with upgraded versions of Seq. For test and accceptance, I am fine losing all the data. But production, I want to make sure that the data is preserved. Any specific recommendations for me? Steps I think I would need would be: 1- copy the seq prod environment to a new seq acceptance environment, idem seq test environment 2. then migrate/upgrade test, migrate/upgrade accept, and if all this has worked fine, migrate/upgrate prod Anything you think I should think of? Kind regards, Nancy

I am logging events using Seq nlog target via http and also the same events to local json file in corresponding CELF format. After seqcli ingestion of the same file I've got all entries duplicated, but event id @i is the same. How override/skip duplicated ones ? Thanks.

Hello We are moving one of our seq instances to another machine. We did a full setup, backup on old box then restore on new one. All configuration (apparently) restored properly, but we noticed a thing in App's config. We have an Email+ app configured. But in it's status it says "The app host process is stopped". Any hints how to deal with this? Is it something to worry about or it will be working when events will be flowing in? Thanks Val
