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. We are trying to move our Seq instance from a Windows VM (service installation) to Kubernetes (using the latest v. 5.x image from docker). In this process we need to install a custom Seq app from our own Nuget feed (using Myget). When adding this app in a Seq instance using docker, we keep getting errors. I'm including stack traces below. Installing the same app on a Seq instance running on a local machine as a Windows service (exact same Seq version), works perfectly. Stacktraces: Without providing a version (which states it defaults to latest): ``` Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: Cannot perform runtime binding on a null reference at CallSite.Target(Closure , CallSite , Object ) at System.Dynamic.UpdateDelegates.UpdateAndExecute1[T0,TRet](CallSite site, T0 arg0) at Seq.Server.Features.Installation.NuGet.PackageRepositoryV3.FindLatestVersionAsync(String packageId, Boolean allowPrereleaseVersions, Boolean allowUnlisted) at Seq.Server.Features.Installation.AppPackageStore.GetOrInstallAsync(NuGetFeed feed, String packageId, String version, Boolean force) at Seq.Server.Features.Installation.AppPackageInstaller.DownloadAndInterrogateAsync(String nuGetFeedId, String packageId, String version, Boolean force) at Seq.Server.Features.Installation.AppPackageInstaller.InstallPackageAsync(String nuGetFeedId, String packageId, String version) at Seq.Server.Web.Api.AppsController.InstallPackage(String feedId, String packageId, String version) ``` With an exact version: ``` Unable to install package "SeqToAzureQueue" v"2.0.0" from "nugetfeed-16" Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: <.

I know how to configure the SEQ server to retain events until some constant amount of time has passed. Is it possible to customize this further? As an example, suppose both events from staging and production went to the same server. I can easily distinguish these events by enriching them with an environment key (with value "staging" or "production" respectively). Is it possible for me to configure a shorter retentions for the events from staging and a longer retention for the events from production?

Hi, Could you please clarify how to use Serilog + Seq in the AWS Lambda Function. I've done configuration: private static void ConfigureLogger() { var levelSwitch = new LoggingLevelSwitch(); Log.Logger = new LoggerConfiguration() .MinimumLevel.ControlledBy(levelSwitch) .WriteTo.Seq(seq_url, apiKey: seq_apiKey, controlLevelSwitch: levelSwitch) .CreateLogger(); } Also tried to call Log.CloseAndFlush() at the end of my func and still no results.

We have a number of different projects feeding into our server so generally start our search with something like `ProjectId="ABC"`, then find the property value we're looking for e.g. `UserName` -which is appended to all events. Selecting it clears the filter bar and replaces it with just `UserName="xyz"` which is ok but it would be better if you were further refining the current filter rather than resetting it i.e. it would be `ProjectId="ABC" && UserName="xyz"`

Love the new "Search FROM timestamp" and "Search TO timestamp" -it's really handy when trying to timebox a set of issues but it would be better if it only updated the relevant date field (at the moment it clears the other one i.e. "FROM" clears "TO"). Scenario: 1. I filter the rough time period from/to to the nearest hour I know the issue was 2. I find the last message I'm interested in after scrolling down so select "Search TO timestamp" -the "FROM" clears 3. I re-input "FROM" and find the start of the time period so set the "Search FROM timestamp" and the TO is cleared

A lot of the time when looking through logs for something else you spot something you'd like to send to a dev (or while discussing an issue). It would be great if you could "Copy link to clipboard" -similar to the "Find just this" or "Permalink" but they don't hit the mark: "Find just this" - updates the current view which is a pain while you're investigating things "Permalink" - means the event is around forever which you may not want

Hello, we are running Seq in a Docker container. As we saw issue probably related to memory issue we wanted to configure `cache.systemRamTarget` by setting the `SEQ_CACHE_SYSTEMRAMTARGET` environment variable. It was still crashing and so we did change `Seq.json` and since then it seems to be running stable. Is there a way to check the actually applied Seq configuration running in Docker? I just want to validate if the environment variable was overriding the configuration as expected.

I have seq setup on our production web server. I have two applications sending to it, one works the other does not. I can log to seq to that server FROM my local machine, but when I run the application from the server it does not log.

I had a problem with the installation of SEQ. It didn’t install at the server due to error message. I found a workaround for it; It seems that the error was caused by the fact that the server was using Dutch regional settings. After changing the region to “English – US” the problem was “bypassed” and SEQ started working. Not a nice solution. Please advise. Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array. at System.Globalization.CultureData.GetNFIValues(NumberFormatInfo nfi) at System.Globalization.NumberFormatInfo..ctor(CultureData cultureData) at System.Globalization.CultureInfo.get_NumberFormat() at System.Globalization.NumberFormatInfo.get_CurrentInfo() at Seq.Server.Cli.Features.ListenUrisFeature.<Enable>b__6_0(String v) at Seq.Server.Cli.Platform.Option.Invoke(OptionContext c) at Seq.Server.Cli.Platform.OptionSet.Parse(String argument, OptionContext c) at Seq.Server.Cli.Platform.OptionSet.Parse(IEnumerable`1 arguments) at Seq.Server.Cli.Platform.Command.Invoke(String[] args, TextWriter cout, TextWriter cerr) at Seq.Server.Program.Main(String[] args)

We are using Serilog.Sinks.Seq to send events to Seq Server, we are planning to upgrade to latest version of Seq which would cause the server to become unavailable. When the Seq server becomes unavailable, how long will our apps hold onto log events (and how many) before they start being lost forever?

Hello, I'm using GELF Input in seq and everything is working fine. But after 48 hours interval GELF input stops processing any new events. When I restart seq service new events start show in seq again. This process is repeating, I must periodically restart seq service to keep GELF Input working. Is there any options how to detail log GELF Input app to debug why after some time stop processing incoming messages?

Can I get some clarification on afterID and startAtID? Based on what I'm seeing it looks like afterId actually means "events that occurred chronologically 'before' event x". is startAtId synonymous with afterId or is it opposite (meaning you find events occuring 'later' than startAtId)?

I love the ability to "drill" into a log event's nested JSON, for example if I click on the Charges element below, it expands to show me all the charges in the list. Very cool. {... ChargeDate: "2019-05-03T00:00:00.0000000", DefaultDueDate: "2019-05-01T00:00:00.0000000", ResponsibilityType: "Sole",, AmountMethod: "FixedAmount", Amount: 10, Multiplier: null, BillingDistSetting: {…}, Distributions: […], Charges: […] ...} But, when I view that list of charges, its just a wall of JSON. It would be helpful if there was a better data visualization story to make it easier to read. Maybe a tree view of the json.

Hi, I was using the docker version of Seq but found I would like to change the Raw Payload Maximum Content Length & Raw Event Maximium Content Length settings (which can be found in system settings) Is there any way of doing this somehow without actually going to the system settings page manually, but configure this in a docker-compose or startup script? Thanks in advance, Vincent

We log all messages with a correlation id and I need to see the first 100 messages for a specific correlation Id. I have a signal for the Correlation Id filtering and then I'd like to be able to do something like.. select @Message from stream order by time desc limit 100 but this won't work due to restrictions on usage of time. Id won't work either.. so is there any way to accomplish this?
