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!
I've got an automated powershell script for returning some information from SEQ events. It's been working fine with Seq 3.4.20 but I'm having a problem this morning I can't figure out. The short question is: I enter a filter in the Seq UI and press enter. I can see the URL in my browser window changes and I see the URL-encoded filter for this particular query. Here's an example: https://some.domain.name/#/events?filter=Id%3D%3D%22dc4c45b9-8d33-4b53-8fe6-ed9c23ebacf7%22%20%26%26%20SOAPResponse%20!%3D%20null Which came from the filter: Id=="dc4c45b9-8d33-4b53-8fe6-ed9c23ebacf7" && SOAPResponse != null In the Seq UI, this returns one row. If I plug that same filter into an API query, I get an empty array: https://some.domain.name/api/events?filter=Id%3D%3D%22dc4c45b9-8d33-4b53-8fe6-ed9c23ebacf7%22%20%26%26%20SOAPResponse%20!%3D%20null As noted earlier, the powershell script that I've been using for months to build this query and pull back information from the API has been working. I don't see anything wrong with the syntax and the fact that the same filter works in the Seq UI has me even more puzzled.

Hello! I want to display the Seq log page in an iframe on my site page. But I got an error in the Chrome console: Refused to display 'http://***seqlog.url***/#/events' in a frame because it set 'X-Frame-Options' to 'deny'. Is it possible to somehow configure X-Frame-Options header so the Seq log site can be displayed inside an iframe? Thanks, Artem

I made a huge mistake months ago when setting up Seq to listen on 5341 for https instead of 443. I am finally getting sick of security guys repeatedly blocking outbound tcp 5341 and would like to set things up right by migrating to 443. Unfortunately, migrating all of my apps at once to 443 isn't practical, so I would like to have Seq use SSL on 443 and 5341 while I migrate everything to 443. The seq bind-ssl command help doesn't indicate that you can specify multiple ports and the seq install command help implies that it can listen on multiple URLs, but doesn't specify the syntax for multiple URLs. It just has a single URL sample.

I have a MVC application that uses Seq. When an exception occurs, I am redirecting it to the seq as an error but it doesn't show the full stack trace which is really hard to understand the exact place of the code that get failed. I am reading seq config from app.config file as follows; <!--Serilog--> <add key="serilog:minimum-level" value="Debug" /> <add key="serilog:using" value="Serilog.Sinks.Seq" /> <add key="serilog:write-to:Seq.serverUrl" value="http://localhost:5342" /> And then ILogger log;= new LoggerConfiguration() .ReadFrom.AppSettings() .CreateLogger(); And then invoke log.Error catch (Exception ex) { log.Error("Error updating student details. StudentId:{0} Message:{1} Trace:{2}", someid, ex.Message, ex.StackTrace); throw ex; } My seq out put as follows, Please note that the full stack trace with line lumbers are missing. 31 Mar 2017 01:31:39.470 Error binding the student model StudentId:0 Message:Value cannot be null. Parameter name: String Trace: at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number,… Id ▾ Level (Error) ▾ Type ($61C10FBB) ▾ Pin ▾ Raw JSON 0 0 1 Value cannot be null.

I am using serilog.sink.seq to push logs into SEQ (3.4.18), in batch mode. Once in a while, SEQ will reject a payload because it is bigger than max size. Whenever this happens, the SEQ UI will not display new incoming logs for 30sec to a few minutes (it seems the bigger the payload, the longer it hangs). While SEQ apparently hangs, I can see that my serilog sink is chugging away, it keeps sending to SEQ without any apparent errors. After the hang period, all logs that have been sent are now seen. Is there a way to avoid that, the issue is that when the rejected paylod is very big, it can take upwards of 5-10minutes for SEQ to "un-hang" - this tends to cause panic amongst people monitoring the logs as it seems like our logging system goes down. Thanks,

Hi, I've been using seq with a single user with our own domain (http://seq.ourdomain.com) with no problems at all. We recently decided to purchase a licence so we could add more users. After entering the licence whilst accessing seq externally, I got a 404 when trying to add an admin password and when refreshing the page I now get the default IIS welcome page. I can still access it fine on the server it is installed, but anywhere else I get the default IIS page. It's odd because it was working perfectly before adding the licence. Would you be able to help me out on this one as it seems to be quite unexpected behaviour after working so well. Thanks

Hi. Is it possible to do addition/subraction of numbers i query? I'm trying something like: select ToIsoString(Min(@Timestamp)) AS StartTime, ToIsoString(Max(@Timestamp)) AS EndTime, (Max(@Timestamp) - Min(@Timestamp)) AS TimeSpan from stream where ETLModule = 'Baseline' group by BatchId order by StartTime ASC The (Max(@Timestamp) - Min(@Timestamp)) gives me an error

I am using Dynamic Level Control with Serilog, in an MVC application and in 2 WebApi applications. In the MVC application it works. after some logs, the level switches dynamically. However in the WebApi applications the exact same code (it is in a library) doesn't work. The level never changes. So not every message will be visible in Seq. Since the Seq Sink uses HttpClient internally, is it possible that I've broken the dynamic level control because of some global filters? Would it be possible to break the functionality by altering the global httpconfiguration? Maybe that's why it doesn't work?

Is it possible in SEQ to combine the functionality of the filter syntax and the SQL queries? Or will there be support for it in the future? We want to be able to execute a select query for example: Select A,B,C From stream WHERE UserName='[email protected]' and when selecting an event, we want to be able to see all the properties of that event. In short, we would like to have a way to use a select when using the filter syntax.

When we try to make a new app instance run on all existing events we get the message: Could not save app instance Apps cannot currently run over existing events unless disk buffering is used. I can't find any reference to "disk buffering" anywhere else in the admin interface. All the best, Matthew

I am a software developer running a bank of system tests that are necessary to test Daylight Savings transitions. As such, the tests do a lot of changing of the system clock on my machine throughout the test run. Diagnostic logging is being done from the application into seq via Serilog. If I go to open the seq page, I get a license error: The single-user license only permits one user to access Seq. Log queries have been disabled for ten minutes; please close Seq on additional machines to remove this message and re-enable log queries. To try Seq in a team environment, please request a trial license certificate from the Seq website. There are no additional machines accessing the site, and no other users than myself. The only way I have been able to clear this message and re-enable queries is by uninstalling Seq and reinstalling it, which is very frustrating. I believe Seq is somehow reacting to the big time and date changes on the system in a way that is causing this issue. This has only started happening to me since I upgraded to 3.4.20 but I've since observed this behaviour in 3.4.18 too.

Is there a way to get at data within an array using the handlebars syntax? I've tried {{From.[0].Address}} but it doesn't work. However I can search for From[0]["Address"] = "[email protected]" and results come back fine. Am I getting the syntax wrong, or do arrays not work in email templates? Cheers!

EventFlow is every easy to connect multiple inputs and outputs. Is there a plan to support EventFlow for Seq? My scenario is the following, Serilog -> EventFlow -> Seq in a service fabric environment.

We have a number of test environments where we have SEQ installed. We use each SEQ server for applications we have in that environment. When creating API keys in each environment it would be useful to be able to keep the same key across all the instances of SEQ. is it possible to define the key when creating one or edit them afterwards?

Hey there, I'm trying to automatically deploy seq to a VM using Azure Resource Manager and a powershell script I found and adapted here: https://gist.github.com/bjcull/d566d237ed172ae9c524bc289c41eda9 Everything appears to install to the correct location, however the service cannot start. Please note that if I navigate to where seq lives and run "seq run" the application appears to start up for the first time correctly. The error I'm getting from the service (found in event viewer) is below: Application: Seq.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.ArgumentException at System.IO.Path.CheckInvalidPathChars(System.String, Boolean) at System.IO.Path.NormalizePath(System.String, Boolean, Int32, Boolean) at System.IO.Path.GetFullPathInternal(System.String) at Seq.Server.Cli.Features.StoragePathFeature.<Enable>b__26_0(System.String) at Seq.Cli.OptionSet+<>c__DisplayClass21_0.<Add>b__0(Seq.Cli.OptionValueCollection) at Seq.Cli.Option.Invoke(Seq.Cli.OptionContext) at Seq.Cli.OptionSet.ParseValue(System.String, Seq.Cli.OptionContext) at Seq.Cli.OptionSet.Parse(System.String, Seq.Cli.OptionContext) at Seq.Cli.OptionSet.Parse(System.Collections.Generic.IEnumerable`1<System.String>) at Seq.Cli.Command.Invoke(System.String[], System.IO.TextWriter, System.IO.TextWriter) at Seq.Server.Program.Main(System.String[]) This leads me to believe there's an invalid path somewhere, but I can't figure out where. When viewing the properties of the service, it has this as the path to executable: "C:\Program Files\Seq\Seq.exe" run --storage="F:\SeqData\" The seq.json file found in F:\SeqData has the following content: { "cache": { "systemRamTarget": 0.9 }, "diagnostics": { "internalLogPath": "C:\\ProgramData\\Seq\\Logs\\", "internalLoggingLevel": "Information" }, "api": { "listenUris": [ "http://localhost:80/" ], "ingestionPort": null, "corsAllowedOrigins": [] }, "storage": { "masterKey": "[removed for this question]" } } Any help would be greatly appreciated :) Cheers, Ben.
