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, I have received the SEQ "Professional License", how would I install this manually? Also I am interested in installing it via powershell, I've seen the previous posts "Provide license file during installing Seq using msi", and do not have a clear understanding of Step 4 in the reply: " This can be done using Powershell after the Seq service is installed and started, so: Install the MSI (assuming that you have automated this part) Start the service, using seq.exe start It may be necessary to wait a few seconds for the service to start up POST the license text to /api/licenses/license-server using a JSON body like: {"LicenseText":"Serial..."} "

Hi, I'm getting this error when I click over plus icon to add a new alert: vendor-1500420102219.min.js:2 TypeError: Cannot read property 'push' of undefined at e.value (seq-ui2-1500420102219.min.js:81) at e.value (seq-ui2-1500420102219.min.js:129) at fn (eval at compile (vendor-1500420102219.min.js:4), <anonymous>:4:194) at i (vendor-1500420102219.min.js:5) at p.$eval (vendor-1500420102219.min.js:3) at p.$apply (vendor-1500420102219.min.js:3) at HTMLButtonElement.<anonymous> (vendor-1500420102219.min.js:5) at Jt (vendor-1500420102219.min.js:1) at HTMLButtonElement.n (vendor-1500420102219.min.js:1)

On the main screen: http://localhost:5341/#/events I type "something" and hit enter, URL changes to http://localhost:5341/#/events?filter=something and the UI updates to show the correct log entries. I hit the back button and the URL changes back to http://localhost:5341/#/events but the UI doesn't update at all and "something" still shows in the search box. Running Seq 4.2.476 on 64bit Windows 10 Enterprise (build 16299) using 64bit Chrome 63.0.3239.132.

Hello, I'm trying Seq but I have problem about custom domain. I created windows server on Amazon EC2 and I installed Seq with http://seq.mydomain.com/ After I forwarded seq.mydomain.com to server IP on Amazon Route53. Now, when I ping subdomain, I'm getting corret server IP but I can not get respond from respond from seq.domainname.com. Best.

Hi there, I cannot see the settings menu in the header in our Seq install. My guess would be that my user account does not have admin privileges (despite the username being "admin"). The person who set this up is no longer with the company. Is there anyway I can elevate my account to admin privileges? I have access to the Seq command line on the server. I've tried resetting his password using "seq unlock -u username -p password" but I get the error "Could not reset the password: Cannot access file, the file is locked or in use". However, I am just guessing what his username is. Any help would be greatly appreciated, Josh

Hi, Is there an option to enforce query timeout for any query against the stored events? I know there is a setting in user preferences, but that only affects SQL queries. I would also like regular text based searches and signals to time out. The problem I would like to solve is that some of the users start a long running query that has 0 results, so basically Seq has to go through all the stored events (which gets slow once they need to be read off the disk). Then the users forget to cancel the query so it runs until completion, which can take several minutes, using a lot of server's resources.

Is it possible to freetext search over object properties if they are not part of @Message? For example: `var myObject = new MyObject { Id = 909090, Name = "ux909090"}; Serilog.Log.ForContext("MyObject", myObject).Information("Hello World");` We could not find a way to search for the Id without using MyObject.Id =909090. When using a text query like “909090” is it only @Message that is evaluated? Why not @Document as well?

Hi, I'm using Seq v. 4.1.17. I have following query on my dashboard (here, copied and pasted from the dashboard settings): select count(*) as col0 from stream group by name, time(1m) limit 10000 The charts are plotted correctly. There are several groups (having different "name" property). Some of the groups have a value of "col0" equal to zero all the time. However when I setup an alert with condition "col0 = 0", measurement window = 1min, suppression time = 0min, the alert is never triggered. According to documentation: "If the query on the chart is grouped, the condition will be evaluated against each individual group and the alert will trigger if any group matches the condition." The behavior I observed suggest that the condition is applied to the sum of the groups rather to individual ones. Is that a bug? Please advise.

Hi SEQ Team, This morning we had a problem.

surprisingly: The Seq service is installed and running. SEQ.exe process allocated only 20 MB of RAM when normally 21GB. Trying to reach SEQ endpoint then request returned: Error Seq in unavailable. Failed to initialize storage: Cannot access file, the file is locked or in use. The whole problem showed up when no additional workload or maintenance has been performed. The problem has been solved by manual Stop-Process SEQ -Force then SEQ start. Looking forward to a suggestion.

Hi, I have a python project, which uses log and configures it with help of logging.conf file. I want to add seq log as additional handler. When I use sample from documentation I don't see messages in Seq browser. Same seq sample, tested on python test (without config file, without other handlers) works. Please, could you add sample to documentation or explain me what a problem in my code? logging.config.fileConfig('logging.conf') self.logger = logging.getLogger("root") seqlog.log_to_seq( server_url="http://", api_key="", level=logging.INFO, batch_size=1, auto_flush_timeout=10000, # milliseconds override_root_logger=True ) thank you, Igor.
