Deprecation of Centralized Logging in Qlik Sense Enterprise on Windows

[Jamie_Gregory]

Hello Qlik Users!

We would like to announce the deprecation of the Centralized Logging service in Qlik Sense Enterprise on Windows by the end of 2021.  

We will remove the Centralized Logging service to make Qlik Sense Enterprise on Windows more reliable and performant.

Logging will continue to be available in file format. We are updating the monitoring applications to support this change and provide you with the same insights.  

With Qlik Sense Enterprise May 2021 and on, a fresh installation of Qlik Sense Enterprise on Windows will not deploy Centralized Logging.  

We will provide a firm date for the removal of the service later this year.

As always, feel free to contact us if you have any questions.

Thank you for choosing Qlik! 

Kind regards,

Qlik Global Support

Once this occurs and the DB is not used, how will this affect the license and performance monitors?

@Thomas_Hopp @Bastien_Laugiero Can either of you help @Cat_db01 and @twales?

[Bastien_Laugiero]

Hello,

@Cat_db01 if you switch it off now, the only potential impact is that the monitoring app called "Sense System Performance Analyzer" will stop reloading as it load its data from Qlogs. The other monitoring apps supports loading data from the logs files. 

@twales The license monitor supports both Qlogs and log files, so there shouldn't be any impact there. As mentioned above only the  "Sense System Performance Analyzer" only supports Qlogs and our R&D team is currently working on it. 

Hope this helps!

So we currently have the Qlik Logging service running though we haven't enabled it during the install. When we upgrade QS to the version May2021, will the installer remove the logging service as part of the upgrade?

Hey there @ansarikashif2017 ,

no, the upgrade to QS May 2021 will keep the service (since the postgres version is not upgraded, when you upgrade QS to May 2021... and so, Centralized Logging is still available)
Side note: we don't install Centralized Logging as well, and usually we set the Qlik Logging Service to Manual start. This way is clearer that the Centralized Logging is not used

I hope this helps,
Riccardo

Hi,

Our custom made web-tool relies heavily on the data coming from centralized logging to keep an eye on performance/issues. Will the logs provide the same exact same data structures as the views did in centralized logging?

Is there also an way to receive these messages via mail, I only stumbled on this article by chance so it's going to be a nightmare to refactor everything before the end of the year.  found it, had to manually subscribe..

Thanks.

Believe you can subscribe to groups here in the forums and get all posts as
email.
On mobile now so cannot check exact process for doing this, but at least I
have that sub setup. Works fine.

Whether the log files contains all info that today goes into the db, I am
not sure.
Having worked lots on the logs, processing them with various tools, I've
however yet to find a single use case that could NOT be solved by data in
the log files.
So I'd say your odds are pretty good if you just dive into the logs and
pull the data you need from there.

I'd say you won't have one stop shop for Sense and machine metrics out of the box as in Sense System Performance Analyzer app which loads "platform events" from the Logging DB. I'm pretty sure there's a way to load that data into Sense, but we'll need to do a bit of hacking.

That being said, I must say that Sense System Performance Analyzer did help me on several occations to show/prove that it is not Qlik eating all the memory on a certain server.
