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

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.

it's not so much if the data is not there, its more the time we need to put into changing the back-end of our monitoring tool to use the files instead of the DB.

Got some news relating to this topic that I'd like to share. 

By now many of us have seen that new installations of Qlik Sense Enterprise no longer includes log db.
Still, having real-time access to warnings and errors is critical for running large Sense environments.

@rva_be-terna pointed out that tools like Butler SOS (butler-sos.ptarmiganlabs.com) pull data from log db - what will happen to them?

I can only speak for Butler SOS, but here is what's currently planned:

First, it will (of course) remain open source. Free to use and contribute to.
It will also keep the same real-time Sense metrics as before (number of users/sessions/apps, what apps are loaded, CPU load, RAM usage etc as today. It will also integrate with the same tools - Prometheus, InfluxDB, Grafana, MQTT etc.

The data pulled from log db will no longer be available, but work is ongoing to pull this data from the log files instead (I outlined this concept in an earlier post in this thread). 
The result is that Butler SOS will get very close to the same (maybe even exactly the same, remains to be seen) log events as today, but from the Sense log files instead. 

That's good, but there is more: 
Because the log db only included data from some log files, this new solution will allow us to tap into log event sources previously not available in log db. 
Hard to know right now how useful that will be - but having flexibility is usually a good thing.

If you are interested in this topic I invite you over to the Butler SOS home over at GitHub, and specifically a discussion about what log events are useful, missing, overrated etc.
Basically a crowd sourced requirement specification for future log events support in Butler SOS.

Cheers,
Göran

When will a new version of the Sense System Performance Analyzer app show up?
I just installed Nov 2021 and it's broken out of the box with no logging DB.

Adding to my previous post earlier in this thread:

Open source tool Butler SOS version 7.0 adds real-time insight into warnings and errors from the log files.

It's not a full replacement for the now deprecated Qlik Sense log db, but it does address some of the features that log db did well.

Butler SOS also adds some new features not present in log db, like browser based real-time view into warning and error messages in the Sense log files.

This page explains the concept: https://butler-sos.ptarmiganlabs.com/docs/examples/qliksense_monitoring_grafana8/#warnings--errors

Butler SOS basically gets events whenever there is a warning, error or fatal message in the log files. These events are stored in a time-series database, after which they can be visualised in tools like Grafana - creating dashboards and takes such as the ones at the link above.

This particular table shows that very detailed information is available in Grafana. Previously you would have to dig through log files to get this info, now it's available in your web browser - you can even create various kinds of alerts based on these events!
