Qlik hostname in log does not match hostname in Cluster

I have just started using Qlik sense as a multi-node setup. We are using AWS EC2 as our server and to go from 1 node to 3 we simply just clone the image of our original server and spin up more EC2 instances of our first Qlik server and that allowed us to quickly setup multiple Qlik instances.

As we can see here in image below:

Everything is appears to be working as expected however, because all the nodes were a clone of the first server so effectively these Qlik server all have the same "computer name" called Unify

However, when I tried to load the Qlik monitoring apps and Log monitoring app I quickly noticed that Qlik logs does not use the hostname that resides within the host.cfg file but instead it is using the computer (server name) as the host

As result when data gets loaded into monitoring app there is no way to differentiate which server the logs came from.

I am wondering if there are ways to change how the Qlik logging service is getting the Hostname so it writes as the AWS Hostname ie. ip-123-456.central-1.compute.internal instead if Unify without renaming the Server and have to deal with out re-issuing certificates and changing a bunch of things.

Any advice would be much appreciated. I just find it very bizarre that the host.cfg file is used everywhere except for the logs 😢

Hello!

Thanks for your question and interesting scenario.

I do not think there is anyway to change how the log file captures the Hostname value however I totally understand your point about using the same value as the one referred in the host.cfg and for that I would suggest you to create an idea improvement here. https://community.qlik.com/t5/Ideas/idb-p/qlik-ideas?_ga=2.51668778.264551744.1614111955-447240192.1559120582

So as far as I know, renaming the server is the only option.

But you should not need to recreate the certificate. My understanding is that currently the host.cfg is using ip-123-456.central-1.compute.internal so your certificates should do the same.

Hope this helps!

Thank you for your response.

Yeah we end up changing the serve rname for all of the rim-nodes and leave the central node alone. It wasn't too painful
