Sometimes EDR agents generate more telemetry than anticipated. There's an option to tune telemetry collection via KEA bases, and in order to do it, telemetry profile, aka "topic-dump", is needed in ready-to-use format.
In order to collect telemetry, do the following:
Please do not run apt-sedr-reset before collecting topic dumps.

How to upgrade previously installed password protected KEA using KSC remote installation task.
Step-by-step guide
Edit attached file install_props.json, put there your password for already installed KEA;
Put this file to folder on KSC containing files for creation of remote installation package for new KEA version as per screenshots below;
Create on KSC package for remote installation;
Start remote installation task on KSC.
Most of the time KEA core patches are cumulative and it is sufficient to install the newer one on top of the previous in order to fix new issues.
However, sometimes, for troubleshooting purposes or otherwise, you would need to remove an existing patch. This is how it's done.
Step-by-step guide
In the Administration Console, go to Advanced → Remote installation → Installation packages;
In the right frame, click Create installation package;

As the first step of troubleshooting of KEA, we recommend installing the latest core patch.
However, sometimes such installation will fail. There are two popular causes of this:

This article applies to Endpoint Agent for Linux. To collect LENA debug or ANY traces, please follow this guide.
Default traces location is '/var/log/kaspersky/epagent/'.
Default dumps location is '/tmp/agentdumps'

Kaspersky Endpoint Agent, as many other products, has a few different ways of enabling traces.
Traces folder
NB! The folder specified for traces must exist and be writable. KEA will neither create folder nor display any error if it doesn't exist.
One may choose which is best suitable for their needs:
Traces with restart
In 99% cases, information that is written only during initialization, that is, after KEA restart, is critical for inves
KATA / EDR is using only one certificate for all connections (like WebServer and Client Connections). When you plan to replace it, do it in an early stage of deployment.
If you want to replace the TLS certificate, you will need to:
Reauthorize mail sensors (KSMG, KLMS) on Central Node.
Reconfigure connection of Central Node, PCN and SCN to Sandbox.
Reconfigure Endpoint Agent traffic redirection to Sensor and trusted connection with Endpoint Agent.

Problem
If you install standalone Kaspersky Endpoint Agent, both KSC installation package and local installer provide option to choose, which KEA components to install:
However, when KEA is installed in built-in scenario, bundled with KES or KSWS, you don't get to choose and KEA is installed in default configuration, with all the components.
There's a way to select installed KEA components even for built-in scenarios.

You may need to add a batch of prevention rules to KATA. To speed up the process, we have created a script sample.
Adding more than 1000 prevention rules will require additional PF to improve Web UI performance. Please contact technical support to get this PF.
Adding more than 5000 prevention rules is highly NOT recommended as it may result in drastic performance degradation on both CN and Endpoint Agent.
