Hi all, After modifying Trend Micro Vision One integration (setting 'preserve\_original\_event') and restarting the agent, what can I do to make the change effective? Thanks a lot! ---

When you deactivate the option and apply the change it is supposed to be effective immediately, after the change the field called “event.original” which contains a copy of the original log will no longer arrive. If for some reason the change does not take effect, I recommend you to check the agent logs regarding the integration to determine if there are errors or if it is in an unhealthy state. ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/b/9b3d956007148eb9a29030b12a47c45c59113b51.png)
