Short answer - no. You don't have to if you are sending logs data.
Long descriptive answer. It depends on, if your software is a covered work.
You are building a software that uses an AGPL software by calling its APIs : Your software is a covered work and you need to license it under AGPL and make the source code available to your users. A concrete example would be a monitoring software that calls OpenObserve APIs to provide its core functionality.
You are building a software and use a software licensed under AGPL to monitor your application: Your software is not a covered work and you can license it under any license you want. A concrete example would be - you using OpenObserve to monitor your closed source e-commerce application.
