JT,

 

While it is possible to increase the amount of requests that can be stored in the mysql db (either the number of requests or the size of the db itself), it's not something that we'd recommend as it can cause performance impact (particularly with the GUI in loading all the requests). If you see more requests being logged than the specified limit, then we'd recommend going with using remote storage.

Hello Ashwin,

 

Thanks for you answer. Based on links that I shared in my question. other "F5 members" have already clarified the fact that it is not recommended to increase theses values.

 

But my question was to decrease it. Indeed, my hope is to change these values for example from 2 GB to 1 GB and from 3 million events to 1.5.

 

Please share the procedure.

 

Regards
