APM usage

Hi,

 

We have a viprion machine running 12.1.2 version, which is configured with about 600+ VPNs and ACLs and Network Access split tunnels resources ...

 

We want to do a cleanup to all unused VPNs in the Access policy ..

 

How to find out which VPNs were not used for a lot of time ? Is there any way to do that ?

 

Thanks
