Command diag debug app ike -1 not working in 5.2.4?

Hi all,

I'm trying to remotely troubleshoot some VPN issues on a 140D running 5.2.4

In the past (on older firmware, on another device...) I've used the command 'diagnose debug application ike -1' and it will return very verbose information on what the VPN tunnels are doing or trying to do.

I have made sure to run diag debug enable also

However, running the command on this other device returns nothing. If i bring the interface down/up I get the following only

2016-06-10 06:14:42 ike config change 2016-06-10 06:14:44 ike 0:VPNxxx01: is admin up 2016-06-10 06:14:48 ike config update start 2016-06-10 06:14:48 ike config update done 2016-06-10 06:14:49 ike 0: cache rebuild done

Am I missing something, or using the wrong command? Or, do I need to enable logging somewhere else on the device before I can see all the information that I'm used to seeing when running this command?

Thanks!
