Hello Olivier,

I attempted to recreate the issue with latest Ganesha code. It works fine for me.

$ rpm -qa | grep ganesha

Hi Sachin and Wyllys,

I'm running ganesha 3.2 and I'm facing the same stats issue.

Did you find what was going wrong ?

Thanks for your help,

Olivier

I did verify that the client had activity, in fact I was purposely generating activity on the client with the express purpose of generating stats so I could see what it was tracking and generating.  The issue is the "client_all_ops" doesn't recognize *any* of the valid IP addresses (as reported by list_clients) that I've tried to give it (with and without the leading "::ffff:").

I suppose the client has no activity, hence the message.
You can validate it by running below:

#ganesha_stats list_clients
Typical o/p will be as below:

$ ganesha_stats list_clients

If it is 0 for all fields for that client (like ::ffff:127.0.0.1 in above), then client_all_ops will fail.

Im running ganesha 3.2 and I've enabled "all" stats using ganesha_stats but whenever I try to display the stats, it always fails and says that the IP address is not found.  Is this a known issue or am I using it incorrectly?  I've made sure to mount from a v4 client and generate activity on the client.

```
# ganesha_stats client_all_ops ::ffff:10.15.15.2
GANESHA RESPONSE STATUS: Client IP address not found
