They don’t have logging running because of the massive data load. But the LB guy sent me the attached screenshot saying that it shows that all three nodes get an equal amount of requests.
If they really do, the I wonder why on one of the nodes I only see 2, 3 users and and on the others an equal amount. Those 3 users are BTW AR Admin and two technical users. Wired. Also speaking of amount of users I check the license usage. Not aware of any other way checking.
