Nagios GUI defaulted back to older version.

You haven't selected the "Unified" views under the "Performance Settings", have you?

Admin > System Config > Performance Settings > Pages tab

If you did, clear these boxes and click on "Update Settings". Did this help?

That is it. That was the problem. I was reading through the Maximizing performance in Nagios XI document the other day and i happen to make these changes. I have nagios running on a physical server but the GUI performance was slower than that of a virtual machine. I was trying to fix one problem in turn created another one. Do you happen to know any tips/changes that i could apply to make my GUI move faster?

[lmiltchev]

Well, it depends on what is really slowing XI. Do you have sufficient resources for the number of nodes that you are monitoring?

You can always add more hardware if needed - RAM, faster disks, etc.

Have you implemented any of the "boosting performance tweaks", described in our Administrator's Guide?

I will look at the document links provided. Mean while here is the lscpu output of my nagios server.

It is a physical server, much bigger than my other traditional 4 CPU x 32 MEMORY VMs i have nagiosxi running on. I usually see the GUI slowing down after i cross 10K services on the server. This one has around 9K services running on it, but give the size of the server it should be pretty smooth.

[lmiltchev]

These are pretty good specs. With 10K+ services however, the I/O may become an issue. I would strongly recommend utilizing ramdisk on the server. Also, you may need to tweak the mysql settings, e.g. increase the max_connections value. See our KB article on the topic here:
