Automation and seamless incident handling transform operational efficiency
I would like AI to be more integrated into Cisco Intersight. It would be great to have a chat session mode AI so that when I am on standby and encountering issues, I could engage with it, much like ChatGPT. For instance, if I need to find commands for UCS Manager, it should provide that information.

The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.
