Monitoring solution provides comprehensive visibility across IT infrastructure

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.

Offers real-time alerting and dashboards are great for performance hubs of the database

It's primarily for CPU utilization and resource monitoring. Vulnerability scanning falls under OCI Cloud Guard, so it's related to security concerns. Some people might prefer using a third-party tool for more enhanced features. However, I think Oracle Infrastructure Monitoring Cloud Service could be improved to reduce the need for third-party connectivity. So overall, third-party connectivity is the part that needs improvement within Oracle Infrastructure Monitoring Cloud Service. OCI needs more research and development to understand why clients choose third-party tools like Splunk or QRadar over internal monitoring solutions. There must be some areas where third-party tools are better. OCI could analyze this and improve its service.
