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.

Significant enhancement in operations with powerful discovery and analytics, yet pricing structure poses challenges
ServiceNow IT Operations Management provides out-of-the-box dashboards. Along with the dashboard, it also provides the Operations Workspace, which is very useful for operations teams. There is a functionality called Performance Analytics, which we are also using to develop some dashboards for the senior leadership and operations team where they can perform trend analysis of alerts and events happening across the infrastructure and application landscape. These dashboards are really useful here. ServiceNow IT Operations Management's biggest plus point is that it is a platform. ITOM is just one module that ServiceNow IT Operations Management offers, but they provide seamless integration of ITOM with their other modules such as ITSM, where we can leverage the AIs for discovery, perform impact analysis, which essentially helps to enhance the overall IT operations and reduce the downtime and MTTR.
