Assistant Manager at Lauren Information Technologies Pvt Ltd
Has the capability to automatically integrate with a large number of products
Scalability-wise, I rate the solution an eight out of ten. I have not worked much on other technologies, like SAP or VMware's virtualization part, on-prem infrastructure, or cloud infrastructure. Instana Infrastructure Monitoring is so fast and easy to adapt that it works fine. I have not explored other operating systems or infrastructure solutions because my company doesn't have that customer scale. Most of our customers are on-prem or on AWS or Azure, but Instana Infrastructure Monitoring adapts to their infrastructure very well. My company came to know how well Instana Infrastructure Monitoring adapts to our customers' infrastructures when we take care of the PoC phase. Around 12 to 15 people in my company use the product.

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.
