Room For Improvement

Cisco Intersight needs improved migration, integration, usability, automation, and cost-effectiveness, with emphasis on stability and on-premise features.
Nagios Core needs a modernized interface, simplified configuration, scalability, and integration with tools like Grafana for improved usability.
For how Cisco Intersight can be improved, I focus on two points: visual policies, which I believe is the most important improvement, and the possibility to work with local labs in a local infrastructure.
Consultant at SOSNET
There is a significant issue regarding migration from UCS Manager into Intersight without formatting the Fabric Interconnects (FI), which is problematic in a production environment.
System Presale at Bezeq
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.
Systems Engineer at FNB South Africa
 

Setup Cost

Cisco Intersight offers competitive pricing with free and paid tiers, offset by high initial costs and complex pricing structures.
Nagios Core provides cost-effective, open-source monitoring with engineering setup and maintenance, requiring customization expertise for full benefits.
The biggest consideration is ensuring that the additional functionality and time saving justify the ongoing licensing expenses.
Software Developer
The pricing is fair and reasonable, particularly for enterprises.
Systems Engineer at FNB South Africa
Cisco Intersight's license cost is very high compared to AWS and Azure solutions, which have lower initiation costs.

Valuable Features

Cisco Intersight enhances data center management through automation, integration, predictive analysis, and AI-driven insights, reducing manual work.

This solution has provided time savings and required fewer people to operate this tool, rather than direct cost savings.

Centralized monitoring has improved visibility and standardizes profiles across multiple sites
One area where Cisco Intersight could be improved is making the interface and troubleshooting workflows more intuitive, especially for users who do not work with the platform every day. Sometimes finding the exact information needed or understanding certain alerts can require navigating to multiple locations. I would also appreciate more actionable recommendations alongside alerts rather than just identifying an issue and leaving the next step entirely to me. Overall, the functionality is strong, but improving usability and making troubleshooting more straightforward would enhance the everyday experience. Apart from usability, Cisco Intersight could benefit from smoother integration with third-party monitoring and IT management tools. Having alerts, performance data, and infrastructure information flow more seamlessly between platforms would reduce the need to switch between different systems. Performance-wise, keeping dashboards responsive when managing larger environments would also be important. I would also like to see more practical documentation, particularly step-by-step troubleshooting guides and real-world examples for automation workflows. These improvements would make the platform more accessible and efficient for everyday operations for new and existing users. Smoother integration with third-party monitoring and IT management tools would allow alerts, performance data, and infrastructure information to flow more seamlessly between platforms. These improvements, including usability enhancements, would make the platform more accessible and efficient for new and existing users.

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.
