Automation has transformed endpoint deployment and streamlines multi-vendor network operations
The best features that Cisco Crosswork Network Insights offers include a single pane of glass, multi-vendor comparison, and the ability to reduce engineer workload. The single pane of glass and multi-vendor comparison features help my team day-to-day because with the single pane of glass, we are able to manage everything at a single place, hence saving a lot of time, and the administration becomes very easy. Additionally, there is real-time network monitoring and analytics, multi-vendor and multi-domain support, scalable AI-driven insights to make data-driven decisions easy, and a modular application ecosystem with open APIs. Cisco Crosswork Network Insights has empowered our team to deploy network devices at customer locations more efficiently than ever before, and it also delivers critical network telemetry, streamlining troubleshooting and reducing reliance on manual processes. Cisco Crosswork Network Insights has positively impacted my organization by enhancing automation for endpoint deployment, hence saving a lot of time, and network usage statistics delivery to the end user's environment has been quicker.

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.

Pros

"Cisco Crosswork Network Insights has been very fundamental and robust and helpful in my organization, empowering our team to deploy network devices at customer locations more efficiently than ever, and it also delivers critical network telemetry, streamlining troubleshooting and reducing reliance on manual processes."
"Cisco Crosswork Network Insights has positively impacted my organization primarily through security and trust, as it provides monitoring of routing health, IP health, and protection from hijacks or leaks."
"Cisco Crosswork Network Insights has positively impacted us by securing our data, including customer data, and it secures our cybersecurity products while being excellent for security purposes."
"Cisco Crosswork Network Insights has impacted my organization positively as it has saved a lot of time, reduced management overhead, and simplified operations through a single pane of glass."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."
"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"The solution is quite efficient."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
 

Cons

"There are aspects of Cisco Crosswork Network Insights that I feel need improvement, such as faster data processing, as it currently takes too much time."
"Cisco Crosswork Network Insights is not an easy-to-use product and thus requires some training to ensure that it can be used to the best of its capabilities."
"I have not seen a return on investment yet; we are still working on it."
"My experience with pricing, setup cost, and licensing is that it is somewhat high compared to other network products similar to Cisco."
"Nagios' great customizability is also one of its greatest drawback."
"It is a bit slow due to latency."
"The scalability needs improvement, it's not scalable at this time."
"t was a little hard to get our setup represented in the configuration."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The user interface could be more interactive because it is pretty basic."
