Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"Nagios XI is a simple monitoring tool with performance management."
"Nagios XI helped me to draw the network and check for system failures."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"An excellent solution that is easy and intuitive to implement."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"The solution has a lot of plugins and scripts integrated with it."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"Real-time alerting is a very important feature. We need alerts for everything. We have alarms setup and get alerts through email or third-party integrations depending on what's happening – critical VMs, high CPU usage, security concerns."
 

Cons

"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The tool's AI model needs to be fixed."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"Third-party connectivity is the part that needs improvement within Oracle Infrastructure Monitoring Cloud Service."
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"We are using the free version of this solution."
"Nagios XI is open source."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is an expensive solution."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"For monitoring specifically, it's not that expensive. The licensing is yearly basis."
