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.

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 application performance monitoring feature is valuable."

"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."

"Dashboard provides monitor of total assets."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"We mostly use Nagios Core to integrate with Python and Bash Script."

"The reporting structure and the feature set are valuable to me."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

More Nagios Core pros

"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

"The core version is no match for the XI version."

"The interface could be improved."

"I believe Nagios Core will need to provide an option for big data platforms in the future."

"It is a bit slow due to latency."

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

"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."
