Senior System Administrator at Interactive Group
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.

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

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"The reporting structure and the feature set are valuable to me."
"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."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
"Its an awesome product to use."
"Inspite of this limitation it is a fantastic product to use at zero cost"
"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

"Nagios Core is not easy to use, so I don't recommend it for everyone."
"There is room for improvement in the graphics."
"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."
"Nagios Core does not have a graphic display."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"Nagios Core would benefit from aggregations if a particular server goes down."
"Generally, it does what I need it to do, but better error reporting would be great."
"Third-party connectivity is the part that needs improvement within Oracle Infrastructure Monitoring Cloud Service."
 

Pricing and Cost Advice

"The product is cheaply priced."
"We are using the free version of Nagios Core."
"I would rate the solution's pricing an eight out of ten."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"The enterprise version has technical support. The version we are using is free."
"Lessening the price point would be an improvement."
