Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

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

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

"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."

"The application performance monitoring feature is valuable."

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

"The good thing about Nagios Core is it covers everything."

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

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."

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

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

"The mapping is a little hard."

"Would benefit from aggregations if a particular server goes down."

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

"I would like to see more training videos."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"Nagios Core can improve the graphical interface, it would make things a little easier."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

More Nagios Core cons

"Third-party connectivity is the part that needs improvement within Oracle Infrastructure Monitoring Cloud Service."

Pricing and Cost Advice

"We are using the open-source, unpaid version."

"Most the plugin features are free."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"We are using the free version."

"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."

"The solution is expensive."

"Lessening the price point would be an improvement."

More Nagios Core pricing and cost advice

"For monitoring specifically, it's not that expensive. The licensing is yearly basis."
