The overall objective to use Nagios Core is "organization doesn't want to pay high monitoring cost" & still wanted to monitor entire data center infra. So, deployed Nagios Core to monitor typical server resource utilization parameters such as CPU, Memory & Disk Utilization.

Later, we configured PNP4Nagios which provides graphical level representation & to see when the WARNING & CRITICAL Level crosses. PNP4Nagios became very useful to get all historical (mostly past 1 year) records when asked.

We primarily use the solution for monitoring ops for computers and our server. We're considering adding other device monitoring as well and at points of sale.

It is used for monitoring services on a bunch of virtual machines.

In terms of the version, we're fairly up to date. We are perhaps not the most up-to-date, but we're fairly current.

We use Nagios for one of our customers to monitor all the servers, firewalls, routers, and cameras. While monitoring the server we get alerts, this enables us to raise a ticket and notify end users that we are aware of the issue before they need to notify us.

We have 80 people using the dashboard and getting the alerts. Depending on the number of servers, routers, and firewalls we are monitoring in current clusters. When one cluster goes down, it will automatically take data from another cluster. 

We support 24/7 because our client is a financial company, if the critical servers go down, they would face financial issues. 

Our primary use case is for monitoring the security of our environment. We have specific services running on our Windows systems and Nagios provides us with notifications regarding the status, whether things are running properly or not. Sites hosted on IIS can also be monitored. We are customers of Nagios and I'm an infrastructure lead. 

We are using Nagios Core mainly for servers. We check the network hardware connectivity. We check for the availability of the network and for hardware failures.

We have deployed Nagios Core on a VM and it's working very well. The specs of the VM are very low because it doesn't require so much storage

We use Nagios Core to detect any issues in our infrastructure, software, system service, and network issues. It is a centralized monitoring service.

We use Nagios to monitor networking infrastructure and services.

I use this solution to monitor my network. There are 25 agents in my country. This solution sends me notifications if any equipment is down.

It's deployed on-premises. I'm currently using version 4.3.3.

There are five people in my company who use this solution.

Our primary use case is for Infrastructure monitoring.

Our primary use case for this solution is an APM for application performance monitoring. For example, we deployed the solution on-premises so we could observe the solution. We look at the threats at the web containers, the data source, and all these components under this monitoring.

I'm primarily using Nagios Core to monitor infrastructure like servers, virtual machines, and telephone usage like IP-DECT antennas. I don't use all of Nagios Core's data functionality. I only use the monitoring features.
