My main use case for Nagios Core on CentOS is to monitor remote servers and configure alerting. I use default plugins available in NRPE to monitor Linux instances and other running services. I created custom plugins to monitor Docker containers and the processes running inside them, all monitored through Nagios. The way I set up Nagios Core on CentOS is unique because I monitor Docker containers at a granular level. If any processes, such as Python microservices, exit, I receive alerting to Google Chat and email. A separate team works with me to continuously monitor for alerts and inform respective team members to quickly investigate and resolve problems.

I used Nagios Core on CentOS at my previous company, Infosys, for three years. My main use case for Nagios Core on CentOS was monitoring servers. I used Nagios Core on CentOS as a monitoring server to monitor both Linux and Windows environments, and the setup was plugin driven where we configured host and service checks for CPU, memory, disk usage, and critical services such as SSH, HTTP, and database processes.

My main use case for Nagios Core on CentOS is due to the enterprise platforms we run that are based solely on open source; for our R&D division, we need to use CentOS. Wherever we are using CentOS and Ubuntu, we are using Nagios Core on CentOS for monitoring. I monitor all our server devices as a server and storage administrator through Nagios Core on CentOS, especially for server administration; all hardware level monitoring and OS level monitoring will be pushed into Nagios Core on CentOS, where we want to see the CPU memory usage or network usage. In terms of my main use case with Nagios Core on CentOS, when we run any high load or high workload usage, Nagios Core on CentOS will be very helpful because we can check the current load usage of the system, processes running, causing bottlenecks, and network usage.
My main use case for Nagios Core on CentOS is checking disk usage, services, and load of the server. A specific example of how I have used Nagios Core on CentOS in my environment is when I had one server that was a standard server that had been shut down due to server load, and with the help of Nagios Core on CentOS, we checked the basis of the issue, which was helpful. The database services had been down, and we received help from Nagios Core on CentOS in addressing that situation.

Nagios Core on CentOS is used to monitor different services for Windows servers and Linux servers, including monitoring services for MySQL databases and Bugzilla servers, among many others. In a recent scenario, I used Nagios Core on CentOS while working on many web projects, including website development, where I utilized the URL monitoring feature to monitor the response code and verify whether I was receiving a response 200. Using the 200 response code, I monitored different website links to ensure my website was working properly and receiving quick alerts.
