Nagios Core 4.5.9 on CentOS 10

We use Nagios Core on CentOS  for server monitoring purposes, including ping response and other health checks. We monitor whether the server's health is fine or not.

Nagios Core on CentOS  operates with three states: normal, alert, and critical. We ensure that servers are running fine and that services such as ping response and databases are functioning properly. We monitor these through Nagios Core on CentOS.

When any server or application goes down, we receive an alert on Nagios Core on CentOS. This is the main benefit of using Nagios Core on CentOS.

Best feature of Nagios Core on CentOS is that it provides us with reluctant monitoring for our day-to-day tasks. If any server goes down, we receive an alert within a minute rather than waiting for longer periods. Additionally, if we want to receive alerts on our registered mail ID, Nagios Core on CentOS provides this feature. The main benefit is that Nagios Core on CentOS provides us with active passive monitoring.

Active passive monitoring is the most reliable approach in a 24/7 environment where services are critical. We ensure that our services are running fine without downtime. If any person is not available on the system, we receive a mail alert on our registered mail ID through Nagios Core on CentOS.

Features-wise, active passive monitoring is possible on Nagios Core on CentOS. With three states available, we can determine how much attention is needed for each application or service. If it is in the critical state, we must take action immediately. If it is in alert mode, we monitor those services and take troubleshooting steps.

If any service goes down, it enters a critical state and we must take action on an immediate basis. If it is in alert mode, we monitor the situation and take troubleshooting steps on particular services so that without downtime, we cure that service at a particular time. This is the main benefit of Nagios Core on CentOS.

To improve any services on Nagios Core on CentOS, we must make entries in its configuration file. For example, if we want to check any server's ping response on a regular basis, we make an entry in its configuration file and monitor the health service of that server or services. This is how we improve the service of any CentOS  server.

If I want to add any specific improvement, it would be to add automation through Nagios Core on CentOS. If a microservice goes down, I would want Nagios Core on CentOS to take action without human intervention.

The main benefit of Nagios Core on CentOS is that it provides us with active passive monitoring and generates alerts within minutes if any server goes down. It allows day-to-day monitoring tasks to be executed with less human intervention by sending alerts to registered mail IDs. The feature of active passive monitoring is particularly reliable in a 24/7 environment where critical services are continuously monitored without downtime.

With Nagios Core on CentOS, we can categorize server states into three conditions: normal, alert, and critical, helping us attend to services in a structured manner. If a service falls into a critical state, action can be promptly taken; whereas in an alert state, the situation can be monitored closely with plans for troubleshooting. This structured approach greatly benefits organizational stability and efficiency.

Nagios Core on CentOS requires human intervention for monitoring. We take 24/7 monitoring on Nagios Core on CentOS, which is a drawback. We must monitor the services in a 24/7 environment, and I believe this needs to be improved. Additionally, other monitoring tools are available. Tools such as Grafana  allow us to monitor and get logs of any servers, which is something I would like to see added to Nagios Core on CentOS.

Regarding Nagios Core on CentOS's AI capabilities, I believe we can use it for governance and security purposes because it provides an on-the-spot alert if any services are going to be out. This is the main benefit because if any critical services are running, every second matters. I believe Nagios Core on CentOS can be used for governance and security.

The automation part needs to be improved on Nagios Core on CentOS. If any microservice or small issues happen in our organization and Nagios Core on CentOS has the authority, I want to ensure that Nagios has the authority to troubleshoot that issue. Using ChatGPT as an example, it provides alternate solutions that we can choose from. I want to add this feature to Nagios Core on CentOS so that if any fresher is working with it, they can check which service needs attention. This would be a valuable addition to Nagios Core on CentOS.

Apart from monitoring, I would add a log monitoring part in Nagios Core on CentOS.

I have approximately six years of experience overall. I have been working with Nagios Core on CentOS for approximately four years.

I believe Nagios Core on CentOS is stable because it is a stable version, which I think is good.

Scalability is an issue with Nagios Core on CentOS. Nagios Core on CentOS does not provide scalability, and we need human intervention for it. For example, if we need a server that is more reliable during high peak times, Nagios Core on CentOS cannot scale that server without human intervention. This is the automation part which I want to add to Nagios Core on CentOS.

Before Nagios Core on CentOS, we manually monitored everything, which required more human intervention. Through Nagios Core on CentOS, time consumption and other factors have been reduced. This is a good thing for our organization. In a 24/7 environment, it is more beneficial.

Time-saving and money-saving are good parts of implementing Nagios Core on CentOS. Before Nagios Core on CentOS, we manually monitored everything and required more human intervention. Through Nagios Core on CentOS, time consumption and other factors have been reduced. This is a good thing for our organization. In a 24/7 environment, it is more beneficial.

From an organization's point of view, I did not get any opportunity to go through pricing. From my perspective, I don't have any exposure in that area.

Other monitoring tools are available. Tools such as Grafana  allow us to monitor and get logs of any servers.

Nagios Core on CentOS has impacted our organization positively because monitoring is critical. If monitoring is not up to date or if we did not monitor the services of any particular applications, it is a critical oversight. Monitoring is the most important thing in any organization or for any services.

It's good because Nagios Core on CentOS is used for monitoring purposes in most organizations.

I would give good feedback to anyone who is going to deploy Nagios Core on CentOS in their environment because it provides on-the-spot monitoring. I would recommend Nagios Core on CentOS to anyone who wants to deploy it in their environment. I give this review a rating of 7.

My main use case for Nagios Core on CentOS  is monitoring my IT infrastructure, including servers, network devices, and critical services.

A specific example of how I use Nagios Core on CentOS  in my daily operations is checking if a service has stopped or a server becomes unreachable; it automatically sends me an email so I can investigate and resolve the issue quickly. In another scenario, I monitor disk space and system performance on Linux servers and Windows. It is configured to alert me when disk usage exceeds the defined threshold, for example 80% or 90%, or when CPU and memory use remain high for an extended period, which helps me investigate where a problem exists and prevent outages caused by full disks or overloaded systems before they affect users or applications.

Nagios Core on CentOS has positively impacted my organization by moving our time toward a more advanced and modern monitoring solution, resulting in a better dashboard and tools to view system health in one dashboard and also optimizing alert handling.

The best features Nagios Core on CentOS offers are the flexibility to use it for monitoring servers and also using a plugin to check specific services, backup VMs, or other specific checks on my servers, so if there is any error on disk or CPU or high usage of CPU or disk, it helps me have a powerful alerting system and a high level of customization; therefore, the best feature is the flexibility through plugin-based monitoring.

Out of the flexibility, server monitoring, customization, and plugin support, I rely on server monitoring the most in my day-to-day work, and it makes my work easier by providing timely alerts about server status.

One area that could be improved in Nagios Core on CentOS is the user interface.

I have been using Nagios Core on CentOS for approximately ten years.

My advice for others looking into using Nagios Core on CentOS is to start with a very clear monitoring plan before installing anything; define exactly what you need to monitor, servers, network devices, and what metrics truly matter, as this will reduce noise later and keep the system useful.

Regarding Nagios Core on CentOS's security capabilities, it is generally considered solid because it is based on a simple architecture, core, and plugins, which reduce the attack surface; security is managed through standard Linux hardening, firewalls, limited access, SSL for the web UI, securing the web interface, patching, Nginx authentication, and restricting plugin execution permissions, while also keeping systems patched.

Regarding Nagios Core on CentOS's accuracy and reliability of output, it depends on rule-based checks and plugin configuration rather than intelligence, as Nagios Core on CentOS itself does not have native AI capability.

Our main use case for Nagios Core on CentOS  is to monitor our server that holds our services data from clients and patients. We use a FIRE data structure. The data will always send messages to our client based on the condition of the patient. We have about 10,000 patients at that time.

Nagios Core on CentOS  helps us monitor our ecosystem health, our services, and our hosts on the ecosystem. We have visualized visibility on our hosts and services. When the service is degraded or there is an outage, we can fix it as soon as possible. Nagios also automatically tries to fix the data, and Nagios has an outstanding feature in that it can escalate to a manager when there are no actions or no mitigation solved on the incident.

Nagios Core on CentOS sends messages using a WhatsApp API. For urgent matters, it can send directly to the PIC on the server.

Nagios Core on CentOS has positively impacted our organization by increasing recovery between failures. We can keep our services up-to-date.

I don't remember the specific metrics or numbers, but since using Nagios Core on CentOS, there has been a very dramatic increase in our response to the latency on an incident.

The best feature of Nagios Core on CentOS is that it can handle many services using plugins. There are thousands of plugins on Nagios Exchange. At first we were thinking that we had to build the plugin for our needs, but there is a plugin available on Nagios Exchange.

We don't implement all Nagios Core on CentOS features, so I don't think we have a suggestion for the features since we didn't explore all Nagios features yet.

So far, it is enough regarding improvements needed for Nagios Core on CentOS. We don't have any ideas to improve Nagios Core on CentOS, even small ones.

Regarding Nagios Core on CentOS's AI capabilities, there are always updates from Nagios to meet regulations or protect against security attacks. We don't implement that AI capability of Nagios Core on CentOS. It is not fully implemented in our system, so we don't have any comment on that AI.

Nagios Core on CentOS is stable as far as we have experienced.

We can add many hosts and many services to Nagios Core on CentOS, so its scalability is great.

I don't think there will be scalability issues, but maybe in the future, since our organization and our ecosystem will get bigger, we will have to deploy a distributed Nagios, which will be something great to do.

So far, we haven't had any problems using Nagios Core on CentOS, so we haven't contacted customer support yet.

Previously, we didn't have any idea to use a monitoring system for our ecosystem, so we chose Nagios Core on CentOS in the first place.

We purchased Nagios Core on CentOS through the GCP  marketplace.

Unfortunately, we don't have that metric for the cost versus the return on investment with Nagios Core on CentOS.

Regarding my experience with pricing, setup cost, and licensing for Nagios Core on CentOS, it is not my responsibility to justify the pricing. I think it is quite fair.

We went straight to using Nagios Core on CentOS since one of our team members has a lot of experience handling and using Nagios.

I would rate Nagios Core on CentOS 8.5 out of 10 points.

The reason I chose 8.5 out of 10 for Nagios Core on CentOS is subjective. I believe it could be a higher score since we don't explore or implement all Nagios features at this time.

I highly recommend using Nagios Core on CentOS to monitor an ecosystem.

Everything is good regarding Nagios Core on CentOS, and everything runs smoothly as expected.

My main use case for Nagios Core on CentOS  is monitoring all the services of my customers, including CPU, RAM, different kinds of services, and certificates.

The feature to put triggers outside business hours to send a script to block some IPs, some users, or restart any services stands out most to me.

Nagios Core on CentOS has positively impacted my organization by reducing downtime in systems because sometimes there are services that were down, and with a trigger, I can start them again. I can also send an alert to the users or to my companies to try to solve the problem.

I'm not reducing any employees, but I improve the times to solve problems with Nagios Core on CentOS. I also try to improve my tickets to the customer because I discovered things that Nagios tells me to solve. I have increased my company with Nagios Core on CentOS.

Nagios Core on CentOS needs to improve the templates to send messages to IT companies and also integrate with different systems or improve integrations with QNAP, Synology, Ubiquiti, and different applications.

The documentation is good, but the dashboards could improve and be more responsive or modern.

Graphics improvements that are similar to Grafana  are additional improvements that Nagios Core on CentOS needs, but it's adequate for me and it's working well.

I've been working here for approximately eight years. I've been using Nagios Core on CentOS for approximately five or six years in my position.

Since approximately one year ago, Nagios Core on CentOS is improving its reliability and accuracy to get nice precision to the different services and correct monitoring. Nagios Core on CentOS has been operating smoothly and running perfectly, and I have had no bad experiences with it.
