Nagios [Core]: Best Open Source Monitoring Tool

Rating: 8 out of 10

September 23, 2021

Use Cases and Deployment Scope

Yes, our organization uses Nagios [Core] to monitor all infrastructure and it works finely in a diverse environment. It has very good documentation from implementation to monitoring and web interface, as well as a very good easy-to-navigate icon. The host and service can be organized to manage the host and client easily.

Pros

Network analysis
Effective data collection
Easy implementation

Cons

Web UI should be better while navigating
Improve security
Need to extend support and availability

Likelihood to Recommend

So the Nagios [Core] gave us valuable features like report analysis and graphical structure, so it will easily evaluate and track the issue. Also, the email function is very useful, so we get informed at very crucial times with findings, and also generate templates for popular endpoints which make it very better.

Nagios for the win

Rating: 6 out of 10

Incentivized

May 17, 2021

Use Cases and Deployment Scope

We use Nagios as our alternative Network Monitoring Software for our data centers and out branches. It helps you monitor branch with down wan links so that you can escalate it to [your] internet provider. Also gives you historical reports per device that helps you evaluate and track ups and down of servers or network equipment.

Pros

Network Monitoring
Reports generation
Freeware

Cons

Develop interface to look professional
Gives more detailed report
Add monitors and sensors compatibility

Likelihood to Recommend

For us, we use it just [as] a backup for our main Network Monitoring Systems since it only uses ICMP to monitor the device. If you are looking [for] in monitoring devices using SNMP that will provide you auto discovery and details of your device, Nagios is not for you. But as a backup platform, it is a great tool.

Nagios Core--The best free monitoring solution around!

Rating: 9 out of 10

Incentivized

January 22, 2021

Use Cases and Deployment Scope

We use Nagios Core as our core monitoring solution company-wide. We are alerted if any critical systems go offline or are exceeding thresholds set for disk usage, load average, network performance, etc. This allows our on-call staff to resolve issues before end-users are affected. It also helps us determine budget needs for IT based on age or if there is troublesome hardware.

Pros

Extremely fast alert notifications
Easy-to-use GUI
Not that difficult to configure

Cons

Configuration has to be done on the command line as opposed to a GUI-based config
Plug-ins can be a bit difficult to install at first
False positive alerts can be difficult to track down and fix

Likelihood to Recommend

If you have an organization with more than 10 critical business systems, then Nagios Core is a great, free solution for monitoring. If you're looking to monitor a network or network performance, then Nagios Core is not the best choice; there are other solutions that handle that better. Nagios Core is really good at monitoring hosts and components on a host, such as a MySQL database.

Nagios Core - sit back and monitor at ease!

Rating: 9 out of 10

February 14, 2020

Use Cases and Deployment Scope

Nagios Core is currently being used by our infrastructure teams and enterprise monitoring. We have about 50 users accessing the app, with 3 people serving as admins. The tool is used to monitor hosts and logs, and also dashboarding is one of the favorite pieces of the tool. We have several different apps, and Nagios is a key component to our health!

Pros

Host-level monitoring.
Log monitoring.

Cons

Dashboarding.
Color schemes.

Likelihood to Recommend

Excellent for host-level integration and usability. End users can get right in and use the tool to monitor their environment. Easily able to add tags and groupings, which is a must nowadays. The tool can integrate with LDAP and active directory, but we don't use that. We do everything on-premises and keep users separate.

Industry standard monitoring

Rating: 7 out of 10

December 11, 2019

Use Cases and Deployment Scope

Nagios is our enterprise monitoring solution for all servers and network devices that supporting staff needs to be alerted on. It is used by most of our IT staff, as well as other departments who manage specific applications. It is a very important tool that we use to ensure the services and applications that we host and support are functioning as necessary.

Pros

Monitors a variety of standard metrics.
Uses standard protocols (SNMP).

Cons

Managing monitor plugins could be more centralized and consistent.
Configuration is not very user-friendly.

Likelihood to Recommend

Nagios does standard monitoring of servers and network devices very well. If you have an environment with many basic protocols to monitor, Nagios will work well out of the box for you. It also runs very reliably. Once it is set up, I have not had many problems with the service being available.

Excellent tool that's widely used - and best of all, it's free!

November 7, 2019

Use Cases and Deployment Scope

Nagios is an excellent open-source tool. There is a large community of users who have developed scripts and make them available for other users for just about anything you could ever want to monitor. Nagios is being used to monitor various applications, servers, websites, and services. Once you have set up a few things it is very straight forward to use and configure templates to repeat the task for new devices.

Pros

Monitoring.
Notifications.
Integration.
Strong community of users with shared plugins.

Cons

The native graphing/trending could use updating. It is great for its traditional reporting, but seeing the graphs and trends out of the box would be helpful.

Likelihood to Recommend

Nagios Core is a great tool. It's open-source and free, there is a great community, shared plugins, and many other reasons which make it a great tool. It's very good for small to medium-sized businesses and if you configure it appropriately it could be used for larger organizations as well.

Nagios - Open Source Versatile Infrastructure Alerting Solution

Rating: 8 out of 10

Incentivized

October 22, 2019

Use Cases and Deployment Scope

Nagios is used primarily in the Information Technology department, where it is used for proactive monitoring of server and network infrastructure and associated services.

Pros

Monitoring and Alerting
Service and host metrics
Change management assistance

Cons

End user reports
Metrics
Native support for features (as opposed to plugins)

Likelihood to Recommend

Nagios is well suited to monitoring devices such as network switches, printers, and especially servers, as well as if administrators or end users wish to receive alerts for downtime or other outages so they can be addressed. It is less appropriate for if auditing of services or logging of those services is desired, or if anything beyond up/down or specific application checks are needed in order to monitor a service.

Pros

SNMP Monitoring
Intuitive and simple-to-use interface
Great cost-value balance

Cons

Fault tolerance (redundancy)
