Nagios Core

Reliable and comprehensive monitoring for startups and beyond

Commentaires : With Nagios Core we are solving the necessity to keep every single aspect of business critical services we need to guarantee an SLA for. Having notifications and alerts for everything that is happening in your network is a great benefit to keep an edge over competitors. We are very pleased with this free software that delivers despite the difficult implementation.

Avantages :

Nagios is the way to go to actively monitor essentially every single aspect of your tech infrastructure. It is known that having a great response time in case of outages and proactively monitor services before a breakdown occurs is critical to keep customers happy. Nagios Core does exactly that and way more. However, be warned, integration is terribly hard if you want to do advanced configuration. There is a lot of sysadmin/networking/software knowledge that needs to be covered before you get this very special type of monitoring so you may find yourself with small snags that don't let your dream monitoring service come alive but at the end, it is totally doable with Nagios Core.

Inconvénients :

Documentation could be better organized and a few additional GUIs for quick configuration would be a desirable thing. The main interface is very very lean, probably old-style with html4-like visuals and controls but it is effective and light. We basically had an issue with implementing custom plugins to monitor essential aspects of our business, Python scripting was needed but getting this to work effectively on Nagios was another issue. Again, it has a steep learning curve but with time, you can master it.

Nagios is a platform created to monitor network services and member teams of the same.

Commentaires : Nagios is a service mainly used to monitor the components of a network, it gives you the benefit that in case of any failure such as high latencies, packet loss or total loss, nagios issues alerts quickly so that you can solve the problem as soon as.

Avantages :

- The main advantage of nagios is that it allows you to be aware of the status of each host and services belonging to a network. - Another advantage that nagios has is that it has several types of alerts, with which it indicates the type of failure that a host can present and thus be able to solve it as quickly as possible. - Nagios allows you to integrate with other platforms, something that enriches the amount of benefits you can get from this service. - A very good advantage of Nagios is that its code is open, which allows you to make changes and adjustments according to the needs you have in your network.

Inconvénients :

- Something that would be good to improve in nagios is the fact that by increasing the amount of host in the network, the update takes a little longer, causing some delay in the alerts that can be issued. - It would also be good to create a version with the basic functions and easy installation for users with little experience, since to configure nagios requires a certain level of knowledge with free software.

The standard for open source monitoring and alerting that scales with the growth of your environment

Avantages :

-High adoption: Many IT shops are familiar with Nagios Core, lots of discussion and documentation available for the product. If there are questions we have, we can rely on the skillsets of our administrators, and fall-back to online documentation/community support. -Multi-platform endpoint support: Monitoring Windows/Linux servers/workstations is possible, and is leverage in our environment for hundreds of endpoints. -Adding nodes to monitor is simple: Nagios core functionality resides in just a few configuration files. One for monitored endpoints, one for the each of those endpoints' services, and group policies for different profiles of alerting/escalation settings -On-call escalations: We use Nagios Core to notify on-call staff of outages for services for multip teams, via email and SMS messages. Nagios is the foundation of on-call system. -Integrates well with revision control support: configurations are managed within config files, and can be easily managed and control with popular code revision software.

Inconvénients :

-Config file housekeeping: If there are multiple people contributing and managing config files for Nagios, there is a high potential for confusion and messiness within the config files. Training or clear policies regarding organization and contributions to theconfig files is HIGHLY recommended to maintain sanity. Clearly documented practices regarding notification groups for montored endpoints is also HIGHLY recommended to decrease the chances of confusing alerting behaviors for critical systems. Committing files to a revision control software is highly recommended and a watchful eye on the consistency of contributions is key. -Not a slick feature-rich experience out of the box: What you put into it is what you get out of it. Like many open source solutions, commitment and resources from the stakeholders managing this solution will be required in order to get the most from it.

Robust and fully functional with a huge learning curve. To use this you need to invest a lot of time

Commentaires : Monitoring of servers and individual services with easy to use notifications and alerts.

Avantages :

Nagios Core can do literally anything you need it to thanks to the amazing developer community and their ability to program custom addons. Need to monitor servers all over the world? No problem. Need to schedule outages and downtime? No problem. Need to monitor a custom system that only a handful of people use? There is most likely a module for that as well.

Inconvénients :

To make it all work, you need to have advanced knowledge of linux command line administration and the ability to modify configuration files from the command line. Also, a few years of practice won't hurt to learn how to fully utilize Nagios Core.

Nagios is a software created for the constant monitoring of equipment and network services

Commentaires : Nagios is a platform that allows you to effectively monitor all the components or elements of a network. It offers several types of alerts with which you can identify the type of failure that the host or service may be presenting.

Avantages :

Among the advantages offered by nagios, is the fact that you can monitor all the equipment and services you have in a network, in this way you can know the status of each one, something that is very useful to validate that everything is working correctly in network. Another advantage that nagios has is that it gives you several types of alerts, it shows you if a host is missing packages, if it has high latencies or if it is completely down, this is useful because it helps you to better detect the type of failure that may occur . Nagios also offers you the implementation with other platforms, which is useful when you monitor a network and at the same time use other tools to manage it.

Inconvénients :

Something that does not have very in favor nagios is that when the network is very large it takes a long time to update, which generates some delay in the alerts that can emit some host. Another disadvantage that nagios has is that the configuration is somewhat complex, which requires high knowledge in that area.
