"Nagios is an excellent platform to monitor your network or network services"

What do you like best?

- What I like most about nagios is that it is constantly checking each host on the network and detects any failure that may be occurring, such as high latencies, lost packets or the service dropped in its entirety.

- Another thing that I like about nagios are the alerts that it emits constantly, that way it is not necessary to be entering to check the network constantly, because it gives you an alert in case there is a problem with a host.

- A benefit that I have obtained from nagios, is that it allows you to integrate with other platforms and applications, that makes the work much easier.

What do you dislike?

- Something that would be good to improve, is the fact that the larger the network, the longer it takes to check each host and service, which gives some delay in the alerts it issues.

- The only thing I do not like about nagios is that to implement it requires a certain level of knowledge in the use of free software.

At the company level, it helps you to constantly validate that network services and infrastructure are working correctly, and helps to detect more quickly any damage that may affect other departments.

"Nagios, the only monitor you should use"

What do you like best?

Nagios is very flexible and expandable. We can write our own plugins to custom fit our environment for the exact equipment and checks we need to see.

What do you dislike?

Commercial version is a little expensive, however the "core" opensource version is the same engine and allows us to deploy the plugins we need with alerting we need for our network of over 3k devices and over 9k service checks.

What business problems are you solving with the product? What benefits have you realized?

Pro-active and reactive alerting of critical network equipment. Nagios allows us to keep a closer eye on our SLA customer devices as well.

What Network Monitoring solution do you use?

Thanks for letting us know!

Lo mejor de Nagios es su gran capacidad para monitorizar redes, es una gran herramienta, es de codigo abierto y tiene mucha documentación para su uso. Es muy potente y puedes vigilar tanto hardware como software

Lo peor que tiene Nagios es su gran complejidad, necesitas estar preparado para poder instalar este sistema y poder administrarlo

Si, lo recomendaria a todos los que quieran llevar un control y monitorización de sus sistemas en tiempo real, para asi poder atajar cualquier incidencia de la red lo antes posible.

"Nagios helps us monitor our network with ease"

What do you like best?

Very nice product for quick checks, easy to configure from server and client side, Open source..which can be a double edged sword, but at least you have options. Nagios operates well in large environments. Nagios websit ehas most basics thoroughly documented for reference.

What do you dislike?

All of the false positive alerts are annoying and time consuming to sift through from a technical support/help desk standpoint. It's a reat tool but considering how many years it has been existing it barely evolved. By default every alert triggers a notification. it also does not support plotting graphs of the monitored values.

What business problems are you solving with the product? What benefits have you realized?

Monitoring medium to large scale Wireless Internet network can be a large task, but nagios has helped us manage problems on our network much more efficiently and faster

"Nagios for monitoring"

What do you like best?

We use nagios to monitor our 1000+ server farms and it works great for individual services on each server.

What do you dislike?

I just find that the alert sound is horrible

What business problems are you solving with the product? What benefits have you realized?

The business problems we are solving is ensuring when there is an issue with a server our system admins handle it right away as they are alerted to the issue before it gets out of control. without nagios we wouldn't be able to accomplish that task.

"A Jack of all Trades"

What do you like best?

Malleability is Nagios' true strongpoint. I have seen it used in 3 fairly different environments. I've used 3 different frontends, currently using 2, to interact with the nagios backbone. Each having their own strengths and weaknesses respectively. When it comes to interacting directly with it via the CLI, while not the nicest to look at or work with, it does exactly what you tell it to.

What do you dislike?

Directly editing configurations can sometimes be a bit of a process due to having to dig through the files in the terminal. You get out what you put in, and for most people the quality of their nagios experience will have to do with what front-end they end up putting in.

Recommendations to others considering the product

I have only ever used nagios to monitor systems, would recommend for large scale operations. It is able to handle all of our needs and is highly customizable when it comes to its alerting. I would recommend looking into the various front-ends that are available for it, as that will determine a large chunk of your experience.

What business problems are you solving with the product? What benefits have you realized?

In all the scenarios where I have used nagios, it has been the monitoring of a vast amount of servers/systems and being able to report issues quickly. Without nagios, the online business unit operations teams would be operating "blind".

"Once you get past the hard part, then comes the hard part..."

What do you like best?

Nagios has changed the way we do business in the sense that we are now more aware of our capacity than ever and are able to provide our customers with a next level service that has only improved as we continue to use nagios.

What do you dislike?

Configuring the product can be difficult and outlining information in alerts can also be just as difficult not only for creation, but also review.

Recommendations to others considering the product

Configuration can be difficult, take your time and ensure that you give your whole team a rundown of what you hope to accomplish with the product and their purpose with it.

What business problems are you solving with the product? What benefits have you realized?

A gap in our monitoring solution has now been resolved. There were several fires as a result of the lapse in monitoring that has now been alleviated by the addition of nagios into our systems.

"A basic network monitor that works well"

What do you like best?

The little alert bar that tells you instantly whats going on. As well as the various map types allows you to explore your network looking for links to servers or switches that might have issues, it allows for rapid detection of exactly where your issues lie.

What do you dislike?

A little too basic for most larger organisations

Recommendations to others considering the product

Check out everything, do your own research. This is not for everyone, but good for small to medium sized organisations.

What business problems are you solving with the product? What benefits have you realized?

Mainly server and network monitoring. Has considerably speed up rapid analysis of issues and assisted in prompt resolution of any outstanding problems.

"Still the standard monitoring tool for sys admins"

What do you like best?

Once it's set up, the web interface is great. We use it extensively so that those in dev ops can monitor the server environment. Very flexible and configurable.

What do you dislike?

Can be cumbersome to set up at first. Lots of configuration files. The default templates do help.

Recommendations to others considering the product

Use the templates provided. They go a long way in getting it set up correctly.

What business problems are you solving with the product? What benefits have you realized?

Nagios allows us to monitor servers and notify us when something goes wrong. It gives us more lead time so we can fix issues before customers notice them.

"Excellent Freeware Software for Network Monitoring"

What do you like best?

Overall the price factor but I really like that we can setup services to ping devices all around our office, not just networking equipment.

What do you dislike?

The learning curve is a bit steep but easiest thing to do is build an EC2 instance and dev it from there via terminal

Recommendations to others considering the product

Do your research and don't be afraid to test.

What business problems are you solving with the product? What benefits have you realized?

We've solved a way of monitoring our networking equipment/IT equipment located within all our offices to send us notifications as to when they go down. This is an incredible benefit because we get alerted in real time as to when issues happen.

"Works well, if a little clunky to set up."

What do you like best?

It monitors everything we threw at it. It can even tie into pagers (yes, old style beepers) to deliver notifications. Down time and maintenance notifications are easy to use. The add ons really make this product shine -- with the help of free libraries of addons and plugins online there is very little that can't be monitored by this software. Plus, the price is right!

What do you dislike?

It can be a little clunky to configure -- manually editing text files in a CLI isn't exactly my idea of a great time. There are GUI plugins available, but I have yet to find one that works as well as simply editing the config files.

What business problems are you solving with the product? What benefits have you realized?

This is our backup monitoring solution -- a "who's monitoring the monitor" thing. It works very well.

"Nagios has been reliable so far but always needs tweaking"

I like the reliability. It has never failed us to get alerts.

"Effective but Not Intuitive"

What do you like best?

Nagios is reliable in monitoring network alerts. It also has a huge amount of information that it can use to view the monitoring

What do you dislike?

The UI is terribly awkward and cumbersome. To modify anything you have to learn specific paths that are not intuitive. It is especially difficult to view details on the alerts that are coming in.

What business problems are you solving with the product? What benefits have you realized?

Network object system monitoring.
