Nagios XI Reviews

Nagios is an open source monitoring tool for monitoring network services. Installation is quite easy and the interface is user-friendly and configurable. We can monitor disk space, CPU utilization, memory usage, host availability, NFS availability and a lot of other things. Due to its extensive features, it is widely used in IT markets.

We used to get the system hung. After monitoring implementation, we keep on getting alerts for CPU, memory and other things. So, we take care of servers now before it goes to hung state.

Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end. So far, clustering and failover of Nagios is not available-- development is still working on it.Highly recommended tool for monitoring services.!!

I have been using Nagios for 4 years now and still using it.

There were no issues faced during deployment. It was pretty handy and most of its docs are generally available over the internet.

Alternatives Vendors: Zabbix, Opennms, Zenoos, Cacti !!

Nagios is our cloud-based monitoring system. We need to deploy it and integrate with our CRM, customer portal and the ticketing system as an end to end customer support platform. We use it for monitoring and gathering data from our customer service equipment.

We have more than 100 people using the solution and 3 people to do the maintenance.

Nagios XI has a custom API feature, and we can expose custom APIs for our integration. This is a great feature.

In fact, Nagios XI grant access to administrator to use official common backend commands and callback functions developed by Nagios in custom APIs, so custom APIs could be created as an standard web services without degradation in performance and access to needed data easily. This APIs will be registered and listed in Component Management and administrator could be able to manage them as well. Also, Authentication will be done by creating unique Token for each user created in Nagios XI User Management automatically and it could be used in calling each APIs to manage access level of caller user.

All documentation and examples about creating custom APIs are available in "Help" tab in monitoring GUI and each person with moderate level of knowledge about development in PHP language  (Needless to say it required admin privilege), can create this kind of web services. 

We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios. Some products such as Zabbix have a software monitoring system built-in, such as the Prometheus monitoring system. It can use the features to monitor cloud systems. This would be a useful feature to include in Nagios XI. Nagios has some plugins to monitor clouding systems, but this feature on Zabbix is so handy and so user-friendly. I think it can be added to the Nagios monitoring system.

Nagios is stable, but we are using mod-Gearman for distributing the solution. There is network limitation on this, such that if the network is not stable, the whole solution is also, not stable.

Because we are working in Iran, we have embargoes, and this means we don't have any support from Nagios support. As a result, we have to use self-study. We research using Google and nagios forum this has helped us to resolve our issues.

Set up in Nagios is complex. However, it's okay once you have done this task a few times, so you understand the logic. Once you have done that, it is easy to use.

We also compared the product to Zabbix.

I would recommend this solution because it's so powerful with no limitation, especially when using the XI version. I would rate Nagios 8 out of 10. Overall, I find it to be a very good solution.

• The integration with the alerting software 
• Automated maintenance windows 
• The ability to set up templates and groups of checks, as well as customize the checks themselves.

We receive alerts for services and servers experiencing problems throughout the day and night, so we can maintain 24/7 monitoring.

Improve the documentation, examples, and best practices, therefore users can understand how to do things. Luckily, I had someone teach me the ropes, but to newcomers without someone to train them, it would be very difficult to learn.

Around two years.

Generally, it is very stable platform. Occasionally, we have to restart the monitoring engine, but it is very easy to do.

Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process. Since documentation is lacking, it's a matter of trial and error before things work properly. So yes, scalability could be improved.

We did not purchase support, therefore building the entire platform in-house. This has probably led to us not using best practices.

It's generally good, but lacks documentation.

We must separate the 2 parts of this product :

Monitoring Core (Nagios Core) -

Possibilities to manage Nagios Core and Nagios Client configurations by Service Manager like Ansible, Puppet etc. For big environment's, it's the simplest way for industrialisation

• Correct and scalable Dashboards for management
• Easy way to view you entire production ( more complete than Nagios Core interface)

My customer choose this product because he previously worked with Nagios Core 3 and didn't know other tools. His principal argument for him is that the Dashboards correctly present their work.

The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work. You must choose a way to manage your configuration, by interface or by files in Core, and never change your rules. If you choose files, you lose the dashboard advantage instead of importing them manually, and, for the moment, there are no APIs for managing hosts/services are present. If you choose Interface, you must configure hosts/services manually, and again there are no APIs for managing hosts/services are present.

Nagios Core has a big advantage in that has been lost in Nagios XI. Another way you could manage is by having three different databases

1. Postgres for Nagios XI's hosts/services définitions
2. MySQL with ndo2db for metrology
3. Rrd for the Nagios Core

This is not easy to maintain and High Availability becomes complex. The simplest way is by VMware HA modifications preconfigured by Nagios.

I've been using it for the last six months.

It's very easy to install it and manage it with Nagios XI's interface.

There have been no issues with the stability.

I only have 50 hosts and haven't needed to scale beyond that.

Nagios responds quickly when you need them, and the community is really big.

I previously used HP SiteScope, Nagios Core 3, Xymon and Zabbix. I didn't choose Nagios, my customer choose it and I implemented it. My prefered tools is Zabbix for the moment.

It's very easy for the basics features, but, like others tools, when you need plugins, it becomes more complex.

We did it in-house.

No ROI was requested by my customer, only visibility by their management and using their knowledge on Core 3.

Your architecture must be conceived prior to implementation as each error must become complex to change.

• Alerting with SMS and e-mail
• Monitoring services on hardware status

It improves the time to resolve incidents and administration of the system.

Improve the time to resolve incidents.

Improve the KPIs for availability.

I have been using it since 2010.

There are stability issues if you have a large number of hosts and services.

There are scalability issues if you have a large number of hosts and services.

Customer service is good.

Technical support is the best.

We did not previously use a different solution.

Initial setup is complex.

I'm an expert for this solution.

The ROI is very good.

I'm using the open source version.

Before choosing this product, I did not evaluate other options.

It's the best solution for enterprise PME.

Nagios XI is used to monitor servers, services, and applications, as well as the network.

Nagios may be used to monitor anything having an IP address. Also, we can customize it to the requirements of the customer.

The most useful aspect of this solution is the ability to customize it for the client agent.

Technical support is an area that needs improvement. It is not available 24/7.

Having some additional features added would be beneficial.

I have been using Nagios XI for five years.

I am working with the latest version.

Nagios XI is a stable solution.

The support is good. I would rate them a seven out of ten.

Neutral

The deployment is determined by the customer. We have a large number of clients. Some clients host it in the cloud, while others host it on-premise.

Some clients have Amazon, and some clients have Linux.

The initial setup is easy.

The software installation does not take much time, half an hour. The onboarding of it will depend upon the environment.

We are partners with Nagios XI.

I would rate Nagios XI an eight out of ten.

Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want.

Since my organization has many companies in the form of customers for handling their infrastructure and application, we used to use the paid tool before. However, the open source technology is the best thing for an organization in today's world. When it comes to monitoring Nagios, it is the first choice in open source tools. We started using the Nagios XI for monitoring and it also has a feature for handling events, which we can use to integrate for creating tickets with any ticketing tool using its API.

Nagios XI can improve its GUI for users with a new look. Otherwise, we could develop it on our own. This is the reason I think most users don't prefer it, but technically it is a very strong tool.

Four years.

No. Its new releases come from time to time. Also, if you don't have much expertise, you can opt for its support, but it's a paid service.

An eight out of 10, because technical support always has room for improvement.

Yes, we used a paid monitoring tool and used to pay a lot of money. Nagios saves a lot of money for the company.

Nagios is straightforward and simple. It has very good documentation as well as a very active forum, too.

If you can build a Nagios with add-ons, you can use Nagios without any pricing and licensing. Also Nagios XI does not charge much as compared to other monitoring tools. It is best in terms of pricing, too. I would suggest that if you have expertise, you should go for Nagios and build a Nagios XI type monitoring system without any license or pricing.

Nope, but I know the other monitoring tools which are paid as well as the open source. I like Nagios in comparison to them.

Enjoy Nagios. No need of advice. This is very good product. Just use it and experience it.

Nagios is the best monitoring tool that I have ever worked on. You will never like it if you compare it with other paid tools based on the graphical interface or any other features. Nagios is the best open source tool. We can create a plugin by ourselves and actually monitor whatever we want.

Nagios XI is a Nagios, which is flavored with some features and we have to pay for it. If we use Nagios, we can build ourselves the Nagios XI feature on our own using the add-ons.
