Featured Reviews

Simon KONAN - PeerSpot reviewer
Plug-ins are free but it has limitations in sending out information to users
The issue my company has with the tool stems from the fact that it didn't give an on-time response to us. The product collects the information, but it fails to send them via SMS, WhatsApp or Telegram. The solution can be used if you want to get email notifications, which is not good for our company because if someone is not in front of their desktop, you can't receive information about an equipment or LAN that is down.
Amir  Said - PeerSpot reviewer
Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
Tom Condo - PeerSpot reviewer
If CPU, memory, or disk space is over-utilized, it alerts us immediately via text or email if there is an issue
When it comes to the intuitiveness of the topology mapping feature, our network architect created a vision diagram of our entire network and then created the links tied into the WhatsUp active monitoring to different spots on our topology map. It's one of the more critical functions we do here. We have the map displayed in different places in our room and help desk. We get alerted via emails but we can also see it visually. It does what it says it's going to do. We find this feature very helpful. The interactive mapping interface for scrolling, zooming, and drilling down on an element to learn about a network issue is good. When we see a network there will sometimes be a spot that has one link. You can go into a particular part of the topology map, scroll in, and see exactly which module it is. All the information is provided. This feature really helps. You can see the correlation between that link and what failed. This feature is very helpful. The interface is fairly intuitive. Some of our users used SolarWinds and Nagios, and WhatsUp is easy in comparison. Once you get set up, the look, feel, and configuration are good. Our network architect had never used it before but he was able to create the Visio and map. It was very simple. He has no problems with it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Another feature we use is Business Activity, which provides us with an end-user perspective when a service is down or isn't working correctly. This is helpful when monitoring the KPIs. When we see a device or server that isn't working, we find the root cause."
"We have a single GUI where we can view the status of all our infrastructure."
"The most valuable feature is the ability to build an abstraction of service visualization. You can add services to an entity called Business Activities and you can see the state of these activities."
"It supports active monitoring so we don't have to use traps. From time to time traps are not very useful because we never know if they are actually working or not. The reporting part is also valuable as are the event logs. Using them we can check right away if something has had a hiccup."
"I find the product's scalability to be one of the most valuable features since it allows us to add unlimited devices for monitoring and to set up additional polling servers without additional license cost or downtime in our monitoring."
"Centreon's most valuable feature is Opsgenie."
"For servers and for applications, it was very, very efficient."
"I can't point to one valuable feature. All of Centreon is good."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"This is a very good solution and it is simple to use, for any company."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"The tool's most valuable feature is the visibility it offers of everything in the network and infrastructure."
"The interactive mapping interface for scrolling, zooming, and drilling down on an element to learn about a network issue is good. When we see a network there will sometimes be a spot that has one link. You can go into a particular part of the topology map, scroll in, and see exactly which module it is."
"This is a good, stable network monitoring solution for devices."
"I use it on premises to monitor my network database. We monitor the link up/down and use the SNMP traps as well."
"Our local support team provides excellent service."
"The most valuable feature of WhatsUp Gold is NetFlow and the virtualized maps."
"The threshold alerting is the most valuable feature."
"The most valuable features are network bandwidth monitoring and monitoring device health."
 

Cons

"Currently, we have to go through all of the different templates and take a look at how the template is configured, and how specific parameters may change across different templates with different precedents, megatons, etc. It's a lot of work and involves trial and error. I wish they could simplify the process."
"It is necessary to improve service monitoring of database services in the free version."
"I think Centreon's security could be improved by leveraging AI. That's where things are heading in the industry."
"Improvements I would like to see include a discovery solution, better reports, and end-to-end monitoring."
"Centreon needs to improve the granularity of the data as well as the graphical data. It would also be better to if there was improvement to the filtering/grouping system as well as the creation of views."
"The reporting has room for improvement."
"Centreon is actually missing an easy way to create a trendline for the metrics. Actually it is possible to create it, but you need a good knowledge of math, Centreon, and RRD."
"I would like to see an improvement of the communication with big data systems, because Centreon is a monitoring system. In our point of view, Centreon should be a part of a source for a big data system, not a big data system itself. So, it should be easier to add data from the Centreon system to a big data system. For example, it should be able to teach machine learning."
"I would like to see support for notification via SMS."
"The product's stability could be even better."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The GUI could be improved."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"We'd like to see more integration capabilities."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"The point system is not clear and clarity around this would improve our understanding of the system."
"You have to invest a few days to become an expert in this solution."
"The tool should focus on increasing its market share, as it is the only area of concern where improvements are needed."
"One of the biggest things that made us start to look at another product is we're not able to have an end to end monitoring from a user perspective throughout the system and back to the user. All the monitoring is from inside out, we need something that also can give us from outside in."
"I would like to see them do an enhancement to the application monitoring. A lot of other products do better application monitoring so they should do some improvements to the application monitoring."
"Improvements are needed in integration, especially for WhatsApp call and messages. Our region heavily uses WhatsApp Messenger for communication, and integration with this platform would be beneficial."
"The technical support does not bother to respond."
"The interface needs some work."
 

Pricing and Cost Advice

"I think Centreon's pricing is fair, especially given the criticality of our system. They were cheaper than the other solutions. The licensing terms were pretty straightforward. I believe it was based on the number of hosts."
"If you need basic monitoring without dashboards, just monitoring, the plugins are very useful and really cheap. If you want a more complete solution with dashboards and reporting, the EMS solution is great and it is not that much more expensive. It's a good value. Really good."
"The pricing works out well for us, given our environment and where we are."
"You purchase a package. You have a support contract (there is also a platinum support contract) and it is per module. That means you have to pay, e.g., for the MBI module or the BAM module. Or, if you want to save a lot of money, you can pay for IMP, which is the complete package."
"Centreon is better than Nagios XI in regards to cost and support response times, when you have a problem. If you have a problem, it costs money to contact the Nagios XI support."
"The pricing starts at around 5000 euro. However, this depends on: Your environment, the size of your host, how many hosts you have, how many remote pollers you have, and if you want to use the Monitoring Business Intelligence or Centreon MAP functionalities."
"Centreon is always available to develop new plugins when needed. The most important thing is that their maintenance account yearly subscription fee includes the fact that they will maintain the new plugins that you requested them to deliver."
"It is perfect and very cheap if you are a little company or startup. After that, it is quite expensive for a big company."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is an expensive solution."
"As it is not an agentless tool, I think it is expensive."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Nagios XI is open source."
"The pricing is high with separate licensing for the product and support."
"The most valuable feature is the cost compared to other solutions."
"It is per device, per year. The pricing is very clear. If you have a service agreement, you get all of your major upgrades and minor upgrades. It was under $10,000 to go all-in with all of the different add-ons for it."
"This is a well priced solution."
"The pricing can be on the expensive side when considering competing products."
"The tool's price is reasonable. WhatsUp Gold is cheaper than SolarWinds."
"There are some subscription charges that are quite heavy. I need to pay for support every year and these charges can be quite expensive. Aside from the initial cost for the tool, you need to pay additionally for support."
"The choice of version depends on the number of points, or devices, that you want to monitor, and this makes the product expensive."
"There is a license needed to use WhatsUp Gold."
