A stable, scalable, and flexible monitoring tool
Real-time data is one of the unique features that ITRS Geneos offers. For example, if there is an impact on a particular server and a particular application, I want to see what the impact is or what the CPU or hardware usage information is, as well as the service in the same application. I can see the real-time data and the impact by accessing ITRS Geneos and looking at the tree. I don't want a tool that tells me when something is broken. I want the tool to tell me when something is going to break. That is the difference between ITRS Geneos and other tools. I want proactive monitoring, not reactive. I don't need to be notified after the fact that something has broken. If something is broken, I get a notification by email, and some of my customers are going to call me. ITRS Geneos provides proactive monitoring. The great advantage of this tool is real-time monitoring. ITRS Geneos not only alerts us but also gives us a real-time view of the data. This is the tool's first great advantage. It is also lightweight and flexible and can adapt to monitor even low-latency systems, which is the tool's second advantage. Another great feature of this tool is its good presentation layer, which allows us to build custom dashboards to present to business stakeholders. This gives them a high-level status of what is being monitored. If we compare ITRS Geneos to other tools, we will find that each one specializes in a specific area, but the ITRS Geneos tool is more comprehensive. This is its great advantage.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

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

Pros

"One of the most valuable features is that it can be configured by non-developers. It doesn't require development expertise to configure it."
"The solution is used across the entire investment banking division, covering environments such as electronic trading, algo-trading, fixed income, FX, etc. It monitors that environment and enables a bank to significantly reduce down time. Although hard to measure, since implementation, we have probably seen some increased stability because of it and we have definitely seen teams a lot more aware of their environment. Consequently, we can be more proactive in challenging and improving previously undetected weaknesses."
"Real-time log monitoring with desktop alerts is valuable as it tells us immediately when there is an issue."
"The NetProbe carries over 100 samplers which are capable of monitoring hardware, OS, and the application layer."
"I always appreciate Geneos's stability and ease of use."
"Custom script toolkits"
"The solution's log monitoring and alerting mechanisms are very user-friendly and easy to plug and play."
"The clean and colorful UI and easy to use options like snooze and active times."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"It is an open-source platform with valuable features for performance and stability."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"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."
 

Cons

"t needs to have better middleware integration for things such as application and Microsft SQL servers."
"The dashboard feature is full of bugs. Grouping items results in a distorted dashboard."
"Geneos' application monitoring could be improved a lot. Products like AppDynamics and Dynatrace provide the process thread-level monitoring, but Geneos lacks these capabilities."
"Sometimes, if there is a lot of data coming onto the servers, we have observed a little bit of slowness on the gateway servers which are doing the ITRS dashboard monitoring."
"I would like ITRS Geneos to develop an app, where instead of going to specific login terminals or logging into laptops or desktops to check alerts, we can have visibility in the app itself."
"ITRS Geneos cloud monitoring is very weak and can use improvement."
"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."
"ITRS have started to make some major changes that we haven't taken on board yet, in the creation of dashboards and more visibility of the metrics that we collect. At the moment, that's something that's lacking, but I know they have addressed it. Still, it’s not that easy to create stuff to help with visibility and dashboarding in Geneos."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"Technical support is an area that needs improvement. It is not available 24/7."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"I would like to see support for notification via SMS."
"The user interface needs improvement."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The tool's AI model needs to be fixed."
 

Pricing and Cost Advice

"Based on feedback from colleagues and friends working in the financial sector, Geneos is relatively costly. Many companies have been switching from Geneos to Dynatrace, Sysdig, or other monitoring tools in the past two years because of the price."
"The organization is not just purchasing a license for the product, but also managing services and professional services from ITRS. Another factor is if the implementation is going to be in production, non-production, or both."
"The pricing is fairly market-related. They have been very lenient because we have been working with them for so long. An example is that we're currently migrating some of our services to AWS, and they've given us a grace period for some of the things to help with the migration and not to grow additional costs while we are migrating, but it's still on par with the market."
"ITRS Geneos is not a cheap tool. It's a moderate price for the banking industry. The reason we are not able to add the ITRS monitoring tool for the non-banking industries, and non-finance industries, is that the pricing is too high."
"The licensing cost may seem expensive upfront. However, the service is outstanding, the tool does things that no other tools can do, and the customizability more than makes up for the cost of licensing."
"Its price is reasonable. It isn't too expensive, and it isn't too cheap, but it also depends on a company's volume and negotiation."
"Given our spend and the amount of service we have in it, the pricing is quite reasonable."
"I can say it's not that cheap because the licensing is a little bit costly"
"As it is not an agentless tool, I think it is expensive."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"Nagios XI is an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is open source."
"Licensing costs are reasonable."
