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

"Real-time log monitoring with desktop alerts is valuable as it tells us immediately when there is an issue."
"The biggest benefit of Geneos is the fact that we can clearly see, if we have an alert, where that alert has come from. We can see the data around that alert and anything that might be relevant is also shown. We can very easily right-click and see why we've received that alert. That's the best part about it, that you've got all the data there with the alerting."
"The filtering in the Active Console is exceptional. Depending on the user base, some people don't want to see server-level errors, so we have filters set up in the Managed Entities view, which allow us to filter out things that certain groups don't want to see, while allowing them to see other things. It's a great real-time monitoring solution. And you can draw graphs immediately, right from the Active Console, whether they're current graphs or historical graphs."
"One of the best aspects of Geneos is that it has a broad scope and can cover a lot of use cases. You can write your own scripts to monitor really specific things. And the rules that you can put in place can be quite complex for the alerts."
"ITRS uses SNMP to communicate with our devices as well as SNMP net probes installed on our servers."
"The ability to completely tailor and customize what it's monitoring is one of its strongest points. A lot of other monitoring tools are good at certain things, but one of my colleagues described it as the “Swiss Army Knife” of monitoring tools. It can do anything you want."
"The ability to build integrations to tools that are not monitored out of the box is the most valuable feature."
"This solution has helped provide relief to existing Level 2 teams, allowing them to focus efforts on in-depth problem analysis."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"The technical support is good."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Nagios XI helped me to draw the network and check for system failures."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"An excellent solution that is easy and intuitive to implement."
"The solution's most valuable feature is its simplicity."
"The Script Module in Nagios is really easy to use and is really cost efficient."
 

Cons

"One thing that could be improved in terms of rapid scaling would be more ability to clone aspects of an implementation. It seems like there are opportunities in this area, where we have repetitive tasks to do when it comes to implementing things on new servers or on new gateways. It would be great if there was an easy way to clone something that had already been done."
"The ITA, the post-incident analytics, could be improved."
"I would also like to see suggested guidelines to accomplish a monitoring task. The issue is that ITRS is so flexible that there is more than one way to complete a task, each with benefits and disadvantages."
"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."
"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."
"ITRS Geneos is not on the cloud at a time when everyone is moving to the cloud."
"Currently, it is difficult to monitor secure websites using SSL or with SSO enabled."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"They need more documentation for the plugins."
"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."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The installation and monitoring need improvement."
 

Pricing and Cost Advice

"Given our spend and the amount of service we have in it, the pricing is quite reasonable."
"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 pricing seems reasonable. We're happy enough with it."
"Pricing and licensing is based on the requirements."
"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."
"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."
"It is expensive. They have to look at the model around when we move to cloud and how that's going to work. The licensing cost does pay off because of the improvements in support to our business."
"You will get the best price if you get a single global deal."
"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 an expensive solution."
"The pricing is high with separate licensing for the product and support."
"The licensing fees for this solution are approximately $3,000 USD per year."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"Nagios XI is open source."
"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."

I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
