If one server fails, the agent will automatically be reinstalled
ITRS Geneos is a legacy system. It predicts or provides proactive measures once an issue is resolved. It doesn't offer any predictive capabilities or root cause analysis. They throw a lot of data if there's a 90% error. You need to check which process is consuming more CPU and determine the root cause for yourself. You need to troubleshoot it manually. This legacy system could introduce predictive analysis and root cause identification. They are reluctant to switch to newer solutions, which may require writing queries to fetch data. Manually logging into servers, checking CPU usage, identifying processes, and determining root causes is time-consuming. Once the root cause is identified, the issue can be resolved efficiently. The manual troubleshooting process is time-consuming. The content is not openly available in the market. If you search for it somewhere, it is not readily accessible. If you want to try it out, no trial version is available. Therefore, it will be challenging to learn. Loading ITRS is difficult, as you need to purchase it first. Secondly, only a few people are knowledgeable about ITRS in the market, making it challenging to find resources. Thirdly, the documentation must be well-documented, making finding content or training material hard. The UI also needs to be updated, which adds to the difficulty.

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

"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."
"It enables us to monitor application processes, to do log-monitoring on a 24/7 basis, to do server-level monitoring - all the hardware parameters - as well as monitor connectivity across applications to the interfaces."
"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."
"Custom script toolkits"
"ITRS uses SNMP to communicate with our devices as well as SNMP net probes installed on our servers."
"The remarkable feature of Geneos is the dashboard. Geneos' flexible dashboard sets it apart from other monitoring tools. Other solutions have limitations in their dashboard design and can't be customized as much. The Geneos dashboard allows unlimited creativity."
"Ability to monitor logs for potential issues to prevent app outages before problems get a chance to arise. That's invaluable for our teams in a fast-paced trading environment."
"This tool allows one to analyse, integrate and customize as per the systems and allows you to set your own rules."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"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."
"It's great for monitoring IT services infrastructure."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"The technical support is good."
"The solution is pretty stable."
"The solution has a lot of plugins and scripts integrated with it."
"The alerting system is very effective."
 

Cons

"There is a part of the rules for monitoring alerts. I want to understand more about how to choose the samples and the requirements for the rules. That is the part that I want to understand better and get better training for."
"For the solution to stay relevant in the cloud-based monitoring environment Geneos needs more plug-ins with more features. Instead of offering clients workarounds, the solution should have a cloud-based out-of-the-box version."
"Mobile phone integration is probably not as rich as it could be."
"Data visualization – real time and historical – is a weakness."
"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."
"Backward compatibility with deprecated features and in system documentation on what configuration areas are needed to be updated."
"ITRS Geneos cloud monitoring is very weak and can use improvement."
"ITRS Geneos is not on the cloud at a time when everyone is moving to the cloud."
"Open-source software is usually not user-friendly."
"We'd like to see more integration capabilities."
"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."
"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."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"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 GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
 

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 pricing seems reasonable. We're happy enough with it."
"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."
"You will get the best price if you get a single global deal."
"The product is priced quite high. There are pricing options for customers based on the size of the environment and plug-ins used by the monitoring system."
"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 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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"We are using the free version of this solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is an expensive solution."
"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."

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…
