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

"This is the most amazing monitoring tool I've ever worked with, because it allows you to monitor a lot of things and also to address the issue and assign it to someone so everyone will know it's being investigated."
"As a company looking to onboard, its capacity to monitor just about anything from Unix log files and processes to database memory, and even run queries and provide results, means it can be used as a one stop shop for all your monitoring needs if you understand how to utilise it to its fullest extent."
"Real-time log monitoring with desktop alerts is valuable as it tells us immediately when there is an issue."
"In my experience, being able to monitor our databases is a valuable feature as we can create our own queries and aren't reliant on the in-built ones."
"Tons of default modules which are available out of the box"
"It's catching things that are going wrong before they become catastrophic, in most cases."
"The clean and colorful UI and easy to use options like snooze and active times."
"ITRS Geneos provides peace of mind by mentoring our processes and applications."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"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, and you can customize the solution by adding additional features using code."
"This is a very good solution and it is simple to use, for any company."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"It is an open-source platform with valuable features for performance and stability."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
 

Cons

"I would like to see ITRS integrate its setup editor with a SVN to check-in setup XML after major changes."
"Mobile phone integration is probably not as rich as it could be."
"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."
"The ITA, the post-incident analytics, could be improved."
"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."
"I had issues scaling it and ended up having to distribute the load over seven gateways."
"ITRS Geneos cloud monitoring is very weak and can use improvement."
"Their cloud monitoring solution needs to be improved. I have already given them the feedback that it's not capable of meeting the latest technology needs."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"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."
"There's room for improvement in the visibility, and in the ability to extract information."
"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."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The GUI could be improved."
"They need to develop a better integration with a common ticketing system will be great."
 

Pricing and Cost Advice

"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."
"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."
"Pricing and licensing is based on the requirements."
"When I first came in, their pricing was very high. ITRS had a high expectation of what their price should be based on perceived value. I think they have been realizing, more recently, that there are other competitors, so their pricing is a lot better. Licensing for on-premise is okay, however I feel there is quite some work to be done for cloud and containers. We're still working with them to try and work out what that pricing should look like."
"You will get the best price if you get a single global deal."
"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"
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"As it is not an agentless tool, I think it is expensive."
"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 pricing is high with separate licensing for the product and support."
"Nagios XI is open source."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The licensing fees for this solution are approximately $3,000 USD per year."
