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.

A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Quotes from Members

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

Pros

"Geneos automatically sends email notifications when any batch job fails, the database is down or the website is down. It is automatically monitoring everything and reduces manual effort."
"The solution's log monitoring and alerting mechanisms are very user-friendly and easy to plug and play."
"One of the most valuable features is that it can be configured by non-developers. It doesn't require development expertise to configure it."
"This solution has helped provide relief to existing Level 2 teams, allowing them to focus efforts on in-depth problem analysis."
"I would say that it is an easy-to-use monitoring tool. Amongst the available monitoring tools, it is a really good option."
"The clean and colorful UI and easy to use options like snooze and active times."
"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."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"Being open source lets us customize it for our monitoring needs, saving us money."
"It's very easy to manage and monitor it."
 

Cons

"ITRS Geneos cloud monitoring is very weak and can use improvement."
"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."
"The ITA, the post-incident analytics, could be improved."
"At the moment Geneos is excellent and handling real time monitoring, however not great at doing historical reporting."
"Mobile phone integration is probably not as rich as it could be."
"The dashboard feature is full of bugs. Grouping items results in a distorted dashboard."
"There is one drawback to using lightweight data collection: we lack the feature of observability based on time series, such as historical model data. This makes it difficult to view data in ITRS. ITRS needs to improve this feature."
"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."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
 

Pricing and Cost Advice

"The pricing seems reasonable. We're happy enough with it."
"The market tools are on par with this solution, but if the solution included more features, then it would be well within the range for the cost."
"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."
"Pricing is the touchy subject, even here. Upper management always wants us to find a cheaper solution. But we have so much integrated with ITRS... It's expensive, but it does its job very well. And you set it and go."
"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."
"Pricing and licensing is based on the requirements."
"The pricing is quite reasonable, especially when compared to the broader market."
