In the IT infrastructure monitoring domain, ITRS Geneos and Nagios Fusion are key competitors. ITRS Geneos generally has the upper hand in terms of ease of deployment and customer service, while Nagios Fusion is preferred for its robust feature set and extensive monitoring capabilities.

Features: ITRS Geneos provides advanced real-time monitoring, comprehensive analytical tools, and deep insights into complex systems. Nagios Fusion offers data aggregation across distributed networks, centralized system overview, and customizable alerts, catering to environments with vast IT assets.

Room for Improvement: ITRS Geneos could enhance its setup simplicity, increase feature integration for broader functionality, and improve scalability for larger systems. Nagios Fusion might focus on delivering more personalized customer support, expanding its advanced analytics capabilities, and refining its user interface for better intuitiveness.

Ease of Deployment and Customer Service: ITRS Geneos requires a more detailed setup process but offers highly rated and supportive customer service to ease implementation and support.

With the help of the solution, we can predict and prevent failures

Currently, the most valuable thing for an individual is a mobile device. Since that is where people are currently tracking everything, we have multiple applications or apps that are for various products. 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. Using the ITRS Geneos app, we could see the error message during our travels or wherever we are. I would like to see the capacity of messages for forecasting increased. Since the NSE is the number one derivative stock exchange in the work for three consecutive years, the number of messages is important. We use the capacity planner in ITRS to forecast our data needs for the next two months. The planner is important because the volume of data we produce is becoming more and more volatile compared to when we first started using ITRS Geneos in 2014.

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."

"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."

"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 built-in plug-ins allow administrators to easily configure monitoring components for market data systems such as Thomson Reuters Enterprise Platform and SRLabs Wombat (formerly NYSE)."

"The clean and colorful UI and easy to use options like snooze and active times."

"I always appreciate Geneos's stability and ease of use."

"It's a very powerful application monitoring tool across the industry. Many free, open-source tools are available. There are also paid tools, but ITRS Geneos is a real-time application monitoring tool where the user can monitor, self-configure, and manage alerts through their console."

"The Netprobe is so lightweight compared to the agents that most monitoring tools use. It's really superior to the competition. The agent that is used by almost every competitive tool takes a lot more system resources. It's slower and it requires a greater effort and more compromises in terms of security to install on the monitored servers. With Geneos, because it lives outside the code, it is far easier and far less taxing on the monitored systems."

More ITRS Geneos pros

"It's very easy to manage and monitor it."

"Being open source lets us customize it for our monitoring needs, saving us money."

"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."

Cons

"The main feature that needs work is the Dashboard designer."

"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."

"The deployment method for upgrading is a bit tricky. It takes a little bit of manual effort. If that could be a bit more automated, it would help us a lot."

"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."

"Geneos' application monitoring could be improved a lot. Products like AppDynamics and Dynatrace provide the process thread-level monitoring, but Geneos lacks these capabilities."

"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."

"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 would really like to see something from the Geneos side to set up automated reporting from ITRS. We have to send reporting to management every day. To do that we have to check the dashboard and then we have to report whether everything is fine or not. In the future, I want something, some reporting kind of feature in ITRS, where it can collect all the data and mention what is green, what is amber, what is red in a report."

More ITRS Geneos cons

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."

"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."

"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."

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."

"Given our spend and the amount of service we have in it, the pricing is quite reasonable."

"You will get the best price if you get a single global deal."

"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."

"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."

"I can say it's not that cheap because the licensing is a little bit costly"

"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 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."

"The pricing is quite reasonable, especially when compared to the broader market."
