Executive SummaryUpdated on Oct 9, 2024

ITRS Geneos and Nagios Core are competitors in the monitoring solutions category. ITRS Geneos seems to have the upper hand with its real-time insights and extensive integration capabilities, while Nagios Core offers flexibility with significant customization through its open-source platform.

Features: ITRS Geneos provides real-time monitoring with comprehensive integration capabilities and customizable dashboards. It offers real-time insights and issue prediction to reduce latency. Nagios Core, as an open-source solution, allows significant customization and supports various monitoring needs. It offers infrastructure monitoring and rudimentary application checks.

Room for Improvement: ITRS Geneos needs enhanced historical data reporting and better cloud monitoring. Users seek improved middleware integration and dashboard flexibility. Nagios Core should address its steep learning curve due to the complex configuration process, and users desire a more user-friendly UI and cloud integration.

Ease of Deployment and Customer Service: ITRS Geneos mainly supports on-premises installations with recognized customer service proficiency, though faster response times are desired. Nagios Core supports on-premises and hybrid environments with a community-driven support model, fostering self-sufficiency due to limited direct vendor support.

Pricing and ROI: ITRS Geneos, noted for its higher cost, is justified by its capabilities and customizability, proving beneficial in environments where downtime is costly. Nagios Core is a free solution, avoiding licensing costs but may require significant investment in customization to match commercial offerings. It is resource-intensive due to specialized configurations for effective setup.

Featured Reviews

Sanket - PeerSpot reviewer
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.

Nishith-Vyas - PeerSpot reviewer
Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

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

Pros

"Custom script toolkits"
"One of the most valuable features is that it can be configured by non-developers. It doesn't require development expertise to configure it."
"One thing we're utilizing in Geneos is the Gateway-SQL. That's really helpful for us. Using Gateway-SQL, we are able to merge two different views into one. Suppose we have to check something in the log and that we have to check something in the database and do a comparison before publishing a result. We can achieve that using Gateway-SQL."
"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."
"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."
"One of the most valuable features of ITRS Geneos is the active time feature that helps with the trading applications that I support."
"I always appreciate Geneos's stability and ease of use."
"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."
More ITRS Geneos pros
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"The most valuable feature is the performance parameters of the system."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

Cons

"A lightweight version which could host more than 100 gateways, as we can see slowness while loading all our gateways."
"The ITA, the post-incident analytics, could be improved."
"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."
"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."
"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."
"Backward compatibility with deprecated features and in system documentation on what configuration areas are needed to be updated."
"The main feature that needs work is the Dashboard designer."
"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."
More ITRS Geneos cons
"The alerting mechanism in Nagios Core could be improved."
"The core version is no match for the XI version."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"The dashboard should be improved."
"The user interface could be more interactive because it is pretty basic."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"It is a bit slow due to latency."
More Nagios Core cons
 

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."
"Given our spend and the amount of service we have in it, the pricing is quite reasonable."
"Pricing and licensing is based on the requirements."
"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 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."
"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."
"You will get the best price if you get a single global deal."
