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.

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.

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

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

"The ability to completely tailor and customize what it's monitoring is one of its strongest points. A lot of other monitoring tools are good at certain things, but one of my colleagues described it as the “Swiss Army Knife” of monitoring tools. It can do anything you want."

"ITRS can define rules to alert when certain parameters that you monitor breach a threshold. Rules can be configured to fire recovery actions automatically to clear the alert"

"One of the most valuable features of ITRS Geneos is the active time feature that helps with the trading applications that I support."

"The flexibility of the product is most valuable. It is highly customizable. If you put your mind to it and think of something you could do, there's a good possibility you can get it integrated within the console, if it's not readily available. The simplicity or ease of customization has been valuable."

"ITRS uses SNMP to communicate with our devices as well as SNMP net probes installed on our servers."

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

"It's also easy to implement. The implementation of Geneos is very easy and interesting. It's not complicated. It's very quick to implement. The installation is very easy. There are many topics about ITRS Geneos that explain more about the features of the function of Geneos."

More ITRS Geneos pros

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"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."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"The application performance monitoring feature is valuable."

"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."

"Nagios Core is very configurable. Whatever you want, you can do it."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

"The most valuable feature is the performance parameters of the system."

More Nagios Core pros

Cons

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

"Data visualization – real time and historical – is a weakness."

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

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

"Mobile phone integration is probably not as rich as it could be."

"ITRS Geneos is not on the cloud at a time when everyone is moving to the cloud."

"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."

"It needs to be easier to configure, especially with the JMX plugins."

More ITRS Geneos cons

"The dashboard should be improved."

"Would benefit from aggregations if a particular server goes down."

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."

"The core version is no match for the XI version."

"The UI is a little outdated and graphics could be displayed in a better way."

More Nagios Core cons

Pricing and Cost Advice

"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."

"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."

"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."

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

"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."

"The pricing seems reasonable. We're happy enough with it."

"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."

More ITRS Geneos pricing and cost advice

"Nagios Core is an open source solution, and there are no licensing fees."

"Lessening the price point would be an improvement."

"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."

"It's free."

"The product is cheaply priced."

"We are using the free version of Nagios Core."

"I would rate the solution's pricing an eight out of ten."
