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

"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."

"Tons of default modules which are available out of the box"

"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 ability to logically normalize data gathered from multiple types of sources via pre-built plugins is extremely powerful. This functionality, coupled with the ability to import custom data via the Toolkit plugin allows Geneos to be leveraged to monitor every system in the enterprise."

"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."

"Real-time log monitoring with desktop alerts is valuable as it tells us immediately when there is an issue."

"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."

More ITRS Geneos pros

"We use the product to monitor server applications."

"Key features include the GUI interface, its notification capabilities, and the real-time reporting."

"Provides timely notifications."

"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."

"The good thing about Nagios Core is it covers everything."

"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."

"We mostly use Nagios Core to integrate with Python and Bash Script."

"The application performance monitoring feature is valuable."

More Nagios Core pros

Cons

"A lightweight version which could host more than 100 gateways, as we can see slowness while loading all our gateways."

"Currently, it is difficult to monitor secure websites using SSL or with SSO enabled."

"Much of the reporting outside of the user interface is very basic and requires much customization to be useful."

"I would like to see ITRS integrate its setup editor with a SVN to check-in setup XML after major changes."

"The dashboard feature is full of bugs. Grouping items results in a distorted dashboard."

"I would like better access to the data that is being collected."

"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."

"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."

More ITRS Geneos cons

"The dashboard should be improved."

"The scalability needs improvement, it's not scalable at this time."

"The dashboard and monitoring features could be improved."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"I believe Nagios Core will need to provide an option for big data platforms in the future."

"The mapping is a little hard."

"Nagios Core does not have a graphic display."

"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."

More Nagios Core cons

Pricing and Cost Advice

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

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

"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."

"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."

"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."

"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."

"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."

More ITRS Geneos pricing and cost advice

"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."

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

"The solution is expensive."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"The enterprise version has technical support. The version we are using is free."

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

"We are using the free version."
