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

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

"The solution's log monitoring and alerting mechanisms are very user-friendly and easy to plug and play."

"The solution is used across the entire investment banking division, covering environments such as electronic trading, algo-trading, fixed income, FX, etc. It monitors that environment and enables a bank to significantly reduce down time. Although hard to measure, since implementation, we have probably seen some increased stability because of it and we have definitely seen teams a lot more aware of their environment. Consequently, we can be more proactive in challenging and improving previously undetected weaknesses."

"The ability to build integrations to tools that are not monitored out of the box is the most valuable feature."

"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."

"One of the most valuable features is that it can be configured by non-developers. It doesn't require development expertise to configure it."

"The NetProbe carries over 100 samplers which are capable of monitoring hardware, OS, and the application layer."

"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)."

More ITRS Geneos pros

"Dashboard provides monitor of total assets."

"Nagios Core is stable."

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

"The reporting structure and the feature set are valuable to me."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

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

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."

"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."

More Nagios Core pros

Cons

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

"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."

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

"One area where there is room for improvement is the log file. I would like to be able to do a pre-run on the log files. When you are testing log files for regular expressions, it would be good to be able to do a quick check up front on that side of things before you release that into production."

"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."

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

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

"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

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"It is a bit slow due to latency."

"The tool needs to improve the integrations."

"There is room for improvement in the graphics."

"The mapping is a little hard."

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

More Nagios Core cons

Pricing and Cost Advice

"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."

"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."

"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."

"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."

"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."

"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."

"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."

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

More ITRS Geneos pricing and cost advice

"Lessening the price point would be an improvement."

"It's free."

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

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

"The solution is expensive."

"It's free."

"Most the plugin features are free."

"Nagios Core is a cheap solution."
