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

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

"The biggest benefit of Geneos is the fact that we can clearly see, if we have an alert, where that alert has come from. We can see the data around that alert and anything that might be relevant is also shown. We can very easily right-click and see why we've received that alert. That's the best part about it, that you've got all the data there with the alerting."

"Custom script toolkits"

"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"

"The filtering in the Active Console is exceptional. Depending on the user base, some people don't want to see server-level errors, so we have filters set up in the Managed Entities view, which allow us to filter out things that certain groups don't want to see, while allowing them to see other things. It's a great real-time monitoring solution. And you can draw graphs immediately, right from the Active Console, whether they're current graphs or historical graphs."

"In my experience, being able to monitor our databases is a valuable feature as we can create our own queries and aren't reliant on the in-built ones."

"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."

More ITRS Geneos pros

"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."

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

"It is fairly easy to set up, and we can monitor pretty much everything we want to."

"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 solution is quite efficient."

"The application performance monitoring feature is valuable."

"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."

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

Cons

"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."

"ITRS Geneos cloud monitoring is very weak and can use improvement."

"The ITA, the post-incident analytics, could be improved."

"For the last year or two, I've been asking the vendor about the mobile app. This is something that probably everyone asks when they see the tool and they see how powerful it is. If there is any mobile app for this or if there is any way this tool can be more easily accessible other than having a big client installed, it would be great. I know you can build dashboards, et cetera, but there is no quick and easy way. I should be able to download an app, log in, and see my status. That will put this product above everything else out there. I believe it's on their roadmap."

"Sometimes, if there is a lot of data coming onto the servers, we have observed a little bit of slowness on the gateway servers which are doing the ITRS dashboard monitoring."

"At the moment Geneos is excellent and handling real time monitoring, however not great at doing historical reporting."

"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."

More ITRS Geneos cons

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

"The user interface could be more interactive because it is pretty basic."

"The dashboard should be improved."

"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 initial setup process could be easier."

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

"I would like to see more training videos."

More Nagios Core cons

Pricing and Cost Advice

"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."

"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 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."

"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."

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

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

"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."

More ITRS Geneos pricing and cost advice

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

"The product is cheaply priced."

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

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

"Lessening the price point would be an improvement."

"Nagios Core is a cheap solution."

"Most the plugin features are free."

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