If one server fails, the agent will automatically be reinstalled
ITRS Geneos is a legacy system. It predicts or provides proactive measures once an issue is resolved. It doesn't offer any predictive capabilities or root cause analysis. They throw a lot of data if there's a 90% error. You need to check which process is consuming more CPU and determine the root cause for yourself. You need to troubleshoot it manually. This legacy system could introduce predictive analysis and root cause identification. They are reluctant to switch to newer solutions, which may require writing queries to fetch data. Manually logging into servers, checking CPU usage, identifying processes, and determining root causes is time-consuming. Once the root cause is identified, the issue can be resolved efficiently. The manual troubleshooting process is time-consuming. The content is not openly available in the market. If you search for it somewhere, it is not readily accessible. If you want to try it out, no trial version is available. Therefore, it will be challenging to learn. Loading ITRS is difficult, as you need to purchase it first. Secondly, only a few people are knowledgeable about ITRS in the market, making it challenging to find resources. Thirdly, the documentation must be well-documented, making finding content or training material hard. The UI also needs to be updated, which adds to the difficulty.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Quotes from Members

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

Pros

"I would say that it is an easy-to-use monitoring tool. Amongst the available monitoring tools, it is a really good option."
"The great advantage of this tool is real-time monitoring."
"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."
"Ability to monitor logs for potential issues to prevent app outages before problems get a chance to arise. That's invaluable for our teams in a fast-paced trading environment."
"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 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."
"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."
"I like the way the solution sends alerts and how it keeps on escalating them."
"The good thing about Nagios Core is it covers everything."
"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 most valuable feature is the performance parameters of the system."
"Provides timely notifications."
"Dashboard provides monitor of total assets."
"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."
"Nagios Core is stable."
 

Cons

"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."
"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."
"t needs to have better middleware integration for things such as application and Microsft SQL servers."
"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."
"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."
"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."
"Much of the reporting outside of the user interface is very basic and requires much customization to be useful."
"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"There is room for improvement in the graphics."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"I would like to see more training videos."
"Nagios Core does not have a graphic display."
"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."
"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."
 

Pricing and Cost Advice

"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."
"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 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."
"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."
"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."
"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 product is cheaply priced."
"Nagios Core is an open source solution, and there are no licensing fees."
"Nagios Core is a cheap solution."
"The enterprise version has technical support. The version we are using is free."
"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."
"I would rate the solution's pricing an eight out of ten."
"It's free."
