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

"Real-time log monitoring with desktop alerts is valuable as it tells us immediately when there is an issue."
"The ability to build integrations to tools that are not monitored out of the box is the most valuable feature."
"One of the most valuable features of ITRS Geneos is the active time feature that helps with the trading applications that I support."
"The NetProbe carries over 100 samplers which are capable of monitoring hardware, OS, and the application layer."
"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."
"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)."
"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."
"The Netprobe is so lightweight compared to the agents that most monitoring tools use. It's really superior to the competition. The agent that is used by almost every competitive tool takes a lot more system resources. It's slower and it requires a greater effort and more compromises in terms of security to install on the monitored servers. With Geneos, because it lives outside the code, it is far easier and far less taxing on the monitored systems."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"The solution is quite efficient."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"The good thing about Nagios Core is it covers everything."
"Dashboard provides monitor of total assets."
"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."
"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."
 

Cons

"Backward compatibility with deprecated features and in system documentation on what configuration areas are needed to be updated."
"t needs to have better middleware integration for things such as application and Microsft SQL servers."
"Currently, it is difficult to monitor secure websites using SSL or with SSO enabled."
"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."
"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."
"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."
"ITRS Geneos is not on the cloud at a time when everyone is moving to the cloud."
"Much of the reporting outside of the user interface is very basic and requires much customization to be useful."
"The core version is no match for the XI version."
"The tool needs to improve the integrations."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The UI is a little outdated and graphics could be displayed in a better way."
"Would benefit from aggregations if a particular server goes down."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The dashboard and monitoring features could be improved."
 

Pricing and Cost Advice

"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 and licensing is based on the requirements."
"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."
"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."
"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."
"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."
"The licensing cost may seem expensive upfront. However, the service is outstanding, the tool does things that no other tools can do, and the customizability more than makes up for the cost of licensing."
"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."
"We are using the free version."
"It's free."
"Nagios Core is an open source solution, and there are no licensing fees."
"Lessening the price point would be an improvement."
"We are using the free version of Nagios Core."
"Nagios Core is free to use."
"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."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
