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.

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

"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."
"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."
"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"
"This tool allows one to analyse, integrate and customize as per the systems and allows you to set your own rules."
"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 ability to build integrations to tools that are not monitored out of the box is the most valuable feature."
"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."
"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."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"Nagios Core is stable."
"The solution is quite efficient."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"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 features are the reports and the way it generates the report in a graphical manner."
 

Cons

"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."
"Much of the reporting outside of the user interface is very basic and requires much customization to be useful."
"At the moment Geneos is excellent and handling real time monitoring, however not great at doing historical reporting."
"I would like to see ITRS integrate its setup editor with a SVN to check-in setup XML after major changes."
"Currently, it is difficult to monitor secure websites using SSL or with SSO enabled."
"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."
"We all look at the same things - CPU, disk space, paging stats, service status with RAG status on each. That could be provided straight out, saving significant time."
"t needs to have better middleware integration for things such as application and Microsft SQL servers."
"The initial setup process could be easier."
"The core version is no match for the XI version."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The dashboard should be improved."
"The user interface could be more interactive because it is pretty basic."
"The dashboard and monitoring features could be improved."
"It is a bit slow due to latency."
"Nagios Core can improve the graphical interface, it would make things a little easier."
 

Pricing and Cost Advice

"Pricing and licensing is based on the requirements."
"You will get the best price if you get a single global deal."
"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."
"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 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."
"Given our spend and the amount of service we have in it, the pricing is quite reasonable."
"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."
"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."
"We are using the free version."
"It's free."
"Lessening the price point would be an improvement."
"Nagios Core is an open source solution, and there are no licensing fees."
"The enterprise version has technical support. The version we are using is free."
"The solution is expensive."
"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."
"Nagios Core is free to use."
