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.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

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

Pros

"The great advantage of this tool is real-time monitoring."
"It’s very easy to install and setup, offers high scalability, and has a low resource use."
"We previously used Nagios, but switched to Geneos as it has better monitoring for applications, and it has more features and better configuration possibilities."
"ITRS is significantly better than PRTG and saves us a lot of time in development."
"The confidence of our users has greatly improved because of our ability to react much faster."
"Their customer support is first rate."
"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."
"The 'start of day' (SOD) and 'end of day' (EOD) checks were automated by using this tool, thus reducing the amount of manual work needed by almost two hours per day."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability."
"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"I really found Nagios a perfect fit for us and a good product to work with."
"If you are a mid-sied company with an eye on expansion, this solution is very good."
 

Cons

"At the moment Geneos is excellent and handling real time monitoring, however not great at doing historical reporting."
"Geneos' application monitoring could be improved a lot. Products like AppDynamics and Dynatrace provide the process thread-level monitoring, but Geneos lacks these capabilities."
"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."
"Its web monitoring capability is very hard to use especially if there is authentication involved."
"t needs to have better middleware integration for things such as application and Microsft SQL servers."
"I would like to see ITRS integrate its setup editor with a SVN to check-in setup XML after major changes."
"Much of the reporting outside of the user interface is very basic and requires much customization to be useful."
"Sometimes there were issues with the database. If the database logging was high then the gateway would be slow."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"Its simple deployment but complexity comes once you have to import more plugins."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The interface could be more user-friendly."
"We'd like to see more integration capabilities."
"The GUI could be improved."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box."
 

Pricing and Cost Advice

"The pricing seems reasonable. We're happy enough with it."
"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."
"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 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."
"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."
"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."
"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 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."
"Nagios XI is an expensive solution."
"We are using the free version of this solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is open source."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
