Featured Reviews

Sanket - PeerSpot reviewer
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.

Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

Quotes from Members

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

Pros

"Tons of default modules which are available out of the box"
"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)."
"One of the most valuable features of ITRS Geneos is the active time feature that helps with the trading applications that I support."
"I always appreciate Geneos's stability and ease of use."
"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."
"The NetProbe carries over 100 samplers which are capable of monitoring hardware, OS, and the application layer."
"Custom script toolkits"
"The ability to logically normalize data gathered from multiple types of sources via pre-built plugins is extremely powerful. This functionality, coupled with the ability to import custom data via the Toolkit plugin allows Geneos to be leveraged to monitor every system in the enterprise."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"It's great for monitoring IT services infrastructure."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The solution's most valuable feature is its simplicity."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
 

Cons

"I would really like to see something from the Geneos side to set up automated reporting from ITRS. We have to send reporting to management every day. To do that we have to check the dashboard and then we have to report whether everything is fine or not. In the future, I want something, some reporting kind of feature in ITRS, where it can collect all the data and mention what is green, what is amber, what is red in a report."
"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."
"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."
"A lightweight version which could host more than 100 gateways, as we can see slowness while loading all our gateways."
"Backward compatibility with deprecated features and in system documentation on what configuration areas are needed to be updated."
"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."
"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The user interface needs improvement."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"It can be quite difficult to know which drivers and agents to use when setting up."
 

Pricing and Cost Advice

"The pricing seems reasonable. We're happy enough with it."
"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."
"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 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 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 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."
"Pricing and licensing is based on the requirements."
"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."
"We are using the free version of this solution."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"Nagios XI is open source."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"The pricing is high with separate licensing for the product and support."
