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 confidence of our users has greatly improved because of our ability to react much faster."
"The Geneos monitoring solution is a mature industry standard monitoring solution, and is present in over 90% of the invest banks in the city."
"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."
"It’s very easy to install and setup, offers high scalability, and has a low resource use."
"One of the benefits is to have 24/7 automated monitoring of our most critical services; in general, it has drastically increased the visibility of our estate, definitely improved our response times to issues, and enabled us to proactively detect issues and prevent outages as well."
"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."
"Customer Service: Very good. Technical Support: Very good."
"The clean and colorful UI and easy to use options like snooze and active times."
"I can monitor a phone on a desk to very big servers of any company."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"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."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"It's great for monitoring IT services infrastructure."
"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
 

Cons

"We were a little bit confused but once we found out what was needed, it was smooth."
"Data visualization – real time and historical – is a weakness."
"Backward compatibility with deprecated features and in system documentation on what configuration areas are needed to be updated."
"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."
"Currently the dashboard does not have the capability of providing different status levels, and this needs to be updated."
"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."
"The interface can sometimes be a little complicated."
"Mobile phone integration is probably not as rich as it could be."
"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."
"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"It's in need of more standard plug-ins."
"The Configuration Wizard needs improvement, because not all vendors are present."
"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"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."
 

Pricing and Cost Advice

"Given our spend and the amount of service we have in it, the pricing is quite reasonable."
"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 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."
"You will get the best price if you get a single global deal."
"Pricing and licensing is based on the requirements."
"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."
"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 seems reasonable. We're happy enough with it."
"We are using the free version of this solution."
"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."
"As it is not an agentless tool, I think it is expensive."
"The pricing is high with separate licensing for the product and support."
"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."
"Nagios XI is open source."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
