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

"It's a great and powerful tool."
"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 good thing is you get something out of it day one, you don't need years of training, and then you can build on that."
"Real-time log monitoring with desktop alerts is valuable as it tells us immediately when there is an issue."
"It has helped us re-define the Monitoring operating model which in turn has made support teams more efficient by using features like commented snoozing on various levels, use of knowledgebase articles associated with each alert cell, metric logging for capacity monitoring etc."
"Complete end-to-end monitoring of apps and infrastructure with key performance metrics to identify and reduce transaction latencies."
"We use Geneos to monitor our own development and production environments, and due to its automation capabilities we are able to automatically restart failed processes and alert our developers to issues in our applications and infrastructure without traditional eyes on glass monitoring."
"For my application, Geneos is detecting and helping us avoid outages at least once a day."
"Nagios is the best monitoring tool that I have ever worked on."
"Nagios XI helped me to draw the network and check for system failures."
"The installation is no problem. I've installed Nagios several times."
"The solution has a lot of plugins and scripts integrated with it."
"The alerting system is very effective."
"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."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"This solution has improved our ability to determine the source of a connection failure in our network, and now we are able to monitor the service provider's router and make that determination."
 

Cons

"The main feature that needs work is the Dashboard designer."
"Backward compatibility with deprecated features and in system documentation on what configuration areas are needed to be updated."
"Data visualization – real time and historical – is a weakness."
"Its web monitoring capability is very hard to use especially if there is authentication involved."
"They have the Webslinger solution where you can see when something is alerting. It's a little bit cumbersome."
"It needs to be easier to configure, especially with the JMX plugins."
"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."
"I believe the product has to improve on reporting."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"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."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
 

Pricing and Cost Advice

"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."
"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 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."
"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."
"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."
"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."
"Given our spend and the amount of service we have in it, the pricing is quite reasonable."
"Licensing costs are reasonable."
"We are using the free version of this solution."
"As it is not an agentless tool, I think it is expensive."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is open source."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios XI is an expensive 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."
