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.

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

"Geneos automatically sends email notifications when any batch job fails, the database is down or the website is down; it is automatically monitoring everything and reduces manual effort."
"Custom script toolkits"
"Customizable Dashboard to display real time business flow monitoring is extremely useful to operations as well as business users, not only to monitor health but also capacity and performance at a glance, catering well to capital markets trading environments from on-exchange order latency to client RFQ type multi-stage tracking, with Geneos providing tools to capture data in near real-time and highly customizable ingestion of metrics that allow users to create tailored scripts and tools for their monitoring needs."
"Geneos enables customized aggregate views and alerts for both related and disparate components, and this flexibility and insight facilitates proactive and prompt causation analysis so you can easily see everything at once and know why there is an issue within seconds rather than spend precious time trying to find out."
"One of the best aspects of Geneos is that it has a broad scope and can cover a lot of use cases. You can write your own scripts to monitor really specific things. And the rules that you can put in place can be quite complex for the alerts."
"We previously used Nagios, but switched to Geneos as it has better monitoring for applications, and it has more features and better configuration possibilities."
"The solution's log monitoring and alerting mechanisms are very user-friendly and easy to plug and play."
"It's a great and powerful tool."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"The ROI is very good."
"This is a very good solution and it is simple to use, for any company."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The solution is pretty stable."
"I really found Nagios a perfect fit for us and a good product to work with."
"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 can monitor a phone on a desk to very big servers of any company."
 

Cons

"There is are issues with the compatibility of plugins with AIX servers."
"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."
"Backward compatibility with deprecated features and in-system documentation on what configuration areas are needed to be updated can be improved."
"There is one drawback to using lightweight data collection: we lack the feature of observability based on time series, such as historical model data. This makes it difficult to view data in ITRS. ITRS needs to improve this feature."
"The initial setup was a bit complex."
"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."
"We were a little bit confused but once we found out what was needed, it was smooth."
"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."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"It can be quite difficult to know which drivers and agents to use when setting up."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"The installation can get very difficult depending on what Linux flavour you are using."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"The interface could be more user-friendly."
 

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 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."
"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."
"I can say it's not that cheap because the licensing is a little bit costly"
"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."
"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."
"Pricing and licensing is based on the requirements."
"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."
"Nagios XI is an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is high with separate licensing for the product and support."
"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."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"As it is not an agentless tool, I think it is expensive."
