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.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Quotes from Members

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

Pros

"ITRS can define rules to alert when certain parameters that you monitor breach a threshold. Rules can be configured to fire recovery actions automatically to clear the alert"
"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)."
"This solution has helped provide relief to existing Level 2 teams, allowing them to focus efforts on in-depth problem analysis."
"The clean and colorful UI and easy to use options like snooze and active times."
"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."
"I always appreciate Geneos's stability and ease of use."
"This tool allows one to analyse, integrate and customize as per the systems and allows you to set your own rules."
"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."
"The good thing about Nagios Core is it covers everything."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"Nagios Core is stable."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"Provides timely notifications."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"The reporting structure and the feature set are valuable to me."
 

Cons

"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."
"​It needs to be easier to configure, especially with the JMX plugins.​"
"Geneos' application monitoring could be improved a lot. Products like AppDynamics and Dynatrace provide the process thread-level monitoring, but Geneos lacks these capabilities."
"The ITA, the post-incident analytics, could be improved."
"At the moment Geneos is excellent and handling real time monitoring, however not great at doing historical reporting."
"There is a part of the rules for monitoring alerts. I want to understand more about how to choose the samples and the requirements for the rules. That is the part that I want to understand better and get better training for."
"A lightweight version which could host more than 100 gateways, as we can see slowness while loading all our gateways."
"Their cloud monitoring solution needs to be improved. I have already given them the feedback that it's not capable of meeting the latest technology needs."
"The initial setup process could be easier."
"The UI is a little outdated and graphics could be displayed in a better way."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"It is a bit slow due to latency."
"The alerting mechanism in Nagios Core could be improved."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"Would benefit from aggregations if a particular server goes down."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
 

Pricing and Cost Advice

"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."
"ITRS Geneos is not a cheap tool. It's a moderate price for the banking industry. The reason we are not able to add the ITRS monitoring tool for the non-banking industries, and non-finance industries, is that the pricing is too high."
"You will get the best price if you get a single global deal."
"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."
"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."
"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 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 Core is free to use."
"We are using the free version of Nagios Core."
"The solution is expensive."
"Nagios Core is an open source solution, and there are no licensing fees."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"The enterprise version has technical support. The version we are using is free."
"It's free."
"Nagios Core is a cheap solution."
