The flexible dashboard sets it apart from competing tools, but it's costly and lacks scalability
Geneos provides near-real-time data if the underlying infrastructure is sufficient. The time to get a response depends on the kind of alert you set. All monitoring tools have multiple alert methods. You can receive an alert within the tool where it flags the issue on the dashboards. You get real-time alerts in Geneos. You can also receive alerts via email. That is quick unless your email system has some delay latency. Geneos sends alerts within 20 to 30 seconds. It will throw the alert to your inbox and 13 chatbots. You can configure Geneos with chatbots also in real-time. The primary benefit to our company is the dashboard. We have a management dashboard that highlights business-critical alerts to management. We have a high-level dashboard for management and a technical dashboard for L2 and L3 engineers. The help desk and other L1 departments have their own dashboard. The dashboard has improved our business significantly because it provides visibility into the entire operation from one screen. It offers a traffic-light mechanism. When there is an issue in North America or South America, Geneos immediately alerts you and the management that there is something we need to look into. Geneos can predict and resolve problems through automation. Geneos will automatically restore the service several times when a service goes down based on our configuration. It prevents a couple of outages each month where the services do not come back online following a server restart.

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

"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."
"The biggest benefit of Geneos is the fact that we can clearly see, if we have an alert, where that alert has come from. We can see the data around that alert and anything that might be relevant is also shown. We can very easily right-click and see why we've received that alert. That's the best part about it, that you've got all the data there with the alerting."
"The great advantage of this tool is real-time monitoring."
"The solution is used across the entire investment banking division, covering environments such as electronic trading, algo-trading, fixed income, FX, etc. It monitors that environment and enables a bank to significantly reduce down time. Although hard to measure, since implementation, we have probably seen some increased stability because of it and we have definitely seen teams a lot more aware of their environment. Consequently, we can be more proactive in challenging and improving previously undetected weaknesses."
"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)."
"ITRS uses SNMP to communicate with our devices as well as SNMP net probes installed on our servers."
"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."
"The application performance monitoring feature is valuable."
"The reporting structure and the feature set are valuable to me."
"Nagios Core is very configurable. Whatever you want, you can do it."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"I like the way the solution sends alerts and how it keeps on escalating them."
"Provides timely notifications."
 

Cons

"Data visualization – real time and historical – is a weakness."
"One area where there is room for improvement is the log file. I would like to be able to do a pre-run on the log files. When you are testing log files for regular expressions, it would be good to be able to do a quick check up front on that side of things before you release that into production."
"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."
"​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 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."
"One thing that could be improved in terms of rapid scaling would be more ability to clone aspects of an implementation. It seems like there are opportunities in this area, where we have repetitive tasks to do when it comes to implementing things on new servers or on new gateways. It would be great if there was an easy way to clone something that had already been done."
"ITRS Geneos cloud monitoring is very weak and can use improvement."
"It is a bit slow due to latency."
"There is room for improvement in the graphics."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"The core version is no match for the XI version."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"The user interface could be more interactive because it is pretty basic."
"The alerting mechanism in Nagios Core could be improved."
"The interface could be improved."
 

Pricing and Cost Advice

"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."
"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."
"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."
"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."
"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."
"The pricing seems reasonable. We're happy enough with it."
"Given our spend and the amount of service we have in it, the pricing is quite reasonable."
"Pricing and licensing is based on the requirements."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Most the plugin features are free."
"The enterprise version has technical support. The version we are using is free."
"Lessening the price point would be an improvement."
"Nagios Core is a cheap solution."
"I would rate the solution's pricing an eight out of ten."
"Nagios Core is free to use."
"It's free."
