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.

Quotes from Members

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

Pros

"I always appreciate Geneos's stability and ease of use."

"Custom script toolkits"

"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."

"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."

"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"

"Ability to monitor logs for potential issues to prevent app outages before problems get a chance to arise. That's invaluable for our teams in a fast-paced trading environment."

"The solution's log monitoring and alerting mechanisms are very user-friendly and easy to plug and play."

"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."

More ITRS Geneos pros

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

"It's very easy to manage and monitor it."

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."

"Being open source lets us customize it for our monitoring needs, saving us money."

Cons

"Mobile phone integration is probably not as rich as it could be."

"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."

"ITRS Geneos cloud monitoring is very weak and can use improvement."

"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."

"The deployment method for upgrading is a bit tricky. It takes a little bit of manual effort. If that could be a bit more automated, it would help us a lot."

"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."

"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."

"A lightweight version which could host more than 100 gateways, as we can see slowness while loading all our gateways."

More ITRS Geneos cons

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."

Pricing and Cost Advice

"I can say it's not that cheap because the licensing is a little bit costly"

"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."

"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."

"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."

"Given our spend and the amount of service we have in it, the pricing is quite reasonable."

"You will get the best price if you get a single global deal."

"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."

More ITRS Geneos pricing and cost advice

"The pricing is quite reasonable, especially when compared to the broader market."
