Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Unified observability has improved real-time governance and now drives data-led decisions

Log Observer Connect is embedded here, but we are facing some delays in centralized log collection and analysis, which can be further fastened. We are collecting all the data metrics and decision-making insights, but all these data-driven decisions coming from different applications are not connected somewhere. A consolidated form or correlation of these insights is not happening between each other due to which we feel we are missing something significant. Some generalized feedback includes that predictive alerts or alarms which can be integrated with AI-driven alarms and alerting features should be established so that there is AI-driven intelligence and anomaly detection happening with a complete systematic process in service delivery. Application dependencies are huge, and business and operational dashboards should be improved. Right now there are very interactive custom dashboards, and every now and then, the personalization of enhancements keeps happening. KPI monitoring, executive reporting, and analytics have definitely been introduced to a great extent. There are few things in cloud-native monitoring, such as integration with AWS and Azure, where we sometimes do face lags. Those things can definitely be improved upon. I have used Datadog and Dynatrace before using Splunk Observability Cloud. Datadog was definitely recommended by most of our peers because of its very strong comprehensive observability and very strong and unique dashboard systems. Dynatrace was also very good because they have offered a lot of AI-driven analysis methods and processes, which was helping our organization a lot. Since our organization has a very strong IT ecosystem for agriculture, very different kinds of customized things are required.

Quotes from Members

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

Pros

"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."

"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."

"Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features."

"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

"I have no regrets using this product, I am very satisfied for what I paid for it and for the things I am able to do with the product."

"If you have the opportunity, I would strongly encourage you to get it, because it makes the IT experience easier and more flexible, by providing the ability to see things in your networks like the directory packet label."

"Enables us to go back in time to capture an issue and analyze it for a solution, and this after the fact analysis is key to overcoming the bump in the night issues."

More Observer GigaStor pros

"The out-of-the-box customizable dashboards provided by Splunk Observability Cloud are effective in showcasing IT performance to business leaders."

"The most valuable features are troubleshooting and optimizing application performance."

"Customer service and technical support respond very quickly."

"We haven't really experienced any glitches or bugs."

"The initial setup was straightforward. We didn't find it to be too complex."

"This solution is very quick to deploy as it is a SaaS solution and integrates with tools like ServiceNow."

"The features I appreciate the most about Splunk Observability Cloud are the ServiceNow integration feature, which is very seamless, and that's probably my favorite since ServiceNow is big in the observability industry."

"Splunk Infrastructure Monitoring gives us complete visibility without the need for storage."

More Splunk Observability Cloud pros

Cons

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

"I would like to have more than 4TB of storage available in the portable version of this solution."

"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."

"The Observer Console UI is consistent and stable, but could use some updating to be more modern."

"The interface is pretty complex, so for the average user, it takes a while to get up to speed with it. I would like it to be more user-friendly."

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"In future updates, I would like to see more predefined monitoring query solutions, which could be more effective."

"Particularly what we're having is disconnection from the cloud console, where we will be working in it and receive a message saying that we've been disconnected and have to wait for it to come up."

"The licensing model is expensive. We need to monitor the amount of data ingested because the cost is based on the data collected."

"The clustering part of indexes can be more refined."

"The UI enhancements could be a way to improve the solution in the future."

"When we have too many detectors in place for one particular app, such as when I have created 50+ detectors through my account, the entire page becomes a bit loaded when creating the 51st detector, feeling heavy and taking time to load."

"In terms of pricing, I have one issue with Splunk Observability Cloud; in a large-scale organization, it does not have features such as cost optimization or budgeting for observability spend."

"The pricing would be one area for improvement."

More Splunk Observability Cloud cons

Pricing and Cost Advice

"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."

"It's quite expensive."

"Splunk APM is a very cost-efficient solution."

"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."

"Licensing cost is the biggest argument I get from those divesting from Splunk. There are those within our organization who say we are going to go to other tools since Splunk is too expensive."

"The price of Splunk APM is less than some of its competitors."
