Director at Bitrate

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.

Dhananjay Dileep

Senior Software Engineer at a consultancy with 10,001+ employees

Unified monitoring has improved end-to-end visibility and reduced detection time across apps

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. Additionally, it throws random errors; for example, when we try to save one detector, it might throw some random error which is not even related, with something else being wrong, not that particular error, but the underlying root cause might be different. Sometimes the error is just "some problem occurred," and we are not able to point out what the real cause is. This mainly happens when we have too many detectors or too many alerts in place rather than a standard number. One more thing is in the alert rules; if we have a main general alert, and instead of creating a new detector, we are adding a new rule under one detector, when the number of rules also increases, such as when we have 10 or 15 rules under one generic detector, that again creates the same kind of problem, taking some time to save that particular newly added rule, and it might not save at times, just keeps on spinning. Those are the two drawbacks which I spotted recently; other than that, everything looks perfect.

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."

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

"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."

"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 product retains a lot of log data for subsequent analysis."

"The initial setup of Splunk Real User Monitoring (RUM) was easy."

"After moving to Splunk Observability Cloud, it is almost zero downtime."

"Overall, I would recommend Splunk to anyone seeking a monitoring solution, thanks to its extensive capabilities and features."

"The tool's stability is great."

"The most valuable feature is dashboard creation."

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

"Dashboards help the application support teams to have a quick look at how their systems are running. It helps other teams as well."

Cons

"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."

"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."

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

"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."

"We currently lack log analysis capabilities in Splunk APM."

"There is room for improvement in customer support due to delays and standard feedback responses."

"The solution's machine learning deployment is hard and should be made user-friendly."

"Support from Splunk is not very helpful because Splunk doesn't have a dedicated APM; they only have one APM engineer in Korea."

"In Splunk Observability Cloud, I notice room for improvement in synthetic monitoring. It does not provide output based on server names."

"It would be useful if they provided some help pages. If you don't know too much about the tool, there should be more documentation readily available. It would be useful if they had a help button embedded in the solution so you could ask questions and get answers."

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

"Integrating some third-party add-ons can be challenging, involving many implementation and configuration steps."
