AI-driven insights have reduced downtime and improved cross-team collaboration
We encountered some challenges while using Dynatrace. Although the initial setup was smooth, fine-tuning alert thresholds and custom metrics took some time. Another challenge was that Dynatrace charges based on host units, so we had to carefully plan our agent deployments. The licensing model is expensive. Additionally, the complexity of setup is an issue. While OneAgent and auto-discover services are powerful, the setup is more complex compared to other tools such as Prometheus and Grafana. These integrations are simple and basic, but Dynatrace setup requires more complexity based on the environment. For new users wanting to use Dynatrace, it is difficult. However, the AI-related solutions and metrics took us to the next level for identifying and fixing things. Dynatrace requires an agent for operation. OneAgent is powerful, but it is also resource-heavy. On lightweight nodes or older systems, the agent can slightly impact performance. If Dynatrace could implement a lightweight agent behavior, we could make things faster. Additionally, if Dynatrace could add a long-term retention policy so that we could store more data and find fine-grained details, that would help us. While Dynatrace managed edition supports on-premises deployment, the SaaS version depends on cloud connectivity. For highly regulated or air-gapped environments, setup and updates can be challenging. Although the initial setup is smooth, if someone wants to fine-tune it and fully understand the tool end-to-end, it could be tricky.

A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"We used AppDynamics, and our challenges using siloed monitoring revolved around integration because you needed more manpower to manage things, but now with Dynatrace it is just a few clicks and it scales up, which makes a big difference."
"Mean time to root cause analysis decreased drastically."
"We scaled from 300 agents to 800 agents in six months. There were no issues at the server level, which is pretty good.​"
"Our company gets quick response times and qualified responses from technical support, so that is good."
"The big data analytics is the most powerful tool at my disposal, and with the analytics, I can review behaviors, trending issues, and resolve issues before they impact our clients."
"The technical support has always been responsive."
"It used to take a lot of time to troubleshoot, but now, with Dynatrace, we can actually see the logs anytime we want, quickly find the problem, and it has improved performance from a time perspective."
"Since we moved to OneAgent, we are much quicker to address live incidents and problems that occur in our systems."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"Under heavyweight, Dynatrace becomes slower when listing PurePaths."
"Two things that can be improved are the licensing and the Business dashboard."
"They need to improve on claims about being an enterprise system."
"Dashboards and monitoring capabilities can be improved for monitoring applications in Azure. In Azure, it would be cool to be able to monitor network consumption as well as flow communication."
"We have some issues with react user sessions."
"Network monitoring is lacking and could be improved."
"This tool had a feature of doing load test in production or lower environment, which was shut down earlier this year. We are missing that feature badly and we definitely want to see that feature back."
"We would like to see an AI tool that detects issues with our site in real time."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
"The initial setup of the solution is a little bit difficult."
 

Pricing and Cost Advice

"Its license is a bit expensive. We renew it yearly."
"​I would recommend doing a PoC."
"Consider volume because that is where you will get the most benefit. Doing a point solution is not cost-effective."
"The solution is not cheap."
"The price range is quite high."
"​Do a PoC and see if you like it."
"Dynatrace is still kind of an expensive solution compared to others. But I recognize that they are ahead of the competition when we do a feature by feature comparison."
"We have a three-year contract. We have 30 licenses for the full stack and 3 licenses for the DEM unit."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
"It is an open-source solution."
