Has provided powerful customization for unique monitoring needs but needs more out-of-the-box capabilities
In my opinion, the best features of Elastic Observability are their flexibility to integrate with other existing systems and the ability to build a unified monitoring tool that can integrate with existing ones and end-to-end user journeys which require a lot of customizations. The greatest feature in Elastic is the ability to customize. This is similar to my comments about customizable dashboards in Elastic because it's visible to the analyst. However, it's very great. Customizing these dashboards can meet the customer's specific use cases and specific stories that they have in their environment, their special environment that doesn't look like other environments. The dashboarding in Elastic is highly customizable to the level of logos. If the customer wants his company logo in the dashboard, it can be done.

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

"I think Elastic Observability is already in very good shape."
"The solution allows us to dig deep into data."
"We use AppDynamics and Elastic. The reason why we're using Elastic APM is because of the license count. It's very favorable compared to AppDynamics. It's inexpensive; it's economical."
"It has always been a stable solution."
"We can view and connect different sources to the dashboard using it."
"Its diverse set of features available on the cloud is of significant importance."
"I have built a mini business intelligence system based on Elastic Observability."
"It is a powerful tool that allows users to collect and transform logs as needed, enabling flexible visualization and analysis."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"We use Security Onion for internal vulnerability assessment."
"Security Onion is the most mature solution in the market."
 

Cons

"In the future, Elastic APM needs a portfolio iTool. They can provide an easy way to develop the custom UI for Kibana."
"Simplifying the parsing of logs and manual efforts would also be beneficial."
"The cost must be made more transparent."
"The tool's scalability involves a more complex implementation process. It requires careful calculations to determine the number of nodes needed, the specifications of each node, and the configuration of hot, warm, and cold zones for data storage. Additionally, managing log retention policies adds further complexity. The solution's pricing also needs to be cheaper."
"Elastic Observability could improve asset discovery as the current requirement to push the agent is not ideal."
"Elastic APM's visualization is not that great compared to other tools. It's number of metrics is very low."
"Elastic Observability’s price could be improved."
"It lacked some capabilities when handling on-prem devices, like network observability, package flow analysis, and device performance data on the infrastructure side."
"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"Users have to pay for some features, like the alerts on different channels, because they are unavailable in different source versions."
"One needs to pay for the licenses, and it is an annual subscription model right now."
"So far, there are just the standard licensing fees. Several of the components are embedded in the license or are even open source. They're even free depending on what you use, which makes it even more appealing to someone that is discussing pricing of the solution."
"We will buy a premium license after POC."
"There are two types: cloud and SaaS. They charge based on data ingestion, ingest rate, hard retention, and warm retention. I believe it costs around $25,000 annually to ingest 30GB of data daily. That is the SaaS version. There is also a self-managed license where the customer manages their own infrastructure on-prem. In such cases, there are three license tiers that respectively cost $5,000 annually per node, $7,000 per node, and $12,500 per node."
"Elastic Observability's pricing could be better for small-scale users."
"Since we are a huge company, Elastic Observability is an affordable solution for us."
"The price of Elastic Observability is expensive."
"It is an open-source solution."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
