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 found Elk to be excellent for log analytics, security analytics, application code-level analytics, collaboration with DevOps teams, CI/CD, microservices, and Kubernetes, specifically cloud-native or cloud-specific tasks."

"Machine learning is the most valuable feature of this solution."

"It has always been a stable solution."

"The Elastic User Interface framework lets us do custom development when needed. You need to have some Javascript knowledge. We need that knowledge to develop new custom tests."

"The solution is open-source and helps with back-end logging. It is also easy to handle."

"The solution allows us to dig deep into data."

"Elastic Observability significantly improves incident response time by providing quick access to logs and data across various sources. For instance, searching for specific keywords in logs spanning over a month from multiple data sources can be completed within seconds."

"The price is very less expensive compared to the other solutions."

More Elastic Observability pros

"We use Security Onion for internal vulnerability assessment."

"Security Onion is the most mature solution in the market."

"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."

Cons

"There's a steep learning curve if you've never used this solution before."

"It lacked some capabilities when handling on-prem devices, like network observability, package flow analysis, and device performance data on the infrastructure side."

"Elastic Observability needs to improve the retrieval of logs and metrics from all the instances."

"Elastic Observability’s price could be improved."

"The price is the only issue in the solution. It can be made better and cheaper."

"Elastic Observability is reactive rather than proactive. It should act as an ITSM tool and be able to create tickets and alerts on Jira."

"One example is the inability to monitor very old databases with the newest version."

"The cost must be made more transparent."

More Elastic Observability cons

"Security Onion's user interface could be improved."

"The initial setup of the solution is a little bit difficult."

"The product is not easy to learn."

Pricing and Cost Advice

"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 is cheaper than other similar solutions, such as Dynatrace. Its license calculation is based on various factors like data volume and physical infrastructure, particularly related to RAM capacity."

"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 have been using the open-source version."

"We will buy a premium license after POC."

"Elastic Observability's pricing could be better for small-scale users."

"Pricing is one of those situations where the more you use it, the more you pay."

"One needs to pay for the licenses, and it is an annual subscription model right now."
