Real-time dashboards and visual insights have streamlined issue analysis and monitoring

After careful consideration about areas for improvement in Elastic Observability, aspects such as pricing, customization, implementation, and scalability could be improved. As a user of the system, I know what it costs but am not directly involved in cost-benefit evaluations or maintenance, which is handled by another team. I develop the visual representation of the data and frankly, I don't see major gaps in my application or anything I would really miss; I appreciate the fast pace of the developments that have occurred in the last couple of years. Regarding room for improvement in Elastic Observability, I would have preferred built-in tools to manage the indexes on deployment for better visual representation, as the initial feedback regarding system performance and data storage was fairly primitive and lacking.

Quotes from Members

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

Pros

"Its diverse set of features available on the cloud is of significant importance."

"For full stack observability, Elastic is the best tool compared with any other tool like New Relic or AppDynamics or Dynatrace."

"From my experience with several major customers, the most valued feature of Elastic is its log analytics capabilities."

"It is a powerful tool that allows users to collect and transform logs as needed, enabling flexible visualization and analysis."

"I recommend Elastic Observability for its completeness of vision and wide ecosystem."

"Good design and easy to use once implemented."

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

"The very positive features are the cost effectiveness and the range of things that you can implement."

More Elastic Observability pros

"It's very easy to manage and monitor it."

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."

"Being open source lets us customize it for our monitoring needs, saving us money."

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

Cons

"Simplifying the parsing of logs and manual efforts would also be beneficial."

"I would have preferred built-in tools to manage the indexes on deployment for better visual representation, as the initial feedback regarding system performance and data storage was fairly primitive and lacking."

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

"Elastic Observability is difficult to use. There are only three options for customization but this can be difficult for our use case. We do not have other options to choose the metrics shown, such as CPU or memory usage."

"In the future, Elastic APM needs a portfolio iTool. They can provide an easy way to develop the custom UI for Kibana."

"More web features could be added to the product."

"The auto-discovery isn't nearly as good. That's a big portion of it. When you drop the agent onto the JVM and you're trying to figure things out, having to go through and manually do all that is cumbersome."

"Elastic Observability could improve asset discovery as the current requirement to push the agent is not ideal."

More Elastic Observability cons

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."

Pricing and Cost Advice

"We have been using the open-source version."

"The product is not that cheap."

"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."

"Users have to pay for some features, like the alerts on different channels, because they are unavailable in different source versions."

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

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

"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."

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

More Elastic Observability pricing and cost advice

"The pricing is quite reasonable, especially when compared to the broader market."
