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.

Quotes from Members

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

Pros

"Elastic Observability is highly stable; we ingested nearly 170 million records in the system and we have tested it, and you get your reports and dashboards within a few seconds, so it doesn't take much time."

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

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

"It's easy to deploy, and it's very flexible."

"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."

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

"The architecture and system's stability are simple."

More Elastic Observability pros

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

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

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

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

Cons

"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 APM's visualization is not that great compared to other tools. It's number of metrics is very low."

"The cost must be made more transparent."

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

"Elastic Observability’s price could be improved."

"The solution would be better if it was capable of more automation, especially in a monitoring capacity or for the response to abnormalities."

"I am familiar with Azure Monitor, which I find more user-friendly compared to Elastic, which is a very technical tool."

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

More Elastic Observability cons

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

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

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

"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."

Pricing and Cost Advice

"The product is not that cheap."

"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."

"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."

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

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

"We will buy a premium license after POC."

"The price of Elastic Observability is expensive."

More Elastic Observability pricing and cost advice

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