Adelina Craciun - PeerSpot reviewer
Customization enables tailored monitoring and alerting across departments
The possibility to customize it has been quite useful. Whatever the other departments want to dream up, we implement. Whatever they want to monitor, the granularity of it, the changes in the threshold, and the anomalies that they want reported all require some development. So far, every single request has been fulfilled.
SI
A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Quotes from Members

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

Pros

"I recommend Elastic Observability for its completeness of vision and wide ecosystem."
"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."
"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."
"The most valuable feature of Elastic Observability is the text search."
"I think Elastic Observability is already in very good shape."
"It is scalable and supports multitenancy, which is beneficial for MSPs."
"It has always been a stable solution."
"The product has connectors to many services."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"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."
 

Cons

"One example is the inability to monitor very old databases with the newest version."
"More web features could be added to the product."
"Elastic Observability is an excellent product for monitoring and visibility, but it lacks predictive analytics. Most solutions are aligned with the AIOps requirements, but this piece is missing in Elastic and should be included."
"They need more skills in the market. There are not enough skills in the market. It is not pervasive enough on the market, in my opinion. In other words, there isn't a big enough user base."
"Elastic Observability needs to improve the retrieval of logs and metrics from all the instances."
"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."
"The only challenging aspect for new users is often writing the query language."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"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."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
 

Pricing and Cost Advice

"One needs to pay for the licenses, and it is an annual subscription model right now."
"Pricing is one of those situations where the more you use it, the more you pay."
"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."
"Elastic Observability's pricing could be better for small-scale users."
"The product’s pricing needs improvement."
"The product is not that cheap."
"We have been using the open-source version."
"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."
"The pricing is quite reasonable, especially when compared to the broader market."
