Captures data from all other sources and becomes a MOM aka monitoring of monitors
Scalability and ROI are the areas they have to improve. Their license terms are based on the number of cores. If you increase the number of cores, it becomes very difficult to manage at a large scale. For example, if I have a $3 million project, I won't sell it because if we're dealing with a 10 TB or 50 TB system, there are a lot of systems and applications to monitor, and I have to make an MOM (Mean of Max) for everything. This is because of the cost impact. Also, when you have horizontal scaling, it's like a multi-story building with only one elevator. You have to run around, and it's not efficient. Even the smallest task becomes difficult. That's the problem with horizontal scaling. They need to improve this because if they increase the cores and adjust the licensing accordingly, it would make more sense.

Provides quick query search and has a big database
I did not face any issues integrating Faiss with other tools. I would recommend the solution to other users. Faiss has facilitated my AI-driven project very well. I recommend that other users use it for their AI projects because it provides quick query search and has a big database. Overall, I rate the solution nine and a half out of ten.

Quotes from Members

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

Pros

"The solution has good security features. I have been happy with the dashboards and interface."
"A nonstructured database that can manage large amounts of nonstructured data."
"Gives us a more user-friendly, centralized solution (for those who just needed a quick glance, without being masters of sed and awk) as well as the ability to implement various mechanisms for machine-learning from our logs, and sending alerts for anomalies."
"It's a stable solution and we have not had any issues."
"The search speed is most valuable and important."
"Implementing the main requirements regarding my support portal​."
"The most valuable feature of Elastic Enterprise Search is the opportunity to search behind and between different logs."
"The initial installation and setup were straightforward."
"I used Faiss as a basic database."
"The product has better performance and stability compared to one of its competitors."
 

Cons

"Enterprise scaling of what have been essentially separate, free open source software (FOSS) products has been a challenge, but the folks at Elastic have published new add-ons (X-Pack and ECE) to help large companies grow ELK to required scales."
"It needs email notification, similar to what Logentries has. Because of the notification issue, we moved to Logentries, as it provides a simple way to receive notification whenever a server encounters an error or unexpected conditions (which we have defined using RegEx​)."
"Improving machine learning capabilities would be beneficial."
"Performance improvement could come from skipping background refresh on search idle shards (which is already being addressed in the upcoming seventh version)."
"Scalability and ROI are the areas they have to improve."
"Better dashboards or a better configuration system would be very good."
"We see the need for some improvements with Elasticsearch. We would like the Elasticsearch package to include training lessons for our staff."
"It is hard to learn and understand because it is a very big platform. This is the main reason why we still have nothing in production. We have to learn some things before we get there."
"It would be beneficial if I could set a parameter and see different query mechanisms being run."
"It could be more accessible for handling larger data sets."
 

Pricing and Cost Advice

"The solution is not expensive because users have the option of choosing the managed or the subscription model."
"We are using the open-sourced version."
"The price could be better."
"The solution is affordable."
"The basic license is free, but it comes with a lot of features that aren't free. With a gold license, we get active directory integration. With a platinum license, we get alerting."
"To access all the features available you require both the open source license and the production license."
"ELK has been considered as an alternative to Splunk to reduce licensing costs."
"​The pricing and license model are clear: node-based model."
"Faiss is an open-source solution."
"It is an open-source tool."
