Johnny Suleiman - PeerSpot reviewer
Scalability is a key feature as it allows easy scaling of the platform without downtime
OpenSearch is used as a search engine for specific logs, mainly in e-commerce and monitoring the logs themselves. It is very valuable for e-commerce, enabling data analysis on application logs and customer behavior, and can be integrated with other services, including AI and machine learning…
Gyanesh Rahatekar - PeerSpot reviewer
Application performance management and error resolution improved with data-driven insights
Dynatrace has multiple functions compared to Splunk AppDynamics, so Splunk AppDynamics should add those functions, which are not available as of now. Dynatrace has a universal agent that collects all information related to their CI, and if one CI has multiple languages, then there is no need to instrument multiple agents. However, Splunk AppDynamics requires multiple agents; if I have one server with multiple applications in different languages, then I need to instrument different agents for each application. Splunk AppDynamics should work with Dynatrace with one single universal agent that works with all application languages, eliminating the need for multiple implementations.

Quotes from Members

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

Pros

"This service already sorts data like vectors. They have classified the storage pre-defined."
"The initial set up is very easy...We really appreciate Amazon!"
"It enables us to efficiently search and retrieve our event data, offering us a versatile approach to locate specific information within these logs."
"The most valuable features of Amazon Elasticsearch are ease of use, native JSON, and efficiency. Additionally, handles many use cases and search grammar was useful."
"Regarding valuable features of the solution, we found with the process, which we have used in both cases where we used the solution that while you're seeing the streaming of data, you can analyze in the initial phase what sort of data you are streaming and whether it is valuable."
"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."
"The business analytics capabilities are the most important feature it provides."
"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."
"Visibility to the end-users is a valuable feature."
"AppDynamics Database Monitoring's dashboarding is its best feature."
"The features of Splunk AppDynamics that I prefer most are the monitoring aspect, making sure we can drill down and find problems."
"The solution offers great visibility that allows you to track where errors originated."
"The most valuable aspect of the solution is the ability to discover and track transactions."
"We're a large organization, so we appreciate AppDynamics' wide coverage. It may not work in all areas, but it has broad coverage. We can use the same dataset for different use case aspects. That is the beauty of AppDynamics. You can coordinate APM, EUM, and infrastructure through one dataset."
"This solution not only provides answers but also provides sensor data. This allows us to quickly resolve issues that developers may take a long time to solve."
"Before we moved the code to AppDynamics, we had to compare the agile process and also had to make sure that they're following the standards."
 

Cons

"The price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."
"We faced documentation challenges during integration after migrating from Elasticsearch to Amazon OpenSearch Service. Better documentation on integration, query handling, and a more user-friendly UI could enhance the product."
"It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users."
"They can enhance data visualization."
"One improvement I would like to see is support for auto-scaling."
"There is a problem with the database. Amazon only provides the hosting to run our applications bias, but there is no option to manage the database within the Elasticsearch product."
"In terms of data handling capabilities with Amazon OpenSearch Service, they can be complex and managing data in comparison to other SIM solutions is a major drawback, as it is very hard to handle the data."
"One glaring issue was with our mapping configuration as the system accepted the data we posted, but after a few months, when we attempted complex queries, we realized the date formatting had become problematic."
"I install it frequently and sometimes when they fix something they break something else, so better QA is needed to ensure the quality of their fixes."
"An area that has room for improvement on the CR and ERP would be the addition of monitoring of the internal solution. For example, you can monitor the day-to-day and everything in the transactions with AppDynamics, but there's also a lot going on in the kernel itself that you cannot monitor. The automation needs to improve as well. As it stands, a lot of customization needs to happen before you can use AppDynamics."
"If AppDynamics could do a one-agent function with their actual monitoring effectiveness, it will be the greatest tool."
"The Log Analytics feature is a bit complicated."
"Splunk AppDynamics does not support the complete MELT framework, which includes metrics, events, logging, and tracing for the entire stack. It lacks maturity in correlation within the observability spectrum."
"The discovery is acceptable, however, users need to configure many things if they want good discovery."
"They could align the product strategy to evolve as a complete solution."
"The solution could be more mobile friendly."
 

Pricing and Cost Advice

"The solution is not expensive, but priced averagely, I will say."
"Compared to other cloud platforms, it is manageable and not very expensive."
"You only pay for what you use."
"There is a community edition available and the price of the commercial offering is reasonable."
"AppDynamics is what I would consider an enterprise-level solution. This means that it's a solution that is intended for use by larger organizations, while small or medium-sized businesses may find it difficult to afford. The number of agents required will also impact the pricing, and smaller companies may only be able to afford a limited number of agents. Essentially, the cost of the solution is not within the reach of every organization, and only some may be able to afford it."
"Take into consideration what you get for specific pricing models and how much it costs to add on things you may need later.​"
"You are required to purchase licenses whether you use it or not. It is not pay-as-you-use."
"Pricing is based on the size of the deployment."
"It is a more expensive APM among the competitors, which is fine because it also does a lot more on the auto-detection and the AI side... It is not a cheap product. None of them are. The price is fair, but I could use it on more projects if they had a lower price."
"The price of AppDynamics could be reduced in my region."
"AppDynamics Server Monitoring is a very expensive product, but if you negotiate well, you get value for money...My company used to make early payments toward the licensing costs of the solution, but now my company has opted for a different licensing model."
"My understanding is that the price of this solution is quite high, compared to other products."
