Review summaries and opinions

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

ROI

Sentiment score
6.9
Amazon CloudWatch offers cost savings and control, aiding compliance but challenges remain in quantifying returns during cloud migrations.
Sentiment score
6.9
Splunk AppDynamics boosts productivity, software quality, and cost savings by enhancing performance monitoring and expediting issue resolution.
Amazon CloudWatch offers cost-saving advantages by being an inbuilt solution that requires no separate setup or maintenance for monitoring tasks.
According to errors, exceptions, and code-level details related to their application performance on a daily basis, the application development team tries to help with Splunk AppDynamics to reduce errors and exceptions, which helps the end users get application availability and feel more confident.
To understand the magnitude of it, when the company asked to replace Splunk AppDynamics with another tool, I indicated that for the proposed tool, we would need five people to do the analysis that Splunk AppDynamics enables me to do.
It's very hard to find ROI because we are currently focused only on the on-premises applications.
 

Customer Service

Sentiment score
7.4
Amazon CloudWatch support is generally praised for responsiveness and expertise, though experiences and costs vary by support package.
Sentiment score
7.3
Splunk AppDynamics' customer service is praised for responsiveness and expertise, though some users note occasional response delays.
In recent years, due to business expansion, knowledge levels among support engineers seem to vary.
While using their cloud and cloud resources, if you have an issue with CloudWatch, you must pay additional monthly fees to get time from dedicated tech support.
AppDynamics is much more helpful.
We got a contact, an account manager, to work directly with for technical support.
They help us resolve any issues raised by our team relating to operations, application instrumentation, or any other issues.
 

Scalability Issues

Sentiment score
7.7
Amazon CloudWatch is praised for its scalability, managing large workloads effortlessly and adapting to diverse performance monitoring needs.
Sentiment score
7.4
Splunk AppDynamics is adaptable and scalable, praised for performance and configuration, though some face challenges with large-scale deployments.
Amazon CloudWatch's scalability is managed by AWS.
We have reached maximum capacity in our tier, and extending capacity has not been cost-effective from Splunk's perspective.
I would rate the scalability of Splunk AppDynamics as a nine out of ten.
I assess how Splunk AppDynamics scales with the growing needs of my organization as good, since we are growing and adding more servers.
 

Stability Issues

Sentiment score
8.1
Amazon CloudWatch is reliable and stable, though users experience occasional logging delays and minor complexities in query customization.
Sentiment score
7.7
Splunk AppDynamics is generally stable and reliable, with occasional minor issues, improved by regular updates for effective monitoring.
I sometimes notice slowness when Amazon CloudWatch agents are installed on machines with less capacity, causing me to use other monitoring tools.
It is necessary to conduct appropriate testing before deploying them in production to prevent potential outages.
There are no issues or bugs with the 20.4 version; it is very stable with no functionality or operational issues.
I can rate it nine out of ten.
 

Room For Improvement

Amazon CloudWatch needs enhancements in customization, log management, pricing, integrations, data visibility, and user interface for better performance.
Users find Splunk AppDynamics challenging due to complexity, poor integration, limited support, outdated features, and prohibitive pricing.
When using third-party dashboards such as Kibana or Grafana and other visualization tools, there should be a way to feed CloudWatch's data and logging capabilities into these visualization tools.
Maybe Amazon Web Services can improve by providing a library for CloudWatch with some useful features.
Amazon CloudWatch charges extra for custom metrics, which is a significant disadvantage.
Splunk AppDynamics does not support the complete MELT framework, which includes metrics, events, logging, and tracing for the entire stack.
If AppDynamics could develop a means to monitor without an agent, it could significantly improve application performance and reduce potential problems.
A good integration with Splunk would be very interesting, as Splunk is a good product for logs, and that part is currently missing in Splunk AppDynamics.
 

Setup Cost

Amazon CloudWatch pricing is usage-based, often cost-effective, but may increase with data use and custom metrics.
Enterprise buyers of Splunk AppDynamics should anticipate higher costs and consider pricing options, licensing, and negotiation for cost efficiency.
Overall, the pricing of Amazon CloudWatch is very expensive.
Amazon CloudWatch charges more for custom metrics as well as for changes in the timeline.
We completed a three-year deal for Splunk and for AppDynamics, which costs millions of dollars.
Customers have to pay a premium price, however, they receive considerable value from the product.
All these solutions at the moment are cheap, but it is like paying for insurance; you pay insurance to avoid major damage.
 

Valuable Features

Amazon CloudWatch offers metrics, alerts, automation, and analytics with seamless AWS integration, scalability, and third-party service support.
Splunk AppDynamics offers user-friendly real-time monitoring, deep analysis, and integration for performance insights and proactive diagnostics.
Amazon CloudWatch allows me to set up and view even historical logs, which is one of the features I find valuable.
I like its filtering capability and its ability to give the cyber engine insights.
The best features of Amazon CloudWatch need to improve visibility into the network because when using hundreds of network resources such as transit gateway, VPNs, routers, route tables, and firewalls, it does not give many details in a structured manner.
We have multiple tools, but end users prefer to use Splunk AppDynamics because their portal navigation is very simple and clear.
The real user monitoring and digital experience monitoring effectively track actual user experience with the applications, including page loading, interaction time for both desktop and mobile applications.
The feature that I appreciate in AppDynamics Browser Real-User Monitoring is the intuitive and user-friendly dynamic mapping it creates for workflows.

Rahul Kundu - PeerSpot reviewer
Proactively address issues with seamless monitoring while enhancing custom metrics functionality
We use CloudWatch for monitoring and logging. It helps us monitor our applications' performance, particularly in ensuring that every API hit returns a response within four seconds, which is our SLA. We also monitor invocation errors in Lambda and use CloudWatch alerts to notify us of any issues…
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.
