Azam S M - PeerSpot reviewer
Infrastructure Lead at Danat Fz LLC
Has provided reliable monitoring and alerting through extensive metric tracking and dashboard configuration
Amazon CloudWatch itself provides a lot of data. However, for visualization, we need to use third-party tools. We are in a process of integrating Grafana, Loki, and Prometheus to have better visualization on Amazon CloudWatch. We are also integrating Grafana with the application itself to get the application data and logs. Alternatively, there is AWS Kinesis and Glue where you can scrape the logs and have visualization, but a more easy option is Grafana. If you want to get a proper visual representation to see what is happening, then you need to integrate a third-party tool. Amazon CloudWatch has all the data, but to see what is happening, you need some third-party tool.

A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"You can enable alarms and metrics, and it has robust integration with AWS services. You can also trigger events. For example, if the CPU utilization is above 80%, it can launch a new instance for you."
"It is very easy to use; as a monitoring tool, whenever your system experiences issues, it will notify you and is directly linked to your service."
"We can set CPU thresholds using the solution."
"It offers direct integrations with various storage providers, making it convenient to push logs from CloudWatch to these external platforms."
"What I found most valuable in Amazon CloudWatch is that it gives you detailed information, which I found helpful because it can even provide you with data for the past one minute, which is quite granular. That was what helped me most in terms of finding the root causes. Task automation is another valuable feature of Amazon CloudWatch."
"The most valuable feature of Amazon CloudWatch is collecting the logs from Lambda."
"The most valuable part is the metrics part, which is really good."
"The monitoring feature is valuable."
"Security Onion is the most mature solution in the market."

"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"The solution's integration could be easier for laypersons."
"Maybe Amazon Web Services can improve by providing a library for CloudWatch with some useful features."
"Better reporting is always something needed. That could be an answer to just about anything. But you always want better reporting, better dashboards, things that are just more dynamic and more accessible."
"Adding conditional expressions would enhance its functionality."
"I do not know whether or not CloudWatch can be integrated with on-prem services."
"The product's configuration has some challenges. The solution needs to be more user-friendly."
