Amazon CloudWatch vs Logstash: What are the differences?
What is Amazon CloudWatch? Monitor AWS resources and custom metrics generated by your applications and services. With Amazon CloudWatch, you gain system-wide visibility into resource utilization, application performance, and operational health. Programmatically retrieve your monitoring data, view graphs, and set alarms to help you troubleshoot, spot trends, and take automated action based on the state of your cloud environment.
What is Logstash? Collect, Parse, & Enrich Data. Logstash is a tool for managing events and logs. You can use it to collect logs, parse them, and store them for later use (like, for searching). If you store them in Elasticsearch, you can view and analyze them with Kibana.
Amazon CloudWatch and Logstash are primarily classified as "Cloud Monitoring" and "Log Management" tools respectively.
Some of the features offered by Amazon CloudWatch are:
- Basic Monitoring for Amazon EC2 instances: ten pre-selected metrics at five-minute frequency, free of charge.
- Detailed Monitoring for Amazon EC2 instances: seven pre-selected metrics at one-minute frequency, for an additional charge.
- Amazon EBS volumes: eight pre-selected metrics at five-minute frequency, free of charge.
On the other hand, Logstash provides the following key features:
- Centralize data processing of all types
- Normalize varying schema and formats
- Quickly extend to custom log formats
"Monitor aws resources" is the primary reason why developers consider Amazon CloudWatch over the competitors, whereas "Free" was stated as the key factor in picking Logstash.
Logstash is an open source tool with 10.3K GitHub stars and 2.76K GitHub forks. Here's a link to Logstash's open source repository on GitHub.
According to the StackShare community, Amazon CloudWatch has a broader approval, being mentioned in 706 company stacks & 321 developers stacks; compared to Logstash, which is listed in 550 company stacks and 270 developer stacks.

If you have a single server, checking log files is as easy as SSHing to it and viewing logs. When you move to the container world, with many servers, you need a place to aggregate and search through all of your logs. CloudWatch provides us with this and it was trivial to setup.
CloudWatch is “on by default” in Amazon. And by just configuring a few alarms you can have a near-zero-cost monitoring service of your own.
- Collect metrics for Grafana.
- Alerts for AutoScale.
- Centralized-logging: rds, ec2, app logs with CloudWatch Log
