Overall Satisfaction with Amazon CloudWatch

Use Cases and Deployment Scope

We use Amazon CloudWatch for monitoring cloud and deriving the lot of useful metrics. We have deployed applications with micro-service architecture and observe them for CPU usage, Network usage and Disk usage with help of CloudWatch default Dashboard. We have also created custom dashboards observe certain exceptions. All the deployments which we have done on AWS, CloudWatch is the one which is used for sure. It also helps us to trigger the alarm when billing goes up than a standard limit.

Pros and Cons

Pros

It provides lot many out of the box dashboard to observe the health and usage of your cloud deployments. Few examples are CPU usage, Disk read/write, Network in/out etc.
It is possible to stream CloudWatch log data to Amazon Elasticsearch to process them almost real time.
If you have setup your code pipeline and wants to see the status, CloudWatch really helps. It can trigger lambda function when certain cloudWatch event happens and lambda can store the data to S3 or Athena which Quicksight can represent.

Cons

Sometimes live metrics show older data and take time to refresh. It fills dashboard with stale data.
There is no provision of Webhooks. You must need to go via the route of Amazon Lambda. They should provide the way to integrate custom webhooks.
This service is bit costly.
