Disk Space Monitoring on EC2 Instances

•Use Case: Monitor disk usage on EC2 instances and trigger alerts when usage exceeds thresholds.

•Integrate with CloudWatch to monitor disk space usage.

•Automatically trigger cleanup scripts or scale up disk space when thresholds are exceeded.

Health check for a host
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.
This task performs some basic health checks on a host. Three important things to check for any host is its CPU, memory, and disk space. While there are basic commands to check each of these, the following runbook processes the outputs of those commands and extract the relevant information to see if this host needs attention.
