AWS CloudWatch Monitoring

A reference skill for CloudWatch metrics, logs, alarms and dashboards with ready-to-run CLI and boto3 examples.

Data & AnalyticsIntermediate★ 1,150⑂ 444AI score 8/10Last updated: Aug 24, 2026

What it does

  • Summarizes CloudWatch core concepts (metrics, namespaces, dimensions, log groups/streams, alarm states) so the assistant uses precise terminology.
  • Ships copy-paste patterns for metric alarms, Lambda error-rate math alarms, Logs Insights queries, metric filters, custom metric publishing, and dashboard creation in both AWS CLI and boto3.
  • Includes a troubleshooting section for missing metrics, alarms stuck in INSUFFICIENT_DATA, logs not appearing, and cost spikes, each with a diagnostic command.
  • Lists operational and cost best practices: retention policies, avoiding dimension explosion, anomaly detection, subscription filters.

Who it's for

  • Backend, DevOps and SRE engineers who configure monitoring on AWS themselves.
  • Developers debugging Lambda or EC2 issues through log queries.
  • Teams auditing and reducing a growing CloudWatch bill.

Examples

  1. "Alarm me via SNS when this EC2 instance goes over 80% CPU" → generates the exact put-metric-alarm call.
  2. "Show ERROR lines from the last hour of my Lambda logs" → uses start-query plus get-query-results.
  3. "Build a dashboard with Lambda invocations and recent errors" → writes dashboard.json and runs put-dashboard.

Install the skill I found on Claude Skill Mart.
Copy the skills/cloudwatch folder from the GitHub repo itsmostafa/aws-agent-skills into my ~/.claude/skills/cloudwatch/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/itsmostafa/aws-agent-skills.git /tmp/aws-agent-skills && mkdir -p ~/.claude/skills && cp -r /tmp/aws-agent-skills/skills/cloudwatch ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Prerequisites: install the AWS CLI and configure credentials with aws configure (run pip install boto3 if you plan to use the Python snippets).
  2. Clone the repository: git clone https://github.com/itsmostafa/aws-agent-skills.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy just this skill: cp -r aws-agent-skills/skills/cloudwatch ~/.claude/skills/
  5. Restart Claude Code and ask something like "create a CloudWatch alarm for my Lambda errors" to trigger it.
  6. Review any generated command before running it against a production account, or test in a sandbox account first.
