# Runbook Catalog

Automate cost-saving actions across your cloud environment using predefined Runbooks in OneLens. Each Runbook targets a specific saving opportunity and executes a streamlined remediation workflow. These automated workflows eliminate manual overhead and drive consistent cost optimization.

The current Runbook Catalog covers AWS resources. *Runbooks for Azure, GCP, and OCI resources are planned for future releases.*

## Available Runbooks

OneLens provides a growing catalog of Runbooks, including:

1. [Delete CloudWatch Alarms in Insufficient State](/automate/remediations/runbooks/runbook-catalog/delete-cloudwatch-alarms-in-insufficient-state.md)
2. [Delete EBS Snapshots for Unused Volumes](/automate/remediations/runbooks/runbook-catalog/delete-ebs-snapshots-for-which-corresponding-volumes-are-not-in-use.md)
3. [Delete Idle ElastiCache/Memcached Clusters](/automate/remediations/runbooks/runbook-catalog/delete-idle-elasticache-memcached-cluster.md)
4. [Delete RDS Snapshots Older Than a Specified Period](/automate/remediations/runbooks/runbook-catalog/delete-rds-snapshots-older-than-a-specified-period-of-time.md)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.onelens.cloud/automate/remediations/runbooks/runbook-catalog.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
