Resourcefulness and problem solving
Monitoring tools do a great job of telling you what is going on in your cluster, and they can often point out if there is a problem. However, these tools won't give you a recipe for how to actually fix a problem. Resolving issues takes critical thinking, attention to detail, and persistence. Some of the problem-solving themes this book talks about are as follows:
- Always try to recreate the problem
- Be on the lookout for configuration and user errors
- Only make one configuration change at a time before testing
This book also provides some real-world case studies that help you turn the information provided by monitoring tools into insights to resolve Elasticsearch issues.
