Usage notes

By default, the health check feature for Hadoop clusters does not include daily cluster report analysis. To view this analysis, you must enable EMR Doctor. For more information, see Enable EMR Doctor for Hadoop clusters.

View reports

1. Go to the monitoring and diagnostics page.

   1. Log on to the E-MapReduce console.

   2. In the top navigation bar, select a region and a resource group based on your requirements.

2. Click the Daily Cluster Reports tab to view a list of all health diagnostic reports for the cluster.

   In the Daily Cluster Reports section, the Health Status column displays the health score of the cluster. The following table describes the health status that corresponds to each score range.

   Health status	Description
   0 <= x <= 60	The cluster is unhealthy. Take corrective actions immediately.
   60 < x <= 80	The cluster is in a suboptimal state. Optimization is recommended.
   80 < x <= 100	The cluster is healthy. No action is required.

   Note

   Cluster health is scored on a scale of 0 to 100.

3. View report details.

   In the Actions column, click View Report to view the cluster's detailed diagnostic information.

   This page provides an overview of the cluster's health status and basic report information, such as the health score, cluster ID, report ID, and diagnosis time. The report overview, which varies by cluster type, displays diagnostic items and a summary analysis that highlights key issues. For detailed problem analysis, see the analysis of specific diagnostic items in the following sections.
