Feature Introduction

Supports online GC analysis for Java processes by collecting, recording, and analyzing GC logs in real time, helping users identify whether process exceptions are caused by GC.
GC view: Filter by service, role, node, and time to view the related GC distribution and point information.
GC list: Filter GC log data as needed to view multidimensional GC information.

Directions

1. Log in to the EMR console and click the corresponding Cluster ID/Name in the cluster list to enter the cluster details page.
2. On the cluster details page, click Cluster Monitoring, and then select JAVA Analysis > GC Online Analysis to view the GC view and point information.
3. Additionally, the GC query list information is provided, with some column headers supporting filtering or sorting operations. The services and roles that support GC log collection are as follows:
