1.2.2 Introduction to Cluster Health Monitor

Cluster Health Monitor is a component of Oracle Grid Infrastructure, which continuously monitors and stores Oracle Clusterware and operating system resources metrics.

Enabled by default, Cluster Health Monitor:

• Assists node eviction analysis

• Logs all process data locally

• Enables you to define pinned processes

• Listens to CSS and GIPC events

• Categorizes processes by type

• Supports plug-in collectors such as traceroute, netstat, ping, and so on

• Provides CSV output for ease of analysis

Cluster Health Monitor serves as a data feed for other Oracle Autonomous Health Framework components such as Oracle Cluster Health Advisor and Oracle Database Quality of Service Management.
