Ranger Dashboard

Pulse provides charts to monitor the health and performance of Ranger Admin and User Sync services. These charts track key metrics such as CPU usage, JVM memory, HTTP requests, thread activity, and garbage collection patterns—helping you detect service strain, memory issues, and API failures early for smoother operations.

Charts

Chart	Description
Ranger Admin CPU Usage	Shows the percentage of CPU resources consumed by the Ranger Admin process. Useful for identifying performance bottlenecks and system strain.
Ranger Admin CPU Usage Aggregate	Displays the total CPU usage across all instances of Ranger Admin. Helps monitor overall resource utilization across the cluster.
Ranger Admin HTTP Request Count	Tracks the number of HTTP requests received by the Ranger Admin server. Helps you analyze API load and usage patterns.
Ranger Admin HTTP Request Error Count	Shows the total number of failed HTTP requests. Helps detect errors in API communication and service disruptions.
Ranger Admin JVM Memory	Displays the amount of JVM memory used by the Ranger Admin process. Useful for analyzing memory efficiency and diagnosing memory leaks.
Ranger Admin Thread Pool	Shows the count of active and idle threads in the Ranger Admin thread pool. Helps monitor service responsiveness and potential thread exhaustion.
Ranger User Sync CPU Usage	Displays the percentage of CPU used by the Ranger User Sync service. Helps ensure resource consumption is within expected limits.
Ranger User Sync JVM Memory	Shows the JVM memory usage for the Ranger User Sync service. Helps diagnose memory issues affecting sync performance.
Ranger Admin GC Collection Count	Indicates the total number of garbage collection (GC) events in the Ranger Admin JVM. Frequent GC events may point to memory pressure.
Ranger Admin GC Collection Time	Displays the total time spent on GC operations in the Ranger Admin JVM. Helps assess JVM efficiency and potential slowdowns.
Ranger User Sync GC Time	Shows the cumulative time spent on garbage collection by the Ranger User Sync JVM. Useful for analyzing memory cleanup performance.
Ranger User Sync GC Count	Displays the number of GC events in the Ranger User Sync JVM. Helps detect patterns in memory usage and application load.
