# 4.3 Metrics

### Overview

Metrics dashboard provides a comprehensive overview of both system-level and realm-level performance metrics. Monitor **CPU Usage**, **Memory Utilization**, **Thread Activity**, and **Uptime** alongside realm metrics like **User** Count, **Group** Count, **Clients**, and **Active Sessions**. These insights help administrators track resource consumption, identify potential bottlenecks, and make informed decisions for performance tuning, scalability, and overall system health.

The Metrics page is located under the **Admin Console → Master Realm → Metrics** tab.\
This page is used to:

* **Real-Time Monitoring** – Continuously track live performance data across both **system** and **realm** levels. Metrics update dynamically, giving administrators immediate visibility into **CPU load**, **memory usage**, **thread activity,** and **user sessions** as they change in real time.
* **Comprehensive Coverage** – Gain a holistic view of system health through detailed metrics, including **CPU Usage**, **Memory Utilization**, **Thread Activity**, and **System Uptime**, alongside **realm-level insights** such as **User** Count, **Group** Count, **Clients**, and **Active Sessions**. This unified approach ensures complete visibility into both infrastructure and user activity.

* **Realm-Specific Visibility** – Monitor metrics at the realm level to understand user engagement and application usage patterns. View detailed statistics for **users**, **groups**, **clients**, and **active sessions** to assess realm performance, isolate issues, and ensure balanced resource distribution.
  * **Total Users Count (across all realms):**\
    Displays the cumulative number of users registered in all available realms. Useful for assessing overall user base size and system load.

  * **Total Clients Count (across all realms):**\
    Shows the combined total of all client applications registered across realms, helping track integration growth and application distribution.

  * **Total Groups Count (across all realms):**\
    Indicates the total number of user groups defined system-wide. This helps administrators evaluate the complexity of role and permission structures.

  * **Total Active Sessions Count (across all realms):**\
    Reflects the total number of active user sessions currently running across all realms. It provides real-time insight into concurrent user activity and helps in capacity planning.
