Embedded Resource Manager

---

The Embedded Resource Manager (ERM) feature allows you to monitor internal system resource utilization for specific resources such as the buffer, memory, and CPU. ERM monitors resource utilization from the perspective of various subsystems within the Cisco IOS software such as resource owners (ROs) and resource users (RUs). ERM allows you to configure threshold values for system resources.

The ERM infrastructure is designed to be extensible and to allow for granular monitoring on an IOS task basis. Network administrators can define thresholds to create notifications according to the real-time resource consumption. ERM goes beyond simply monitoring for total CPU utilization. Through the use of ERM, network administrators and operators can gain a better understanding of the device's operational characteristics, leading to better insight into system scalability and improved system availability.
