High memory usage-juniper-junos

Vendor: juniper

OS: junos

Description:
Indeni will alert if the memory utilization of a device is above a high threshold. If the device has multiple memory elements, each will be inspected separately and alert for.

Remediation Steps:
Determine the cause for the high memory usage of the listed elements.

How does this work?
This script run the “show chassis routing-engine node X” command via SSH connection to retrieve the memory usage for both Control and Data plane.

Why is this important?
The various memory components are important to ensure smooth operation. They include Control and Data plane memory usage.

Without Indeni how would you find this?
An administrator needs to log in the device to run the “show chassis routing-engine node X” command to retrieve memory usage for Control and Data plane.

        why: |
            Control and data plane CPU utilization is important to track to ensure smooth operation. A high CPU utilization of the control plane may impact the management interface, while a high CPU utilization in the data plane may impact traffic handling.
