Configure Hardware Threshold Monitoring for Capacity Planning
SUMMARY This
This topic describes hardware threshold monitoring, how to configure a resource list to poll date and display hardware resource utilization, and the operational commands you can use to monitor utilization.
Hardware Threshold Monitoring
To configure hardware threshold monitoring, create a resource list and specify which hardware resources to monitor or monitor all your hardware resources. You can choose several options to enhance resource lists. You can specify a polling interval for how often hardware resource data is polled, configure an upper and lower threshold boundary and, when a boundary is breached, receive notification. You can also configure a monitor profile with these optional settings that can be applied to your resource lists.
Configure a Resource List to Monitor Resources
Create a resource list to monitor hardware resources.
You can configure multiple resource lists, but the same resource can only be used once and cannot be duplicated on multiple resource lists.
Once configured, hardware resource utilization data is periodically polled. The default lower and upper threshold utilization is 50% and 90%, respectively.
To configure a resource list with all resources:

Monitor Utlilization
View the monitored data using operational mode commands or use Junos Telemetry interface (JTI) to send data from your device to a collector using the resource path /junos/system/linecard/npu/memory/.
Use the show system packet-forwarding-options
hw-resource-utilization-info
command to show the maximum capacity
and current utilization for all the applicable resources.
Use the show system packet-forwarding-options hw-resource-monitor
utilization-info
command to display hardware resource utilization,
resource health, upper and lower threshold boundaries, and the maximum capacity
for each resource.
Use the show system packet-forwarding-options hw-resource-monitor
resource-list
command to display the hardware resources contained
in a resource list and the associated monitor profile (if configured).
If you configure an optional monitor profile, use the show system
packet-forwarding-options hw-resource-monitor monitor-profile
command to display the configured upper and lower threshold values set as the
boundary for a hardware resource and the notification type to be issued when a
resource's utilization rate crosses a threshold boundary.
