resource-category jtree (Resource Monitor)


Hierarchy Level


Define the resource category that you want to monitor and analyze for ensuring system stability, especially the health and operating efficiency of I-chip-based line cards and Trio-based FPCs on MX Series routers. The resource category includes detailed CPU utilization, session rate, and session count statistics. You use the resource category statistics to understand the extent to which new attack objects or applications affect performance. The jtree memory on all MX Series router Packet Forwarding Engines has two segments: one segment primarily stores routing tables and related information, and the other segment primarily stores firewall-filter-related information. The Junos OS provides the memory-enhanced statement to reallocate the jtree memory for routes, firewall filters, and Layer 3 VPNs.



Specify the Jtree resource category for which you want to monitor the health (working condition), operating efficiency, traffic-handling capacity, and performance status.

The remaining statements are explained separately. See CLI Explorer.
