HOST-RESOURCES-MIB provides information for host computer resources. Use this MIB to monitor CPU and memory usage statistics. For example, checking the current CPU load (hrProcessorLoad object) can help you troubleshoot performance issues on the firewall.
Palo Alto Networks firewalls, Panorama, and WF-500 appliances support portions of the following object groups:
Object Group
Provides information such as CPU load, storage capacity, and partition size. The hrProcessorLoad OIDs provide an average of the cores that process packets. For the PA-5260 firewall, which has multiple dataplanes (DPs), the average is of the cores across the three DPs that process packets.
Provides information such as system uptime, number of current user sessions, and number of current processes.
Provides information such as the amount of used storage.
RFC 2790 defines this MIB.
