In Palo Alto Networks firewalls, the command show running resource-monitor minute is used to display real-time statistics and monitoring data related to various system resources on the firewall. This command provides a snapshot of resource utilization over the past minute, allowing administrators to assess the current load and performance of the device. Here’s how you can use this command:

Using the Command:

  1. Access the CLI:

    • Log in to the Palo Alto Networks firewall using SSH, Telnet, or the console cable.
  2. Enter Operational Mode:

    • Switch to operational mode by entering the following command:
      markdown

      > operational mode
      
  3. Execute the Command:

    • Use the show running resource-monitor minute command to display the minute-by-minute resource usage statistics:
      > show running resource-monitor minute
      

Output Interpretation:

When you execute this command, you typically see output similar to the following, which provides statistics for various system resources:

Resource Utilization (Resources: 1, Threshold: 85%, Time: 2023-06-15 14:27:10 UTC)
-----------------------------------------------------------------------------------
  Resource           Utilization (%)            Peak (5 min)            Peak Time
-----------------------------------------------------------------------------------
  CPU                  20.30                        30.10              14:24:23 UTC
  Memory               65.80                        70.20              14:24:23 UTC
  Session              48.30                        50.10              14:24:23 UTC
  Buffer               22.40                        25.60              14:24:23 UTC
  Session Tbl          35.50                        40.00              14:24:23 UTC
  Session Util         52.20                        55.00              14:24:23 UTC
  TCP Proxy            10.00                        12.00              14:24:23 UTC
  UDP Proxy            5.50                         7.20               14:24:23 UTC
  ICMP Proxy           1.20                         1.50               14:24:23 UTC
  DNS Proxy            2.50                         3.00               14:24:23 UTC

Explanation of Fields:

  • Resource: Specifies the type of resource being monitored (e.g., CPU, Memory, Sessions).
  • Utilization (%): Current utilization percentage of the resource.
  • Peak (5 min): Highest utilization observed within the last 5 minutes.
  • Peak Time: Time at which the peak utilization occurred.

Importance:

  • Real-time Monitoring: Helps administrators monitor the firewall's current load and performance.
  • Capacity Planning: Assists in identifying trends and potential issues before they impact operations.
  • Troubleshooting: Provides insights into resource bottlenecks during performance issues or abnormal traffic patterns.

By using show running resource-monitor minute, administrators can gain valuable insights into how effectively the firewall is handling its workload and whether any adjustments or optimizations are necessary to maintain optimal performance and security.
