Web management console dashboard data plane CPU percentage not being updated
12100

Symptom
- Upon upgrading PA-3220, PA-3250 and PA-3260 to PAN-OS 8.1.14, Data Plane CPU percentage on web management console dashboard would appear not being updated
- Logging onto Firewall's command-line interface and checking the same reading through system state (command "show system state | match sys.monitor.s1.dp0.exports") would see the percentage is updated approx. once a minute, e.g.:
> show clock
Mon Jun 15 10:10:00 CDT 2020
> show system state | match sys.monitor.s1.dp0.exports
sys.monitor.s1.dp0.exports: { 'cpu': { '1minavg': 20, }, 'slot': 1, }
> show clock
Mon Jun 15 10:15:00 CDT 2020
> show system state | match sys.monitor.s1.dp0.exports
sys.monitor.s1.dp0.exports: { 'cpu': { '1minavg': 26, }, 'slot': 1, }
> show clock
Mon Jun 15 10:20:00 CDT 2020
> show system state | match sys.monitor.s1.dp0.exports
sys.monitor.s1.dp0.exports: { 'cpu': { '1minavg': 29, }, 'slot': 1, }
- The data plane performance statistics stop being recorded into data plane monitor log periodically moment after system is up
Environment
- Palo Alto Firewalls PA-3220, PA-3250 and PA-3260
- PAN-OS 8.1.14
Cause
In PAN-OS 8.1.14, an additional data plane debug data is added into periodic data plane performance statistics collection (PAN-140270). Such change exposed another problem with resource utilization for process sysd, causing certain performance statistics not being recorded correctly.
Resolution
A fix for the problem is to be released in PAN-OS 8.1.15.
