Hi T0nyP,
Yes, it's possible with a custom alert in user_alert.conf, check this K article below :
https://support.f5.com/csp/article/K3667You can check the log message send in case of high CPU Usage in /etc/alertd/alert.conf
[root@f5Bigip:Active:In Sync] config # cat /etc/alertd/alert.conf | grep CPU alert BIGIP_SYSTEM_CHECK_E_CPU_TEMP_HIGH { lcdwarn description="CPU Temp too high." priority="3" alert BIGIP_SYSTEM_CHECK_E_AOM_CPU_TEMP_HIGH "Air Temperature near .*? Host.*? is too high .*?" { lcdwarn description="Air temperature near host CPU is too high" priority="3"
If you use ASM/AWAF module, you can monitor Total CPU Usage with ASM alerts :
