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/K3667

You 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 :

    Hi Lidev ,

    Thanks for replying and Apology. I think my question is not clear.

    What we would like to know is about the CPU Utilizations and Memory Utilizations if more than 80%?

    Not on the environmental temperature heat value of the appliance.
