CirrusHi F5 community,
Can F5 system capable to send email notifications alert if CPU and Memory is more than 80%?
We tried to check in user_alert.conf and alert.conf we don't see any description.
May we know what did you do on your side to provide this requirement? Thanks in advance.
MVPHi 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 :
