I want to configure Alert only for Out of Memory Error & CPU usage reach threshold here what I did

Out of Memory Error:
Settings -> Alerting -> Problem alerting profiles -> Add alerting profile & provided below details
Name: OOME
Selected zone under Management Zone
Severity filter kept as it is
Under Add event filter -> Title contains java.lang.OutOfMemoryError for Custom

CPU usage:
Anomaly detection -> Metric events -> under Add metric event, in Metric key selected CPU usage%

I’ve configured Alerts as above. Is it correct way?

I’m able to integrate Out of Memory Error Alert but unable integrate CPU usage
Can someone help me?
