Hi Team, Is it possible to create CloudWatch alerts based on the error code from Oracle DB logs. Like trigger alert for ORA-XXX error from logs?

If the logs are in CloudWatch logs, then you can create a metric from the log stream and alert on that

Yes the are in CloudWatch logs. I have created some alerts based on existing cloudwatch matrics. Can you please point me how can I create matric from log stream? Thanks

Use a filter to match the specific pattern in your log https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/MonitoringLogData.html and write this out to a CloudWatch metric. Then setup an alarm on the metric as you have done already.

I have a quick question regarding patterns, I have few error code which I want them to check all in logs and alert.
