How to Monitor for MetricDataQueries Validation Errors (Status Code: 400)

[wonderg]

Hello YACE community,

I've been encountering issues with metric collection, specifically due to ValidationError: The collection MetricDataQueries must not have a size greater than 500. These errors return a status code of 400 and are quite frequent in my logs. However, the metric yace_cloudwatch_request_errors remains at 0, even though my logs are full of these errors.

My objective is to monitor for these errors so I can set up alerts when they occur and take appropriate action. Is there any built-in YACE metric that can help identify such issues with MetricDataQueries size limitations or status code 400 errors? If not, could you suggest an alternative approach to detect and alert on these specific issues?

Any guidance on achieving robust monitoring and alerting around this would be highly appreciated.

Thanks in advance!
