Hi. it's my first time using Dynatrace. I'm trying to create a new dashboard with AWS services as the source of the data. the first service I'm configuring is Lambda. based on requirements, I'm using a combination of built in metrics and "ext" metrics such as ext:cloud.aws.states.lambdaFunctionRunTimeByRegionLambdaFunctionArn. I'm trying to filter Lambda resources that start with a certain string. I'm able to filter it for built in metrics, but not for "ext" metrics. this is the same process as the SQL LIKE command, but I cannot figure out how to do it in Dynatrace. unfortunately, I cannot find any documentation for these "ext" metrics or the entity type custom_device_group. can anybody help me regarding this?
here is my wip command if it would be helpful. "lorem-ipsum" is just a placeholder.
ext:cloud.aws.states.lambdaFunctionRunTimeByRegionLambdaFunctionArn:filter(and(or(in("dt.entity.custom_device_group", entitySelector("type(custom_device_group),entityName.startsWith(lorem-ipsum)"))))):splitBy():percentile(95.0):sort(value(percentile(95.0),descending)):limit(20)
