Cannot convert Log attributes to Metric with Metric Aggregator

Hello.

I would like to use the Metric Aggregator to convert certain attributes (numbers) of Log data into metrics.
However, the attribute I want to convert to a metric does not appear in the “Select the attribute for your metric” field on the “Create a new aggregated metric” page.
How can I get it to appear?

thank you.

Hi @akito.iwamoto

Thanks for reaching out.

Great question, just for a little more context, can you confirm the business requirement for this.

Please see this is the doc: Introduction to creating metric data from non-metric data | New Relic Documentation as it will help you understand the process better.

Please do reach out should you have additional questions.

Looking forward to hearing from you!
