Can I send strings to New Relic?

Question

I want to send metrics to New Relic with string as the value, but I can't find any docs on how to do that. Are metrics limited to numerical values by New Relic?

Answer 1

All reported metrics are required to be numerical. In some places the metric name will be exposed but it will always be tied to a numerical value.
