Librato Metrics

Hi, is anyone using librato service?
I'm using the GitHub - hubofthings/node-red-contrib-librato: A Node-RED node to send metrics to Librato. node.
The Metric is shown on librato, but it doesn't contain data.
Thanks!

I’d be wary about that node, it hasn’t been updated in 8 years.

That’s all I can offer since I’ve never heard about librato till now.
