Graphite not writing info

Seems like the GraphiteWriter is not sending anything.

Did you make sure to enable Performance Data on your checks? This is done through the enable_perfdata option on the object level. It’s set to true by default, but maybe it’s changed in your setup. The setting may also be set in template.

Additionally, you could check if the solution from this thread works for you: Issue: GraphiteWriter not writing Performance Data to Carbon-Cache
