This is a fairly new Graphite installation on CentOS 6.5. It's receiving metrics via AMQP (RabbitMQ) from Sensu.
As a proof-of-concept, I have a load-average monitor reporting data to sensu/graphite every 60 seconds. I can see the data arriving in Graphite's listener log.
If I select some data for graphing, I can only see data if my period is within "the past 30 minutes." (Then it's only visible if I set the line mode to "connected line" because the points disappear.)
If I set the period to "View past 31 minutes" all of the data disappears from the graph.
I've tried playing with the storage-schemas.conf but haven't made any appreciable change in this behavior.
If I go over 30 minutes, is the data somehow being thrown away, filtered out? What would I check?
This is storage-schemas.conf:
[load_averages] pattern = \.load_avg\. retentions = 10s:14d,1m:90d
