Feeding Metrics to Moira¶
Moira needs to keep its own local copy of your metric data to improve performance and reduce load on your existing graphite cluster. This means data needs to be duplicated from your existing stream and sent to your existing cluster and to your Moira installation.
Unfortunatly, the Carbon-Relay with Graphite does not support duplication of data to multiple backends, and so you need to use a more feature rich carbon relay such as carbon-c-relay.
The following is a basic example configuration which defines two clusters and sends all metrics to both at once. One cluster is Moira installation, and the other uses consistent hashing across a three node cluster of Carbon servers.
cluster moira forward moira-host:2003 ; cluster graphite carbon_ch 127.0.0.1:2006=a 127.0.0.1:2007=b 127.0.0.1:2008=c ; match * send to moira graphite ;
