# Monitoring
|
|
|
|
|
|
|
|
|
|
By a stats endpoint, you are able to collect metrics for the plugin
|
|
|
|
|
within the interval. Note that only node level statistics collecting is
|
|
|
|
|
implemented for now. In other words, you only get the metrics for the
|
|
|
|
|
node you're accessing. Cluster level statistics have yet to be
|
|
|
|
|
implemented.
