Example 16 with CheckResult

use of zipkin2.CheckResult in project zipkin by openzipkin.

the class ElasticsearchStorage method ensureIndexTemplatesAndClusterReady.

/**
 * This allows the health check to display problems, such as access, installing the index
 * template. It also helps reduce traffic sent to nodes still initializing (when guarded on the
 * check result). Finally, this reads the cluster health of the index as it can go down after the
 * one-time initialization passes.
