bytestore_chunkserver_tos_store_put_object_throughput	DanceDN	Metric deprecation	-	This change does not affect the normal operation of cloud product instances and your business. The related charts have disappeared from the monitoring dashboard, and the corresponding metrics cannot be specified during metric queries. If an exclamation mark (!) is added before an existing alert rule, it indicates that the alert rule contains a deprecated metric, and the alert will no longer be triggered. You need to remove the deprecated metric from the alert rule. If you do not remove or update the deprecated metric for an existing alert template, you cannot save the template. If you have configured this metric by using a custom dashboard created through the Grafana add-on, the related monitoring data will be unavailable. If you have configured this metric by using a custom observability dashboard, the related monitoring data will be unavailable.
