    1-Minute Granularity Will Be Disused

      CM will discontinue the 1-minute granularity alarm policy for TencentDB for Redis and QCE/REDIS namespace, which will have the following impacts:
      You can't receive the alarm notification of TencentDB for Redis Memory Edition (1-minute granularity).
      Data can't be displayed on the dashboard of TencentDB for Redis Memory Edition (1-minute granularity).
      You can't pull the monitoring data of TencentDB for Redis Memory Edition (1-minute granularity).
      Migration Schemes
      Alarm policy: You need to migrate the alarm policy of the existing TencentDB for Redis instances with 1-minute monitoring granularity to those with 5-second monitoring granularity. Click to view the mappings of metrics.
      Dashboard: You need to migrate the dashboard of the existing TencentDB for Redis instances with 1-minute monitoring granularity to 5-second monitoring granularity. Click to view the mappings of metrics.
      Pulling monitoring metric data through APIs: You need to switch QCE/REDIS to QCE/REDIS_MEM, and modify the names of pulled metrics simultaneously.
      Because 1-minute monitoring granularity of TencentDB for Redis is not completely the same as the metric names in Mappings of Metrics. This document describes the mappings of monitoring metrics of TencentDB for Redis 1-minute monitoring granularity and 5-second monitoring granularity for you to compare and migrate.
