Cloud Database Redis
Updated at：2025-11-03
Cloud Database Redis monitors 12 object types: Redis - Community - Instance (RD_ST_INSTANCE), Redis - Community - Read Only Node (RD_ST_NODE_RO), Redis - Enterprise - Cluster (RD_CL_CLUSTER), Redis - Enterprise - Proxy (RD_CL_PROXY), Redis - Enterprise - Shard (RD_CL_SHARD), Redis Capacity CFS (Previously PegaDB) - Enterprise - Cluster (PG_CL_CLUSTER), Redis Capacity CFS (Previously PegaDB) - Enterprise - Proxy (PG_CL_PROXY), Redis Capacity CFS (Previously PegaDB) - Enterprise - Shard (PG_CL_SHARD), Memcache - Cluster (MC_CLUSTER), Memcache - Shard (MC_SHARD), Multi-site Group - Cluster (RD_CL_SYNC_FLOW_CLUSTER), and Multi-site Group - Shard (RD_CL_SYNC_FLOW_SHARD). The monitoring metrics for each type are listed as follows:
