DWQA QuestionsCategory: DatabaseHow to check the memory usage of dolphin DB node
trudy asked 4 weeks ago

I saw that in the user manual of dolphin DB database, the getclusterperf function can check the memory consumption of nodes, but I execute getclusterperf and the following error appears:

Only master or single mode supports function getClusterPerf

What’s the matter?

Getclusterperf can only be executed on the control node, so it can be executed by RPC remote call in the current node

rpc(getControllerAlias(),getClusterPerf)
