Manage Peer Nodes
This topic contains information about peer nodes, including how to view and edit peer nodes, how to get a list of chaincodes installed on a peer, and how to find health information for a peer node.
View and Edit the Peer Node Configuration
A peer node’s configuration determines how the node performs and behaves on the network.
Only administrators can change a node’s configuration. If you've got user permissions, then you can view a node’s configuration settings. See Peer Node Attributes.
List Chaincodes Installed on a Peer Node
You can view a list of the chaincodes and their versions installed on a specific peer node in your network.
If you don’t see the chaincode or the chaincode version you were expecting, then you can install a chaincode or upgrade a chaincode to the peer node. You must be an administrator to install or upgrade a chaincode.
View Health Information for a Peer Node
You can check a peer node’s metrics to see how the node is performing on the blockchain network. This information helps you discover and diagnose performance problems.
The Health pane displays these performance
metrics: CPU utilization, memory utilization, user transactions endorsed, and user
transactions committed.
