Feature Overview
The Nodes page displays the status list for various roles in the cluster, which include FE, BE, BROKER.
For each role, the health status, process status, node IP and last restart time are displayed (which corresponds to the time of the last manual service restart operation on the Role Management page).
On the Nodes page, you can perform restart, and start operations on each node. The types of restart include immediate restart, graceful restart, and rolling restart. Batch execution for the same type of nodes is supported.
To ensure the high availability of each node, in addition to user's manual operations, each node runs a daemon process. If any node is detected to have an abnormal exit, the daemon process will immediately launch the corresponding node.
Note:
The restart operation generally takes 20-30 seconds. The page will automatically refresh to access the latest status during the execution.
Your operations on the Nodes page will be recorded on the Operation Logs page for any time reference.
