Displaying active connections by client (cluster administrators only)
You can view the active connections by client to verify the node that a specific client is using and to view possible imbalances between client counts per node.
About this task
The count of active connections by client is useful in the following scenarios:
Finding a busy or overloaded node.
Determining why a particular client's access to a volume is slow.
You can view details about the node that the client is accessing and then compare it with the node on which the volume resides. If accessing the volume requires traversing the cluster network, clients might experience decreased performance because of the remote access to the volume on an oversubscribed remote node.
Verifying that all nodes are being used equally for data access.
Finding clients that have an unexpectedly high number of connections.
Verifying whether certain clients have connections to a node.
For more information about this command, see the man page.
