Viewing information about DataMiner nodes

To get information on the individual DataMiner nodes (also known as DataMiner Agents) in a cluster, in DataMiner Cube, go to Apps > System Center > Agents.

This page contains several tabs with information and settings:

• To see the total number of nodes in the cluster, check the top of the Agents column in the manage tab.

• To see the state of a specific node in the cluster, look for the node in the Agents column in the manage tab. The state of the node is displayed in parentheses next to its name. Select a node to view detailed information on alarms for this node in the pane on the right.

  A node can have the following states:

  State	Description
  Not running	The node is currently not running.
  Running	The node is running.
  Starting	The node is starting up.
  Switching	The node is part of a Failover pair and a Failover switch is currently happening. See Failover.
  Leaving Cluster	The node is currently leaving the cluster.
  Joining Cluster	The node is currently joining the cluster.
  Unknown	The node state and connection state are currently not known.

  If the state of the node is unknown, but the connection state is known, the connection state is shown instead. A node can have the following connection states:

  Connection state	Description
  Normal	The connection is OK.
  Other cluster	The node is not part of the current cluster. This can mean that it is part of another cluster, or that it is not part of a cluster at all.
  Version conflict	There is a version conflict between the node and the node you are connected to.
  Refused	The connection with the node has been temporarily refused.
  Invalid	Invalid configuration makes it impossible to communicate with the node.
  Disconnected	The node cannot be reached.

  Note

  For more information on how to check the exact cause for a refused connection, see Checking or modifying the settings related to a Refused DMA state. However, note that this involves advanced settings that should only be modified by administrators, as changing these can have far-reaching consequences on the functionality of your DataMiner System.

• To view key parameters of all the nodes in the system, such as the processor load, the server uptime, and the total number of elements per node, go to the status tab.

• To view contacts responsible for the system, for instance in case you encounter an issue and want to contact an administrator, go to the system tab.

• The bpa tab is used to run BPA tests. See Running BPA tests
