    Get Responses Get-Response PDUs sent.
    Traps Trap PDUs sent.
    Drops
    Silent Drops PDUs delivered but silently dropped because the size of a reply containing an alternate response PDU with an empty variable-bindings field was greater than either a local constraint or the maximum message size associated with the originator of the requests.
    Proxy Drops PDUs delivered but silently dropped because the transmission of the message to a proxy target failed in such a way (other than a timeout) that no response PDU could be returned.
  2. When the server is part of a cluster, the Cluster Node field identifies the node, and the change button allows you to change nodes, and display statistics for that node.
