Node Score
What is a "NodeScore"?
What is a Connection Broker?
The CentraStage agent will poll the CentraStage platform every 90 seconds with keep alive messages. If there is more than one CentraStage agent on a LAN, one of those agents will be automatically designated as a Connection Broker (CB) which will deal with all the pings and keep-alives from the other devices on the LAN. This keeps the outbound/public traffic to a minimum.
What is a “Node Score”?
Agents on each device added to the CSM will obtain a ranking to determine whether it is to be established as a Connection Broker (CB) and Device Discovery/SNMP polling node. The Node Score is calculated when a device runs an audit. An agent will only respond to a Connection Broker request if it's NodeScore is equal to or greater than the NodeScore of the requesting agent, this ensures the most robust device on the network will become the Connection Broker for the subnet. If 2 or more devices gain the same ranking score, a most suitable/stable determination is made as to which device should be chosen.
Agents are graded on a score of between 0 and 19, 0 being the least suitable and 19 the most suitable to be used as a Connection Broker. The Node score is calculated from the following areas:
•
Network Connection Type
•
Operating System Type
•
Days since last System boot
The score will be generated through the following score process:
What is a "NodeScore"? Rank = 0
Connected via Ethernet or Wi-Fi?
Ethernet + 5
Wi-Fi + 0
Operating system?
Client + 0
Server + 5
Days since reboot?
