Board Management
Keepalive Tries
Range 0-3
Default 2
Description This is the number of consecutive keepalive failures that cause the
trigger of a recovery procedure. A keepalive failure is counted
when a keepalive timeout occurs and no response to the previous
keepalive enquiry has been received. A lower tries count allows a
more sensitive detection of failure, but with a higher chance of
false trigger in high load conditions. A value of 0 disables the
triggering of recovery procedures.
Failure Threshold Time
Range 1 to 1440
Default 15
Description This is the interval of time over which the a record of the number
of failures have been performed by the board management system.
This time is measured in minutes.
Failure Threshold Count
Range 1 to 10
Default 2
Description When a recovery procedure is triggered, board management
checks to see if the number of failures for the board over the last
Failure Threshold Time minutes has reached this number. If the
number of failures reaches this number, the board management
function deactivates the board without doing the recovery
procedure.
History Limit
Range 20
Default 20
Description This is the total number of events related to boards that the Board
Management Module stores. The number of events exceeding the
oldest record is removed to make room for the most recent event.
