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.
