Description:
6
+
The maximum number of times the balloon driver will
7
+
attempt to increase the balloon before giving up. See
8
+
also 'retry_count' below.
9
+
A value of zero means retry forever and is the default one.

Description:
16

The limit that 'schedule_delay' (see below) will be

Description:
24
+
The current number of times that the balloon driver
25
+
has attempted to increase the size of the balloon.
26
+
The default value is one. With max_retry_count being
27
+
zero (unlimited), this means that the driver will attempt
28
+
to retry with a 'schedule_delay' delay.

34

Description:
35
+
The time (in seconds) to wait between attempts to
36
+
increase the balloon. Each time the balloon cannot be
37
+
increased, 'schedule_delay' is increased (until
38
+
'max_schedule_delay' is reached at which point it
39
+
will use the max value).
