perago.restart_backoff_seconds

perago.restart_backoff_seconds(restart_count)

Return the supervisor restart delay for a child process.

The sequence is intentionally short and bounded so a crashing child backs off without permanently stopping the supervisor. Counts beyond the explicit sequence use the maximum delay.

Parameters:

restart_countint

Zero-based number of previous restarts for the child slot.

Returns:

int

Delay in seconds before the supervisor starts the replacement process.

Raises:

ValueError

If restart_count is negative.

参数:

restart_count (int)

返回类型:

int
