From 156b8f9c39a81cbbad7c32dbebdf321787611779 Mon Sep 17 00:00:00 2001 From: Romain Forlot Date: Wed, 22 Mar 2017 16:40:15 +0000 Subject: Send diag request only if not other one with some id running Fix: elapsed function return that do not compute elapsed_time at first time Fix: reworked should_send() to get it work with our scheduling workflow Reschedule trying to send request if recurring even it is in flight.
