From 4621427ba8cbfab4815e65d35a728ad51ad8c391 Mon Sep 17 00:00:00 2001 From: rincewind Date: Sat, 25 Sep 2021 23:24:45 +0200 Subject: check_swap: Fix perfdata und thresholds for big values and simplify code The original problem was https://github.com/monitoring-plugins/monitoring-plugins/pull/1705 where the performance data output of check_swap did not conform to the parser logic of a monitoring system (which decided to go for "correct" SI or IEC units. The PR was accompanied by a change to byte values in the performance data which broke the _perfdata_ helper function which could not handle values of this size. The fix for this, was to use _fperfdata_ which could, but would use float values. I didn't like that (since all values here are discreet) and this is my proposal for a fix for the problem. It introduces some helper functions which do now explicitely work with (u)int64_t, including a special version of the _perfdata_ helper. In the process of introducing this to check_swap, I stumbled over several sections of the check_swap code which I found problematic. Therefore I tried to simplify the code and make it more readable and less redundant. I am kinda sorry about this, but sincerely hope my changes can be helpful. --- plugins/check_swap.c | 239 +++++++++++++++++++++++++++++---------------------- 1 file changed, 137 insertions(+), 102 deletions(-) (limited to 'plugins/check_swap.c') diff --git a/plugins/check_swap.c b/plugins/check_swap.c index 0ff0c770..25bcb3d5 100644 --- a/plugins/check_swap.c +++ b/plugins/check_swap.c @@ -34,6 +34,10 @@ const char *email = "devel@monitoring-plugins.org";
