From ef999f8f451043bfa0ae281149592ab190839fd9 Mon Sep 17 00:00:00 2001 From: Thomas Guyot-Sionnest Date: Fri, 23 Nov 2007 04:21:09 +0000 Subject: - Use max_state_alt in check_ntp to fix some issues with the latest commits. - Roll back the stratum check as there were issues with it and a better one is already implemented in check_ntp_peer (about to be included) git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1830 f882894a-f735-0410-b71e-b25c423dba1c --- plugins/check_ntp.c | 63 +++++++++-------------------------------------------- 1 file changed, 10 insertions(+), 53 deletions(-) (limited to 'plugins') diff --git a/plugins/check_ntp.c b/plugins/check_ntp.c index 28541616..38562ac9 100644 --- a/plugins/check_ntp.c +++ b/plugins/check_ntp.c @@ -50,9 +50,6 @@ static int verbose=0;
