Module: nagiosplug Branch: master Commit: e11b67f6200b994c6d8118948a36eb0ed43bec5a Author: Holger Weiss <[email protected]> Date: Thu Mar 18 00:34:14 2010 +0100 URL: http://nagiosplug.git.sf.net/git/gitweb.cgi?p=nagiosplug/nagiosplug;a=commit;h=e11b67f Let check_ntp_peer check the number of truechimers Add support for checking the number of usable time sources (i.e., the number of peers which are classified as so-called "truechimers" by NTP's intersection algorithm). The new "-m" and "-n" options allow for specifying the according WARNING and CRITICAL thresholds (and thereby activating the truechimers check), respectively. --- NEWS | 1 + plugins/check_ntp_peer.c | 72 ++++++++++++++++++++++++++++++++++++--------- plugins/t/check_ntp.t | 24 +++++++------- 3 files changed, 70 insertions(+), 27 deletions(-) diff --git a/NEWS b/NEWS index 4a55502..c555dda 100644 --- a/NEWS +++ b/NEWS @@ -2,6 +2,7 @@ This file documents the major additions and syntax changes between releases. 1.4.15 ...
