From 56ad762bd3bd59e5dac1ecb0e87c0b69f4ebaffc Mon Sep 17 00:00:00 2001 From: Lorenz Kästle <12514511+RincewindsHat@users.noreply.github.com> Date: Wed, 12 Mar 2025 11:16:04 +0100 Subject: Remove check_overcr This commit removes the plugin check_overcr and all related files and parts of files. OverCR seems to be dead and I have never seen a mention of an active usage anywhere. The website still does exist, but the activity seems to be limited. Carrying check_overcr forward seems to be a burden without a purpose and more of an opportunity to remove some code. --- plugins/Makefile.am | 3 +- plugins/check_overcr.c | 417 ------------------------------------------------- 2 files changed, 1 insertion(+), 419 deletions(-) delete mode 100644 plugins/check_overcr.c (limited to 'plugins') diff --git a/plugins/Makefile.am b/plugins/Makefile.am index 9ea6e85e..6c582a15 100644 --- a/plugins/Makefile.am +++ b/plugins/Makefile.am @@ -27,7 +27,7 @@ MATHLIBS = @MATHLIBS@ #AM_CFLAGS = -Wall libexec_PROGRAMS = check_apt check_cluster check_disk check_dummy check_http check_load \ - check_mrtg check_mrtgtraf check_ntp check_ntp_peer check_nwstat check_overcr check_ping \ + check_mrtg check_mrtgtraf check_ntp check_ntp_peer check_nwstat check_ping \ check_real check_smtp check_ssh check_tcp check_time check_ntp_time \ check_ups check_users negate \ urlize @EXTRAS@ @@ -132,7 +132,6 @@ check_nt_LDADD = $(NETLIBS) check_ntp_LDADD = $(NETLIBS) $(MATHLIBS) check_ntp_peer_LDADD = $(NETLIBS) $(MATHLIBS) check_nwstat_LDADD = $(NETLIBS) -check_overcr_LDADD = $(NETLIBS) check_pgsql_LDADD = $(NETLIBS) $(PGLIBS) check_ping_LDADD = $(NETLIBS) check_procs_LDADD = $(BASEOBJS) diff --git a/plugins/check_overcr.c b/plugins/check_overcr.c deleted file mode 100644 index 599540b7..00000000 --- a/plugins/check_overcr.c +++ /dev/null @@ -1,417 +0,0 @@ -/***************************************************************************** - * - * Monitoring check_overcr plugin - * - * License: GPL - * Copyright (c) 2000-2024 Monitoring Plugins Development Team - * - * Description: - * - * This file contains the check_overcr plugin - * - * This plugin attempts to contact the Over-CR collector daemon running on the - * remote UNIX server in order to gather the requested system information. - * - * - * This program is free software: you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
