一、centreon批量添加主机
本部分参考了同事的文档和链接:
centreon的模板功能是做的非常强大的,而且优化过的nagios配置十分简单,加host的时候只需要输入了hostname,alias和ip 地址就可以加一台host上去,service配在hostgroup上,这样只要把host添加到hostgroup上就可以了。 如果你要加一两台机器,那是很方便的,但是如果上百台呢,上千台呢?那手岂不是要点的抽筋了? 这点来看,还是用脚本批量添加来的方便,呵呵,共享一个自己写的批量添加host的脚本,只添加host,service和hostgroup自己配。 运行脚本之前,要先准备好几件事情: 1、要有一个host的模板,将所有的属性基本上定义完整,使用脚本添加的host会和模板一模一样,只有ip地址和hostname有差别 2、要确认了host要添加到哪台nagios上,在centreon里叫poller 3、要有一个hosts文件,里面内容为要批量添加的hostname和ip地址,类似/etc/hosts的格式,第一栏ip,第二栏hostname 脚本用perl写的,最前面db的部分需要修改,代码如下: #!/usr/bin/perl ## ==================================================== # # File name: insert_host.pl # Use: insert host into centreon database # Creater: lianming # Date: 2009-04-24 # Last_change: 2009-04-24 # ## ==================================================== use strict; use warnings; use DBI; use DBD::mysql; # ---------------------------------------------------- my $DB_HOST = "db_ipaddress"; #修改为127.0.0.1my $DB_USER = "db_user"; # 安装时设置的数据库访问用户,修改为centreonmy $DB_PASSWD = "db_password"; # web安装时设置的数据库密码,修改为centreonmy $DB_NAME = "centreon"; # web安装时设置的数据库名,默认也是centreon my $dbh = DBI->connect("DBI:mysql:database=$DB_NAME;host=$DB_HOST", "$DB_USER", "$DB_PASSWD", { RaiseError => 1 }); # ---------------------------------------------------- my $file_path = "./hosts"; #hosts文件,自己创建my $tpl_name = "generic-host"; #主机模板,填写你需要继承的模板;my $nagios_name = "nagios_name"; #poller,修改为Central foreach my $arg (@ARGV) { # == file of hostname and ipaddress == if ($arg eq '-f') { $file_path = shift; } # == name of template == elsif ($arg eq '-t') { $tpl_name = shift; } # == name of nagios name == elsif ($arg eq '-n') { $nagios_name = shift; } else { &print_help(); exit 1; } } # ----------------------------------------------------- open (HOST, "$file_path") || die "Cannot open $file_path for read"; my $sql; my $sth; my $line; my ($host, $ipaddr); my ($host_id, $tpl_id, $nagios_id) = (0, 0, 0); while (defined($line = <HOST>)) { # == skip blank lines ================= next if ($line =~ /^\s*$/);
# == skip if # ======================== next if ($line =~ /^\s*#/); # == get host and ipaddress =========== ($ipaddr, $host) = split(/\s+/, $line); next if ($ipaddr eq '' || $host eq ''); # == insert the host to table host ==== $sql = "insert host set host_template_model_htm_id='2',host_name='$host',host_alias='$host',host_address='$ipaddr',host_active_checks_enabled='2',host_passive_checks_enabled= '2',host_checks_enabled='2',host_event_handler_enabled='2',host_flap_detection_enabled='2',host_process_perf_data='2',host_retain_status_information= '2',host_retain_nonstatus_information='2',host_notifications_enabled='2',host_register='1',host_activate='1'";
$sth = $dbh->do($sql); sleep(1); # == get host_id ====================== $sql = "select host_id from host where host_name='$host'"; $sth = $dbh->prepare($sql); $sth->execute(); while (my $ref = $sth->fetchrow_hashref()) { $host_id = $ref->{'host_id'}; print "host_id is $host_id\n"; } next if ($host_id == 0); # == insert extended_host_information == $sql = "insert extended_host_information set host_host_id='$host_id'"; $sth = $dbh->do($sql); # == insert host_template_relation ===== $sql = "select host_id from host where host_name='$tpl_name'"; $sth = $dbh->prepare($sql); $sth->execute(); while (my $ref = $sth->fetchrow_hashref()) { $tpl_id = $ref->{'host_id'}; print "template id is $tpl_id\n"; } next if ($tpl_id == 0); $sql = "insert host_template_relation set host_host_id='$host_id',host_tpl_id='$tpl_id',`order`='1'"; $sth = $dbh->prepare($sql); $sth->execute(); # == insert ns_host_relation =========== $sql = "select id from nagios_server where name='$nagios_name'"; $sth = $dbh->prepare($sql); $sth->execute(); while (my $ref = $sth->fetchrow_hashref()) { $nagios_id = $ref->{'id'}; print "nagios id is $nagios_id\n"; } next if ($nagios_id == 0); $sql = "insert ns_host_relation set host_host_id='$host_id',nagios_server_id='$nagios_id'"; $sth = $dbh->prepare($sql); $sth->execute(); # == insert complete == print "insert $host to centreon complete\n"; } close(HOST); $dbh->disconnect(); exit 0; # -------------------------------------------------------------------------------- sub print_help { print "Usage ./insert_host.pl [-f path of host file] [-n nagios name] [-t template name]\n"; print "\n"; }

上面的脚本名我换成了add_host.pl,并创建hosts文件:

二、批量生成和主机相关联的服务
注:此部分引用了同事的文档和脚本~
上面的脚本能够批量添加主机,但是不能自动生成和主机相关联的服务,如果对每一台主机增加一个服务,要一个一个在页面点击,非常麻烦。
使用 Centreon CLAPI 可以解决这个问题,Centreon CLAPI 是centreon 命令行接口,可以替代在网页上的许多工作,这里我们只介绍下怎么解决我们的问题。了解更多请看网址:
安装clapi:
[root@centreon ~]# cd /usr/local/src/
[root@centreon src]# tar zxf centreon-clapi-1.1.tar.gz
[root@centreon src]# cd centreon-clapi-1.1
[root@centreon centreon-clapi-1.1]# ./install.sh -i
提示输入instCentWeb.conf配置文件的路径:/usr/local/centreon/etc/
[root@centreon centreon-clapi-1.1]# cd /usr/local/centreon/www/modules/centreon-clapi/core/
[root@centreon core]# vi +64 centreon
require_once "$centreon_etc/centreon.conf.php";
改为:
require_once "/usr/local/centreon/etc/centreon.conf.php";
查看所有主机:
[root@centreon core]# ./centreon -uadmin -p111111 -o HOST -a show
查看主机名包含client-1的主机,如果是输入client,则会显示client,client-1,client-2
[root@centreon core]# ./centreon -uadmin -p111111 -o HOST -a show -v "client-1"
对client主机应用所关联的模板服务:
[root@centreon core]# ./centreon -uadmin -p111111 -o HOST -a applytpl -v "client-1"
执行命令前的服务:
执行后client-1服务都已添加:
通过以上命令可以关联模板的服务,如果需要批量添加,只需写个简单的脚本就能实现,见下图,执行前可删除刚才手动执行的命令添加的client服务:
WEB刷新服务:
批量添加完主机和服务要需要重新生成nagios配置后生效。
