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 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 (推荐自定义一个host模版)
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
下面开始演示添加主机:添加前:
引用代码:
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 centreondatabase ### ==================================================== use strict; use warnings; use DBI; use DBD::MySQL; # ---------------------------------------------------- my $DB_HOST = "10.199.95.165"; my $DB_USER = "centreon"; my $DB_PASSWD = "centreon"; my $DB_NAME = "centreon"; my $dbh= DBI->connect("DBI:mysql:database=$DB_NAME;host=$DB_HOST","$DB_USER", "$DB_PASSWD", { RaiseError=> 1 }); # ---------------------------------------------------- my $file_path = "hosts"; my $tpl_name= "generic-host"; my $nagios_name= "Central"; while (defined(my $arg= shift)) { if ($arg eq '-f') { $file_path= shift; } # == name of template == elsif($arg eq '-t') { $tpl_name= shift; } # == name of nagiosname == elsif($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($line =)) { # == skip blank lines ================= next if ($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',host_obsess_over_host='2',host_check_freshness='2'"; $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_idis $host_id\n"; } next if ($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 "nagiosid 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); $dbh->disconnect(); exit 0; #-------------------------------------------------------------------------------- sub print_help{ print "Usage ./insert_host.pl [-f path of host file][-n nagiosname] [-t template name]\n"; print "\n"; }
添加后:刷新WEB页面:多了三台;
批量生成和主机相关联的服务
上面的脚本能够批量添加主机,但是不能自动生成和主机相关联的服务
使用 CentreonCLAPI 可以解决这个问题,CentreonCLAPI 是centreon 命令行接口,可以替代在网页上的许多工作,这里我们只介绍下怎么解决我们的问题。了解更多请看网址:
http://forge.centreon.com/projects/centreon-clapi/wiki
进行安装
http://download.centreon.com/Modules/CLAPI/centreon-clapi-1.1.tar.gz
tar zxvfcentreon-clapi-1.1.tar.gz
cd centreon-clapi-1.1
提示输入instCentWeb.conf配置文件的路径:/usr/local/centreon/etc/
安装完成后:
cd /usr/local/centreon/www/modules/centreon-clapi/core/
vimcentreon +64
require_once "$centreon_etc/centreon.conf.php";
改为:
require_once "/usr/local/centreon/etc/centreon.conf.php";
cd /usr/local/centreon/www/modules/centreon-clapi/core/
vim centreon +64
require_once"$centreon_etc/centreon.conf.php";
改为:
require_once"/usr/local/centreon/etc/centreon.conf.php";
对client主机应用所关联的模板服务:
关联前:
进行关联:
[root@mastercore]# ./centreon -uadmin-padmin123 -o HOST -a applytpl -v"cc.cc.cc.cc"
查看页面:
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:
刷新页面查看:
批量添加完主机和服务要需要重新生成nagios配置后生效。
