批量添加主機和服務
centreon的模板功能是做的非常強大的,而且優化過的nagios配置十分簡單,加host的時候只需要輸入了hostname,alias和ip 地址就可以加一臺host上去,service配在hostgroup上,這樣只要把host添加到hostgroup上就可以了 只添加host,service和hostgroup自己配。運行腳本之前,要先準備好幾件事情:
1、要有一個host的模板,將所有的屬性基本上定義完整,使用腳本添加的host會和模板一模一樣,只有ip地址和hostname有差別 (推薦自定義一個host模版)
2、要確認了host要添加到哪臺nagios上,在centreon里叫poller
3、要有一個hosts文件,里面內容為要批量添加的hostname和ip地址,類似/etc/hosts的格式,第一欄ip,第二欄hostname
下面開始演示添加主機:添加前:
引用代碼:
腳本用perl寫的,最前面db的部分需要修改,代碼如下: #!/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($line = <HOST>)) { # == skip blank lines ================= next if ($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',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); $dbh->disconnect(); exit 0; #-------------------------------------------------------------------------------- sub print_help{ print "Usage ./insert_host.pl [-f path of host file][-n nagiosname] [-t template name]\n"; print "\n"; }
添加后:刷新WEB頁面:多了三臺;
批量生成和主機相關聯的服務
上面的腳本能夠批量添加主機,但是不能自動生成和主機相關聯的服務
使用 CentreonCLAPI 可以解決這個問題,CentreonCLAPI 是centreon 命令行接口,可以替代在網頁上的許多工作,這里我們只介紹下怎么解決我們的問題。了解更多請看網址:
http://forge.centreon.com/projects/centreon-clapi/wiki
進行安裝
http://download.centreon.com/Modules/CLAPI/centreon-clapi-1.1.tar.gz
tar zxvfcentreon-clapi-1.1.tar.gz
cd centreon-clapi-1.1
提示輸入instCentWeb.conf配置文件的路徑:/usr/local/centreon/etc/
安裝完成后:
cd /usr/local/centreon/www/modules/centreon-clapi/core/
vimcentreon +64
require_once "$centreon_etc/centreon.conf.php";
改為:
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";
改為:
require_once"/usr/local/centreon/etc/centreon.conf.php";
對client主機應用所關聯的模板服務:
關聯前:
進行關聯:
[root@mastercore]# ./centreon -uadmin-padmin123 -o HOST -a applytpl -v"cc.cc.cc.cc"
查看頁面:
通過以上命令可以關聯模板的服務,如果需要批量添加,只需寫個簡單的腳本就能實現,見下圖,執行前可刪除剛才手動執行的命令添加的client服務:
刷新頁面查看:
批量添加完主機和服務要需要重新生成nagios配置后生效。
