icinga 一開始是 nagios 分支出來的一套同樣是監控系統
但比 nagios 整合了 ido2db (資料庫)、icinga-web (API) 在一起
web 介面除了有 classic UI (與 nagios 些微不同，且直覺) 之外，還有 icinga-web 介面 供 API 使用 (從資料庫撈)
操作跟 nagios 機乎差不多，那會用 icinga 基本上是因為有 RESTful API、Classic UI、及 可以期待 icinga 2版 ，也可詳看 Icinga vs. Nagios

# 安裝外掛，它還是用 nagios-plugins ，已到 2.0 版了
wget http://nagios-plugins.org/download/nagios-plugins-2.0.tar.gz tar zxvf nagios-plugins-2.0.tar.gz cd /root/nagios-plugins-2.0 ./configure --prefix=/usr/local/icinga --with-cgiurl=/icinga/cgi-bin --with-nagios-user=icinga --with-nagios-group=icinga --with-openssl --enable-perl-modules make make install
# 主設定檔
vi /usr/local/icinga/etc/icinga.cfg
# 註解參數，因為 log 顯示 config setting 'event_profiling_enabled' unknown ，我也不知道為什麼，就把它註解了 #event_profiling_enabled # or #sed -i 's/^event_profiling_enabled/#event_profiling_enabled/g' /usr/local/icinga//etc/icinga.cfg # 設定同時間可以處理的程序，預設為 0 ，即無限，但假如主機效能低的話，這個就不要太高，也有可能會有 session 問題 max_concurrent_checks=150 # or #sed -i 's/^max_concurrent_checks=.*/max_concurrent_checks=150/g' /usr/local/icinga/etc/icinga.cfg # 設定顯示時間格式，還是習慣看 2014-07-20 12:12:12 date_format=iso8601 # or #sed -i 's/^date_format=.*/date_format=iso8601/g' /usr/local/icinga/etc/icinga.cfg # 設定不要把 log 記錄到 /var/log/messages use_syslog=0 # or #sed -i 's/^use_syslog=.*/use_syslog=0/g' /usr/local/icinga/etc/icinga.cfg # 我把 flapping 關閉，因為打開會讓 check 出來時是無值的 enable_flap_detection=0
# 讓 classic UI 介面顯示全部列表，我不想一直下一頁下一頁
vi /usr/local/icinga/etc/cgi.cfg
result_limit=0 # or #sed -i 's/^result_limit=.*/result_limit=0/g' /usr/local/icinga/etc/cgi.cfg
# 設定支援 UTF8
# 這項其實是我原本有在 nagios 上設定，是為了讓 web UI可支援中文，在 icinga 我並沒有實際設定測試
# vi "/etc/httpd/conf.d/icinga.conf" <Directory "/usr/local/icinga/sbin"> # 加入 AddDefaultCharset UTF-8 # or #sed -i 35a'AddDefaultCharset UTF-8' "/etc/httpd/conf.d/icinga.conf" # vi /usr/local/icinga/etc/cgi.cfg escape_html_tags=0 # or #sed -i 's/^escape_html_tags=.*/escape_html_tags=0/g' /usr/local/icinga/etc/cgi.cfg
到這裡就
service httpd restart service icinga restart
並可瀏覽 Classic UI

# 補充，如何 upgrade icinga
在 make all 之後
make install install-base install-cgis install-html install-init install-commandmode install-idoutils # 資料庫，看原本版本號是多少，再一一匯入到最新的 mysql -u root -p icinga < icinga-core/module/idoutils/db/mysql/upgrade/mysql-upgrade-1.11.3.sql mysql -u root -p icinga < icinga-core/module/idoutils/db/mysql/upgrade/mysql-upgrade-1.11.6.sql mysql -u root -p icinga < icinga-core/module/idoutils/db/mysql/upgrade/mysql-upgrade-1.11.7.sql mysql -u root -p icinga < icinga-core/module/idoutils/db/mysql/upgrade/mysql-upgrade-1.12.0.sql mysql -u root -p icinga < icinga-core/module/idoutils/db/mysql/upgrade/mysql-upgrade-1.13.0.sql
