０．改訂履歴

2005.08.29　新規作成
2005.09.13　webインタフェイス部分の設定追加．
2007.10.11　Pluginについて追記．

１．はじめに

　　このドキュメントではサーバシステム監視ツールでnagiosのインストールある手順を説明する．

　nagiosとは，オープンソースのホスト，サービス，ネットワークのモニタリングツールで，商用製品ではhpのOpenView，IBMのTivoli，日立のJP1/cm2等が同様のカテゴリになる．同じオープンソースではOpenNMSというJavaベースのものがある．　Nagiosは昔，NetSaintという名称で配布されていたようですが，名前が変更になっているようである．　　今回インストールに際してNet::SNMPとそれに伴うDigest::Base,Crypt::DES,Digest::HMAC.Digest::SHA1等のPerl用モジュールの追加と，fpingの導入も行っている．

２．nagiosモジュールを入手してインストールする

[root@jupiter shinnai]#

そのファイル以外に，専用のアカウント＆グループが作成された事を確認する．

[root@jupiter nagios]# cat /etc/passwd|grep nagios
nagios:x:100:101:nagios:/var/log/nagios:/bin/sh
[root@jupiter nagios]# cat /etc/group|grep nagios
nagios:x:101:apache
[root@jupiter nagios]#

分かりやすい名前で？作られているようである．

３．メインファイルの設定する

メイン設定ファイルを探す．

[root@jupiter nagios]# rpm -ql nagios-1.2-2.1.el3.rf.i386|grep nagios.cfg
/etc/nagios/nagios.cfg
[root@jupiter nagios]

このファイル内で設定する代表的な項目は，次の通り．

設定項目	説明
`log_file`	nagiosのイベントを記録していくファイルを指定する．
`cfg_file`	監視対象の情報を保管するファイルを指定する．
`resource_file`	プラグインをインストールしているディレクトリを指定する．
`status_file`	すべての監視対象のステータスを記録するファイルを指定．　nagiosを起動する都度，このファイルは古いものが消えるて新しいファイルが作成される．
`nagios_user`	nagiosを実行する際のUNIX上のユーザアカウントを指定する．
`nagios_group`	nagiosユーザが所属するUNIX上のグループを指定する．
`log_rotation`	ログのローテーションを指定する．毎時間，毎日，毎週，毎月，なしを設定する事ができる．
`log_archive_path`	ログローテーションしたファイルの保存先を指定する．
`service_check_timeouthost_check_timeout`	nagiosが実行したコマンドのタイムアウト時間を秒単位で指定する．
`interval_length`	監視間隔を秒単位で指定する．
`downtime_file`	監視対象の停止時間を記録するファイル．
`date_format`	日付フォーマット．　iso8601形式にするとYYYY-MM-DD HH:MM:SSとなる．
`admin_email`	nagiosが稼働するサーバの管理者用メールアドレス．

主にファイルの保存先等に関する情報なので，特別に必要がなければ設定するところは無い．
日付と管理者用メアドを設定．

４．監視の設定を行う

ここから，実際の監視の設定を行っていく．
まずは，監視設定ファイルがどこにあるか確認する．

[root@jupiter nagios]# pwd
/etc/nagios
[root@jupiter nagios]# ls -la

[root@jupiter nagios]#

nagiosが障害を検知した時に通知を行う先を設定する．
下記では，自分のPC用のメールアドレスの通知先(shinnai)と，携帯電話のメールアドレスの通知先(shinnai-mobile)の２つを定義した．

contacts.cfg

# shinnai contact definition
define contact{
        contact_name                    ujp_pc
        alias                           PC mail
        service_notification_period     workhours
        host_notification_period        workhours
        service_notification_options    c,r
        host_notification_options       d,r
        service_notification_commands   notify-by-email
        host_notification_commands      host-notify-by-email
        email                           webadmin@whitehouse.com
        }
# shinnai mobile contact definition
define contact{
        contact_name                    ujp_mobile
        alias                           Nobuaki Shinnai mobile
        service_notification_period     workhours
        host_notification_period        workhours
        service_notification_options    c,r
        host_notification_options       d,r
        service_notification_commands   notify-by-email
        host_notification_commands      host-notify-by-email
        email                           mobilemailaddress@ezweb.ne.jp
        }

次に，通知先のグルーピングを行う．

contactgroups.cfg
define contactgroup{ contactgroup_name office-admins alias Tokyo office-admin members ujp_pc,ujp_mobile }

office-adminsという通知先グループを作成し，そのメンバーにcontacts.cfgで定義したPC用と携帯電話用の定義名を設定した．
次に，host.cfgファイルにて監視対象となる機器（コンピュータ等）の情報を指定する．
次のように定義してある

host.cfgのサンプル

define host{
        use                     generic-host    ; Name of host template to use

        host_name               novell1
        alias                   Novell Server #1
        address                 192.168.1.2
        check_command           check-host-alive
        max_check_attempts      10
        notification_interval   120
        notification_period     24x7
        notification_options    d,u,r
        }

これをもとに設定する．

hosts.cfg

# 'novell1' host definition
define host{
        use                     generic-host
        host_name               mars
        alias                   testsesrver
        address                 210.123.123.128
        check_command           check-host-alive
        max_check_attempts      10
        notification_interval   120
        notification_period     24x7
        notification_options    d,u,r
        }

define host{
        use                     generic-host
        host_name               jupiter
        alias                   nagios server
        address                 210.123.123.127
        check_command           check-host-alive
        max_check_attempts      10
        notification_interval   120
        notification_period     24x7
        notification_options    d,u,r
        }

ここでは，ホストの死活監視(check-host-alive)を週７日24時間(24x7)
notificatin_interval=120なので，120分経過したら再通知．
max_check_attemptsが10なので，10回リトライ．

marsとjupiterというコンピュータを登録した．

notification_optionsの設定項目
フラグ	意味
w	warning
u	unreachable
c	critical
r	recovery

次に，機器のグルーピングを行う為に，hostgroups.cfgを設定する．

hostgroups.cfg
define hostgroup{ hostgroup_name office-servers alias Tokyo Office Server contact_groups office-admins members mars,jupiter }

先ほど定義したコンピュータmarsとjupiterを，office-serversというグループとした．
このサーバグループに障害が発生した場合には，contactgroups.cfgに定義したoffice-adminsグループ，つまり，contacts.cfgに定義したshinnai,shinnai-mobile宛に通知が行く事となる．

escalations.cfg

define serviceescalation{
        host_name                       mars   
        service_description             PING
        first_notification              2
        last_notification               6
        contact_groups                  office-admins
        notification_interval           0
        }

define serviceescalation{
        host_name                       jupiter
        service_description             PING
        first_notification              2
        last_notification               6
        contact_groups                  office-admins
        notification_interval           0
        }

３回失敗したら４回目で障害通知．
notification_intervalは５秒間隔で再チェック．これを０に設定すると，一度通知した障害は再送信しない．
次に，監視するサービスの設定を行う．
ここでは，一番簡単なサーバの死活監視をPINGで行う設定とする．

services.cfg

define service{
        use                     generic-service
        host_name               mars
        service_description     PING    
        is_volatile             0       
        check_period            24x7    
        max_check_attempts      3       
        normal_check_interval   5       
        retry_check_interval    1       
        contact_groups          office-admins
        notification_interval   120     
        notification_period     24x7    
        notification_options    c,r     
        check_command           check_ping!100.0,20%!500.0,60%
        }

define service{
        use                     generic-service 
        host_name               jupiter
        service_description     PING
        is_volatile             0
        check_period            24x7
        max_check_attempts      3
        normal_check_interval   5
        retry_check_interval    1
        contact_groups          office-admins
        notification_interval   120
        notification_period     24x7
        notification_options    c,r
        check_command           check_ping!100.0,20%!500.0,60%
        }

このように２つのサーバを監視対象とし，pingにて監視を行う．
ここまで設定できたら，nagiosの設定ファイルを確認してみる．

Things look okay - No serious problems were detected during the pre-
flight check

[root@jupiter nagios]#

今回はエラーが発生しなかった模様．

５．nagiosを起動・停止・リロードする

設定が完了したら，nagiosを起動してみる．

[root@jupiter nagios]# ps -ef | grep nagios
root     14096 13939  0 17:45 pts/0    00:00:00 grep nagios
[root@jupiter nagios]#

nagiosデーモンを起動する．

[root@jupiter nagios]# /etc/rc.d/init.d/nagios start
Starting network monitor: nagios
NAGIOS ok - status written 1 seconds ago
[root@jupiter nagios]#

プロセスを確認する．

[root@jupiter nagios]# ps -ef | grep nagios
nagios   14125     1  0 17:45 ?        00:00:00 /usr/bin/nagios -d /etc/nagios/
nagios.cfg
root     14131 13939  0 17:46 pts/0    00:00:00 grep nagios
[root@jupiter nagios]#

停止してみる．

[root@jupiter nagios]# /etc/rc.d/init.d/nagios stop 
Stopping network monitor: nagios
[root@jupiter nagios]# ps -ef | grep nagios
root     14138 13939  0 17:47 pts/0    00:00:00 grep nagios
[root@jupiter nagios]#

設定ファイルを変更した時は，reloadオプションを実行すれば良い．

[root@jupiter nagios]# /etc/rc.d/init.d/nagios reload
Running configuration check...done
Reloading nagios configuration...done
[root@jupiter nagios]#

６．監視できているか確認してみる

ログを確認する．

[root@jupiter nagios]# tail /var/log/nagios/nagios.log
[1125305644] Warning: Attempting to execute the command "/usr/lib/nagios/plugins/
check_ping -H 210.123.123.128 -w 3000.0,80% -c 5000.0,100% -p 1" resulted in a

インストールされた模様．
動作するか確認する．

[root@jupiter fping-2.4b2_to]# /usr/local/sbin/fping -h

Usage: /usr/local/sbin/fping [options] [targets...]
   -a         show targets that are alive
   -A         show targets by address
   -b n       amount of ping data to send, in bytes (default 56)
   -B f       set exponential backoff factor to f
   -c n       count of pings to send to each target (default 1)
   -C n       same as -c, report results in verbose format
   -e         show elapsed time on return packets
   -f file    read list of targets from a file ( - means stdin) (only if no -g
 specified)
   -g         generate target list (only if no -f specified)
                (specify the start and end IP in the target list, or supply a IP 
netmask)
                (ex. /usr/local/sbin/fping -g 192.168.1.0 192.168.1.255 or 
/usr/local/sbin/fping -g 192.168.1.0/24)
   -i n       interval between sending ping packets (in millisec) (default 25)
   -l         loop sending pings forever
   -m         ping multiple interfaces on target host
   -n         show targets by name (-d is equivalent)
   -p n       interval between ping packets to one target (in millisec)
                (in looping and counting modes, default 1000)
   -q         quiet (don't show per-target/per-ping results)
   -Q n       same as -q, but show summary every n seconds
   -r n       number of retries (default 3)
   -s         print final stats
   -t n       individual target initial timeout (in millisec) (default 500)
   -u         show targets that are unreachable
   -v         show version
   targets    list of targets to check (if no -f specified)

[root@jupiter fping-2.4b2_to]#

変なディレクトリにインストールされている気がするが，まぁヘルプが表示されたので動くのでしょう．
pingとして使ってみる．

[root@jupiter fping-2.4b2_to]# /usr/local/sbin/fping -A www.yahoo.co.jp
210.81.150.5 is alive
[root@jupiter fping-2.4b2_to]# /usr/local/sbin/fping -a www.yahoo.co.jp
www.yahoo.co.jp
[root@jupiter fping-2.4b2_to]#

動作している模様．　なんとなく昔？のSolarisのpingのよう．

１０．nagiosプラグインのインストール（再）

Net::SNMPと　fpingを導入し，nagios pluginを導入する前提条件が揃ったので，再度インストールする．

[root@jupiter nagios]# rpm -ihv nagios-plugins-1.4-2.1.el3.rf.i386.rpm
warning: nagios-plugins-1.4-2.1.el3.rf.i386.rpm: V3 DSA signature: NOKEY, key ID

error: Failed dependencies:

        fping is needed by nagios-plugins-1.4-2.1.el3.rf
[root@jupiter nagios]#

まだインストールできない．
条件はそろっている筈なので，強制的にインストールする．

[root@jupiter nagios]# rpm -ihv --nodeps  nagios-plugins-1.4-2.1.el3.rf.i386.rpm
warning: nagios-plugins-1.4-2.1.el3.rf.i386.rpm: V3 DSA signature: NOKEY, key ID

いろいろな管理モジュールがあるようだ．

１１．死活監視の確認

プラグインが入ったので，リロードしてみる．（根拠なし）

[root@jupiter nagios]# /etc/rc.d/init.d/nagios reload
Running configuration check...done
Reloading nagios configuration...done
[root@jupiter nagios]#

ログを確認する．

[root@jupiter nagios]# tail /var/log/nagios/nagios.log

[root@jupiter nagios]#

どうにかPINGプラグインが稼働している模様．
監視対象のmarsサーバをシャットダウン等してみる．

email;CRITICAL - Host Unreachable (210.123.123.128)

障害を検知したので，emailで通知したとログに出ている．
すると，次のようなメールがくればOK．

***** Nagios  *****

Notification Type: PROBLEM
Host: mars
State: DOWN
Address: 210.123.123.128
Info: CRITICAL - Host Unreachable (210.123.123.128)

Date/Time: Tue Aug 30 12:50:35 JST 2005

次にサーバの電源を入れてみる．

[1125373835] SERVICE ALERT: mars;PING;CRITICAL;HARD;1;CRITICAL - Plugin timed out
 after 10 seconds
[1125374395] HOST ALERT: mars;UP;HARD;1;PING OK - Packet loss = 0%, RTA = 0.20 ms
[1125374395] HOST NOTIFICATION: ujp_pc;mars;UP;host-notify-by-email;PING OK -

[1125374395] HOST NOTIFICATION: ujp_mobile;mars;UP;host-notify-by-email;PING OK -
 Packet loss = 0%, RTA = 0.20 ms
[1125374395] SERVICE ALERT: mars;PING;OK;HARD;1;PING OK - Packet loss = 0%, RTA
 = 0.24 ms

pingが復帰(UP)した事を検知し，emailで通知が送信されている．
次のようなメールが来る．

***** Nagios  *****

Notification Type: RECOVERY
Host: mars

Date/Time: Tue Aug 30 12:59:55 JST 2005

これで一通りの最低限の動作確認が終了．

１１．Webインタフェイスの設定

nagiosは標準でWebインタフェイスを持っている．
httpd.confに次のような設定を行う．

####for  Nagios
ScriptAlias /nagios/cgi-bin/ /usr/lib/nagios/cgi/
<Directory "/usr/lib/nagios/cgi">
        AllowOverride AuthConfig
        Options ExecCGI
        order allow,deny
        allow from all
</Directory>
Alias /nagios /usr/share/nagios/
<Directory "/usr/share/nagios/">
        Options None
        AllowOverride AuthConfig
        order allow,deny
        allow from all
</Directory>
#AddHandler cgi-script .cgi

とりあえずは，認証を使わないので，cgi.cfgの設定を変更する．

# Setting this value to 0 will cause the CGIs to *not* use
# authentication (bad idea), while any other value will make them
# use the authentication functions (the default).

#use_authentication=1
use_authentication=0



# DEFAULT USER
# Setting this variable will define a default user name that can
# access pages without authentication.  This allows people within a
# secure domain (i.e., behind a firewall) to see the current status
# without authenticating.  You may want to use this to avoid basic
# authentication if you are not using a sercure server since basic
# authentication transmits passwords in the clear.
#
# Important:  Do not define a default username unless you are
"cgi.cfg" 438L, 17166C written
[root@jupiter nagios]#

use_authenticationを0にしないと，CGI実行エラーとなる．

１２．StatusMapにアイコンをつける

Webインタフェイスでは，グラフィカルにサイトマップを表示する機能を持っている．
しかし，デフォルトではアイコンが？マークになっているのでこれを設定する．
まずは，cgi.cfgファイルに，hostextinfo.cfgファイルへのパスを指定する．

[root@jupiter nagios]# tail cgi.cfg         
# as these values are only used by the CGIs.  The core program 
# will read the directives you specify in a resource file.

#xdddb_host=somehost
#xdddb_port=someport
#xdddb_database=somedatabase
#xdddb_username=someuser
#xdddb_password=somepassword

xedtemplate_config_file=/etc/nagios/hostextinfo.cfg
[root@jupiter nagios]#

RPM版でインストールした場合，アイコンは/usr/share/nagios/images/logos以下に格納される．
パスは，このlogos以下で指定して，以下の様にhostextinfo.cfgファイルを定義する．

define hostextinfo{
  host_name jupiter
  icon_image base/redhat.jpg
  icon_image_alt RedHat ES3
  vrml_image base/redhat.png
  statusmap_image base/redhat.gd2
  2d_coords 700,700
}
define hostextinfo{
  host_name moon
  icon_image base/win40.jpg
  icon_image_alt Windows 2000
  vrml_image base/win40.png
  statusmap_image base/win40.gd2
  2d_coords 700,700
}

13.Basic認証をつける

サーバ構成情報が掲載されて居る為，nagiosへのアクセスはできるだけ部外者が知らない場所にあるべきである．
ここでは，BASIC認証をにて，セキュリティを保つ．
htpasswdプログラムを探す．

[root@jupiter nagios]#  locate htpasswd|grep bin
/usr/local/apache/bin/htpasswd
[root@jupiter nagios]#

パスワードファイルを作成する．
ここでは，nagiosというユーザを作成している．

[root@jupiter nagios]#  /usr/local/apache/bin/htpasswd -c /usr/share/nagios/.passwd nagios
New password: ■■■■■
Re-type new password: ■■■■■
Adding password for user nagios
[root@jupiter nagios]#

httpd.confにBASIC認証で必要な定義を設定する．

Alias /nagios /usr/share/nagios/
<Directory "/usr/share/nagios/">
        Options None
        AllowOverride AuthConfig
        order allow,deny
        allow from all
        AuthType Basic
        AuthName "Enter your name and password"
        AuthUserFile /usr/share/nagios/.passwd
        AuthGroupFile /dev/null
        Require valid-user
</Directory>

Apacheをリスタートして有効化する．

[root@jupiter nagios]# /usr/local/apache/bin/apachectl restart
/usr/local/apache/bin/apachectl restart: httpd restarted
[root@jupiter nagios]#

nagiosのページにアクセスしてみる事でパスワード認証画面が表示されれば成功となる．
