nagiosのインストールがほぼほぼ出来てきたのですが、やはり見栄えがもう少し！ということで、nagiosでグラフ表示を行うことにしました。
ということで、nagiosgraphを追加します。
nagiosgraphを以下の方法でダウンロードしてきます。
|
1 2 3 4 |
# cd /home # mkdir nagiosgraph # cd nagiosgraph # wget https://downloads.sourceforge.net/project/nagiosgraph/nagiosgraph/1.5.2/nagiosgraph-1.5.2.tar.gz |
ところが、環境によってはダウンロード出来ないことがあるようです。
私の環境では、2度ほど躓きまして、結局WinSCPを使ってWindows PC転送することになりました(^^ゞ
ダウンロードが完了したら、いつもの調子で展開します。
|
1 2 |
# tar xvf nagiosgraph-1.5.2.tar.gz # cd nagiosgraph-1.5.2 |
ここまでは簡単ですねｗ
ここで、インストールの方法をWebで検索する前に、インストール方法が記載されているINSTALLファイルを覗いてみます。

# more INSTALL ------------------------ License: OSI Artistic License nagiosgraph Installation Author: (c) 2005 Soren Dossing ------------------------ Author: (c) 2008 Alan Brenner, Ithaka Harbors Author: (c) 2010 Matthew Wall Installation can be done automatically using the install.pl script, or manually by copying and modifying files. Install Pre-Requisites ---------------------- To see which pre-requisites are installed: install.pl --check-prereq To install pre-requisites: Debian/Ubuntu sudo apt-get install libcgi-pm-perl librrds-perl libgd-gd2-perl Redhat/Fedora/CentOS sudo yum install perl-rrdtool perl-GD Mac OS X Homebrew |
見てみると、install.pl –check-prereqなる文字列が・・・
インストール前の事前チェックを行う機能がnagiosgraphには備えられているようなので、取りあえず、チェックしてみます。

「FAIL」の文字が見受けられます（ＴＴ）
幾つかインストールを行う必要がありそうです。
CGIはperl-CGI
RRDsはrrdtool-perl
Time::HiResはperl-Time-HiRes
GDはperl-GDが必要です。
ということで、yumでインストール開始します。
|
1 |
# yum install perl-CGI rrdtool-perl perl-Time-HiRes perl-GD |
もう一度インストール前の確認を行います。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |

Nagios::Configの項目にFAILが見受けられます。
最新版のNagiosを使用しているので、一旦無視して作業を進めます。
インストール対象がCentOS（RedHat系）なので、以下のオプションを追加してインストールを実行します。
