以前に Docker で Smokeping を起動するというメモを書きました。 今回は Docker を使わず、CentOS7 上に直接、Smokeping をインストールする手順をメモしておきます。
インストール
epel からインストール可能です。
# yum info smokeping

Summary : Latency Logging and Graphing System
URL : http://oss.oetiker.ch/smokeping/
License : GPLv2+
Description : SmokePing is a latency logging and graphing system. It consists of a
: daemon process which organizes the latency measurements and a CGI
: which presents the graphs.yum でインストールします。 フロントエンドになる Web サーバ (Apache) もインストールしておきます。
yum -y install httpd smokepingSmokeping と Apache を起動します。 自動起動設定もしておきます。
systemctl enable smokeping.service
systemctl start smokeping.service
systemctl enable httpd.service
systemctl start httpd.service設定ファイルのカスタマイズ
Probes 定義部分を見ると、Smokeping は初期設定で ICMP (Ping) 監視に fping を利用していることが分かります。 HTTP 監視用に /usr/bin/curl を追加します。 設定変更後の設定ファイル (/etc/smokeping/config) 例は以下の通りです。
