LibreNMS Smokeping 安裝設定

SmokePing為開源的網路品質監控專案，LibreNMS可整合Smokeping方便監測設備


安裝Smokeping

下載Smokeping

apt-get install smokeping

複製Librenms smokeping腳本到cron

sudo cp /opt/librenms/misc/smokeping-debian.example /etc/cron.hourly/librenms-smokeping
sudo chmod +x /etc/cron.hourly/librenms-smokeping

手動執行cron一次並確認有建立檔案

/etc/cron.hourly/librenms-smokeping
ls -l /etc/smokeping/config.d/librenms-targets.conf
ls -l /etc/smokeping/config.d/librenms-probes.conf

刪除/etc/smokeping/config.d/Probes內容並新增以下

*** Probes ***

@include /etc/smokeping/config.d/librenms-probes.conf

刪除/etc/smokeping/config.d/Targets內容並新增以下

*** Targets ***

probe = FPing

menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website of <b>Insert Company Name Here</b>. \
         Here you will learn all about the latency of our network.

@include /etc/smokeping/config.d/librenms-targets.conf

建立Smokeping資料儲存位置

mkdir /opt/librenms/rrd/smokeping

由於Smokeping執行會無法寫入/opt/librenms/rrd/smokeping

須將smokeping加入librenms群組對/opt/librenms/rrd/smokeping可讀寫

chown librenms:librenms /opt/librenms/rrd/smokeping

usermod -a -G librenms smokeping

網頁上設定剛剛建立的目錄，並設定每次測試發 20 個封包

編輯/etc/smokeping/config.d/Database，修改step改為每分鐘做一次測試(預設5分鐘)

image.png

編輯/etc/smokeping/config.d/pathnames，datadir 改為上面新增的目錄

重啟smokeping

service smokeping restart

service smokeping status

確認Librenms RRD內的smokeping已有資料

網頁上Latency內已有smokeping數值

網頁 Web UI 設定

安裝 fcgiwrap 才能使 CGI 包裝器與 Nginx 互動

apt install fcgiwrap

 

 

編輯/etc/nginx/conf.d/librenms.conf設定檔加入smokeping設定

# Browsing to `http://yourlibrenms/smokeping/` should bring up the smokeping web interface

location = /smokeping/ {
        fastcgi_intercept_errors on;

        fastcgi_param   SCRIPT_FILENAME         /usr/lib/cgi-bin/smokeping.cgi;
        fastcgi_param   QUERY_STRING            $query_string;
        fastcgi_param   REQUEST_METHOD          $request_method;
        fastcgi_param   CONTENT_TYPE            $content_type;
        fastcgi_param   CONTENT_LENGTH          $content_length;
        fastcgi_param   REQUEST_URI             $request_uri;
        fastcgi_param   DOCUMENT_URI            $document_uri;
        fastcgi_param   DOCUMENT_ROOT           $document_root;
        fastcgi_param   SERVER_PROTOCOL         $server_protocol;
        fastcgi_param   GATEWAY_INTERFACE       CGI/1.1;
        fastcgi_param   SERVER_SOFTWARE         nginx/$nginx_version;
        fastcgi_param   REMOTE_ADDR             $remote_addr;
        fastcgi_param   REMOTE_PORT             $remote_port;
        fastcgi_param   SERVER_ADDR             $server_addr;
        fastcgi_param   SERVER_PORT             $server_port;
        fastcgi_param   SERVER_NAME             $server_name;
        fastcgi_param   HTTPS                   $https if_not_empty;

        fastcgi_pass unix:/var/run/fcgiwrap.socket;
}

location ^~ /smokeping/ {
        alias /usr/share/smokeping/www/;
        index smokeping.cgi;
        gzip off;
}

 

重啟Nginx

nginx -t

service nginx restart

 

網頁上URL填入/smokeping

自訂監控設定

安裝好Web UI後顯示的是Librenms監控的設備清單，可自行加入host監控

編輯/etc/smokeping/config.d/Targets，新增自訂監控設定

@include /etc/smokeping/config.d/custom.conf

 

 

編輯/etc/smokeping/config.d/custom.conf，加入想要監控的host

 

+ Others
menu = Others
title = Others

++ GoogleDNS
menu = Google DNS
title = Google DNS
host = 8.8.8.8

++ CHTDNS
menu = CHT DNS
title = CHT DNS
host = 168.95.1.1

 

確認設定正確後重啟服務

smokeping --check

service smokeping restart

 

網頁上即可看到剛剛新增的host
