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 Insert Company Name Here. \ 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) 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 重整網頁後選擇 工具 > 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   自訂Probes 除了內建使用fping，也可以下載Github上的 tcpping ，使用traceroute和tcptraceroute的命令，增加TCP PORT的監控 curl -o /usr/bin/tcpping -L https://raw.githubusercontent.com/deajan/tcpping/master/tcpping chmod +x /usr/bin/tcpping 測試tcpping正常 root@librenms:~# tcpping google.com 443 seq 0: tcp response from nctsaa-ac-in-f14.1e100.net (142.250.196.206) 7.402 ms seq 1: tcp response from hkg07s38-in-f14.1e100.net (142.250.204.46) 7.545 ms seq 2: tcp response from lctsaa-aa-in-f14.1e100.net (142.250.66.78) 7.399 ms   預設情況下，traceroute 需要 root 權限，所以要允許smokeping使用traceroute 建立 /etc/tcpping.conf 設定檔，並加入 -Z 參數(使用sudo) TCPPING_EXTRA_ARGS="-Z" 執行 visudo ，讓 smokeping 以 root 身分執行 traceroute 無須密碼 smokeping ALL=(ALL) NOPASSWD: /usr/bin/traceroute 編輯 /etc/smokeping/config.d/Probes ，增加tcpping + TCPPing binary = /usr/bin/tcpping   在監控設定檔內新增需要的host並指定probe和port ++ Google-https menu = Google https title = Google https probe = TCPPing port = 443 host = google.com 重啟smokeping後可以看到probe使用TCP Ping
