試下Prometheus & Promdash

一樣是類似之前用的OpenNMS或是Cacti或是StatsD

在該目錄下也有許多xxxx_exporter可以將資訊提供給不同的介面作展示

當然現在很方便的是，也有許多用Docker的印像檔可以直接用，不用作"環境"設定

我的閒置機是Ubuntu

Linux ubuntu 4.2.0-16-generic #19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

首先，依此導讀檢查是否有備齊相關套件

因為有.deb套件

所以可以使用編譯好的組件

請先加入來源至系統的 /etc/apt/sources.list

然後直接更新、安裝即可

或是偷懶的話也可以使用 aptitude install 也行，會自動幫你做掉相關套件

完成的話

預設訪問畫面(正常是倒數第二張圖，這是Grafana)

看一下log

2016/07/07 10:45:56 [error] 737#0: OCSP_basic_verify() failed (SSL: error:27069076:OCSP routines:OCSP_basic_verify:signer certificate not found) while requesting certificate status, responder: ocsp.int-x3.letsencrypt.org

竟然有滿滿的錯誤

這是使用了 letsencrypt 的ssl

解決方式很簡單

修改一下 Nginx config

ssl_certificate  /etc/letsencrypt/live/boredom.gotdns.com/cert.pem;

變成

ssl_certificate  /etc/letsencrypt/live/boredom.gotdns.com/fullchain.pem;

就完成了

再來另一個錯誤 (Joomla 3.2)  似乎也可透過升級解決!

FastCGI sent in stderr: "PHP message: PHP Warning:  session_start(): Failed to decode session object. Session has been destroyed in /boredom.gotdns.com/libraries/joomla/session/session.php

進到Joomla 目錄  vi ./cli/finder_indexer.php

JFactory::getApplication('site');
$_SERVER['HTTP_HOST'] = 'domain.com';

把這兩行"順序"對調即可

$_SERVER['HTTP_HOST'] = 'domain.com';
JFactory::getApplication('site');
