系統監控工具 Monitorix 2.4.0 發布
Monitorix 2.4.0 版本引入三個新的圖表用來監控 Squid 代理、NTP 服務器以及 Icecast 流媒體服務器。同時該版本還支持在 BSD 上監控 Nginx 網絡流量和網絡端口監控。
Monitorix 工具，這是一套可以監控系統狀態的工具，可監控的項目非常的多，你也可以自行設定要監控的服務，預設就可以分析 CPU 與記憶體使用率、磁碟存取使用率(Disk I/O Usage)、網路使用率(Network traffic and usage)、各服務使用需求(network services demand)、使用者登入的狀況、....等等。
