Percona Toolkit使用之pt-summary
阿新 • • 發佈：2019-01-05
pt-summary的功能是優雅地彙總系統資訊。
用法如下：
pt-summarypt-summary方便地彙總伺服器的狀態和配置。它並不是一個調優工具或者診斷工具。它生成一個易於diff以及可以不丟失格式貼上進Email的報告。該工具在很多型別的Unix系統上執行良好。
pt-summary執行大量命令去檢查系統狀態和配置，儲存輸出到臨時目錄檔案，然後在這些結果上執行Unix命令來優雅地格式化。以特權使用者執行時它工作得最好，當然也可以在沒有特權時執行，不過非root使用者可能無法生成某些輸出。
該工具的很多輸出都刻意舍入來展示其量級大小而不是具體細節。這稱為“fuzzy-rounding”。該設計思想為一個特定的計數是918還是921並沒有關係；如此小的差異是微不足道的，只會讓輸出結果難於同其他伺服器作比較。fuzzy-rounding隨著輸入的增長會舍入更大的增量。它剛開始舍入到最近的5，然後是最近的10，最近的25，然後以10倍大小的因數重複（50,100,250），隨著輸入的增長，以此類推。
以下是一個生成自CentOS虛擬機器的簡單報告，以註釋分割成段落。在終端作為手冊頁查閱該文件時，為了明晰，一些長行被重新格式化。
該段展示當前日期和時間，以及伺服器和作業系統的概覽。
