Solaris性能與工具

內(nèi)容概要

本書全面介紹了Solaris 10和OpenSolaris中的強大工具，包括Solaris動態(tài)跟蹤工具、DTrace和MDB(模塊調(diào)試器)。書中提供了理解性能和行為的系統(tǒng)方法，包括：    ● 分析內(nèi)核和應(yīng)用程序的CPU利用率，包括讀取和理解硬件計數(shù)器。    ● 進程級資源使用和概要描述。    ● 磁盤IO行為和分析。    ● 系統(tǒng)和應(yīng)用程序級的內(nèi)存使用。    ● 網(wǎng)絡(luò)性能。    ● 內(nèi)核監(jiān)視和概要描述，以及收集內(nèi)核統(tǒng)計數(shù)據(jù)。    ● 使用DTrace提供者和聚集。    ● MDB命令和完整的MDB指南。    對任何水平的Solaris 10和OpenSolaris用戶來說，本書和《Solaris內(nèi)核結(jié)構(gòu)》都極具參考價值。
