Spotlight on Unix/Linux

实时诊断Unix/Linux故障

Spotlight® on Unix/Linux is a performance diagnostics and resolution tool. It graphically displays the real-time flow of data in your Solaris, AIX, HPUX, and Unix/Linux operating systems — including I/O subsystem, cache, and kernel information. 它会自动为每个系统设定正常活动的基准，用于创建阈值并发送音频或图像警告，提示即将发生的故障。 借助于Spotlight，您可以识别拥塞区域，并快速应对性能问题，以免对最终用户产生影响。

  • 通过进程和组件的图形显示，提高操作系统内部的可见度。图形显示使您能够实时观察实际的输入或输出通信量。
  • 通过实时诊断诸如前端导向器、缓存、硬盘输入或输出以及交易统计等故障区域，缩短排查故障的时间。
  • 音频或图像报警功能可识别即将发生的故障，您无需再做无谓的推测，因此有助于提高效率。
  • 借助于强大的深度诊断和快速的问题解决过程，减少最终用户的停机时间并提高生产率。
  • 通过与Foglight®集成，强化Application Performance Management解决方案。

Before installing Spotlight on Unix, ensure your system meets the following minimum hardware and software requirements:

Client Requirements

Platform

A Pentium-based or equivalent PC with:

  • A 1.2 GHz Processor (recommended minimum).
  • A monitor capable of supporting a resolution of 1280x1024 or larger. (You should also set the display to use the 64K color palette [65536 colors].)
  • A CD-ROM drive or Internet connection. Spotlight can be downloaded from the Internet or installed from compact disc. The CD-ROM drive should be attached to the PC on which Spotlight is to be installed. A drive mapped to a network device could be used if a local CD-ROM is not available.
  • A printer (optional). Spotlight reports can be printed on a laser or bubble jet printer. You can print graphs in color if your printer provides this capability.
  • A sound card and speakers (optional). Spotlight can use sound to alert you when a threshold is reached. You must have a sound card and speakers installed on your PC for this feature to work.
Memory512 megabytes of RAM (minimum). 1 gigabyte recommended. Memory consumption will increase for multiple simultaneous connections.
Hard Disk Space1 gigabyte of free disk space. This should exist on a local disk drive rather than a network drive. Extra disk space will be required if you choose to log historical snapshots from within Spotlight.
