Sources of Tools

• Standard tools– Tools found on UNIX systems, including HP-UX– Tools frequently found on other UNIX systems

• HP-UX-specific tools– Tools found only on HP-UX

• Optional tools– Tools licensed and sold separately

(Generally available only on HP-UX)

Summary

• Different categories of performance tools• Standard UNIX tools versus HP-specific tools• Separately purchasable tools• Kernel register-based tools versus midaemon-

based Tools


H4262S B.02

Lab

Before we continue with a more focused discussion of glance and gpm, lets spend some time exploring the generic UNIX and HP-UX-specific tools discussed so far.

As you answer the following questions, try to categorize each tool as to its type and scope.
