1. Introduction
TTYWatch is a program that maintains statistics on selected system resources and events.
As a Cedar component, Watch is described by TTYWatch.df. The tool is named TTYWatch.bcd.
For client programs that need information that Watch gathers, some of the more interesting numbers are exported through WatchStats.
Watch places a relatively small load on most machines (less than 2% on a Dorado). Its load can further be decreased by increasing the sample interval. The tool displays the CPU load in the MP of the processor. This porgram does not work correctly if loaded in addition to the Watch tool.
