This chapter describes the relationship between WATCH and the OpenVMS MONITOR utility.
The Monitor Utility (MONITOR) is a system management tool supplied by Digital. It enables you to obtain information on operating system performance. It provides summary and detailed information about a vast array of system performance indicators. WATCH is a supplement to the MONITOR utility. It does not in any sense replace it.
WATCH condenses critical performance indicators from eight separate MONITOR screens onto a single screen. Only the important fields are present and their representation is as meaningful as possible. It also provides information such as response time and files open that MONITOR doesn't provide. Finally, it provides detail information about large numbers of processes, information about disks, and information about single processes on a single screen. Use WATCH to identify the problem area. Then use MONITOR to gather detail information and review it offline. Together, they form a potent system tuning facility.
