IBM TotalStorage DS6000 Series: Performance Monitoring and Tuning

Chapter 9. Open system servers - Windows 339

򐂰 The Performance console can send alerts when predefined threshold levels are reached.

This is useful especially when you want to perform actions as soon as your pre-set

threshold conditions are met.

򐂰 With the Performance console, you can view special counters provided by Microsoft

BackOffice® applications. For example, when you install Exchange Server, it installs

additional object counters of its own. You can then monitor and analyze these counters

and relate them to your Exchange Server’s performance.

9.6.5 Performance Logs

The Performance Logs and Alerts window, shown in Figure 9-16, lets you collect performance

data manually or automatically from local or remote systems. Saved data can be displayed in

System Monitor or data can be exported to a spreadsheet or database.

Figure 9-16 Performance Logs and Alerts

Performance Logs and Alerts provides the following functions:

򐂰 Counter logs

This function lets you create a log file with specific objects and counters and their

instances. Log files can be saved in different formats (file name + file number, or file name

+ file creation date) for use in System Monitor or for exporting to database or spreadsheet

applications. You can schedule the logging of data, or the counter log can be started

manually using program shortcuts. Counter log settings can also be saved in HTML format

for use in a browser either locally or remotely via TCP/IP.

򐂰 Trace logs

This function lets you create trace logs that contain trace data provider objects. Trace logs

differ from counter logs in that they measure data continuously rather than at specific

intervals. You can log operating system or application activity using event providers. There

are two kinds of providers: System and non-system providers.

For system providers, the following events are provided by the Windows 2000 kernel trace

provider:

– Process creations/deletions

– Thread creations/deletions

– Disk input/output

–Network TCP/IP

– Page faults

– File details
