How to read performance log file (.blg)?

[Peter]

I have generated a blg file. When I open that file, it will open Performance
and start monitoring the current activity. I can click the View Log Data
icon or Properties icon to open the System Monitor Properties window and add
the blg file in the Source tab. It seems to get the data from the blg file
but it does not get all the counters data. It seems to get only the data for
counters which are specified in the Data tab.

1. Is there a way when I open the blg file, the Performance will default to
the blg file instead of the current activity?
2. How to get all the counters data which are captured in the blg file
without adding all those counters to the Data tab MANUALLY?

The perfmon logs or data in BLG file will only capture counters you specify
while creating the counter logs.

To open the blg file, follow steps below
1) Click start>>run
2) Type perfmon and press enter
3) In system monitor cselect and remove the counters currently shown by
hitting the delete button
4) Click the fourth button that says "View log data" this button has a
cylinder icon
5) Point and open the blg file.
6) To view the log you can click the + sign button which is the 8th button
on the top. add the counters and objects that you want to view.
7) You can also adjust the graph scale by rihgt clicking inside the graph.
8) To highlight a particular counter line, select the bulb icon on the top
and click on a counter or a line in teh graph.

You can use the relog command to convert the blg files to other formats.
