Privacy policy. This Layout provides a main display with a graphic representation of performance counter data along with a legend of counters and an adjustable time window for zooming into data points.
It displays a related set of messages after you double-click a line of performance counter data for further details. Interactive Analysis This Layout for the Chart viewer is intended to work with the Perfmon Log Layout for the Analysis Grid viewer and the Perfmon Log Layout for the Grouping viewer to create an integrated and interactive analysis environment.
You will be able to correlate the data most effectively if you have these viewers and Layouts displayed. Note that these viewers and Layouts are configured in the Perfmon Logs Profile. Consider the following as an example of interactively driving the display of messages into different viewers from the Grouping viewer, which contains the following groups to organize the data:.
Streaming the data directly to a file will reduce the memory consumption of the command. I can use the continuous switched parameter to cause the Get-Counter cmdlet to stream data continuously. Because of the manual intervention required, this switch is limited to ad hoc performance testing. One would never kick off a scheduled task with the continuous switch. The modified command is shown here:. This is because I used the continuous switch.
The Export-Counter cmdlet has a maxsize parameter to limit the size of a performance log , but it does not work when the Get-Counter cmdlet is run in continuous mode. After I have finished collecting my data, I can open the. To explore the data from the performance log, I import the performance log into a variable, index into the variable, and pull out a single snapshot. Remember from yesterday , the counter set on my laptop contains more than counter paths, so for each snapshot, I have more than performance points to examine.
The data I want to work with is stored in a property called countersamples. This is where I will find the information I am interested in examining. If I want to find all counters in the first sample that contains performance points that have a cooked value that is greater than , I use the command following this paragraph.
On my laptop, quite a few counters return from the command because of the various memory counters at work my laptop has total memory that is greater than bytes. Anyway, here is a command that will return all cooked values that are greater than In this command, the [0] is used to index into the array of performance counter information, and return the first record set of data.
The curly brackets indicate a script block that is supplied to the Where-Object cmdlet:. To use Windows PowerShell to troll through the data and return useful information, it is necessary to use a compound query. In other words, I want to find counters that contain a certain word and have a certain value. For example, suppose I notice I have an issue with disk utilization. I might use a command such as the one shown here to identify all counters that contain the word logicaldisk in the path and that have a cooked value that is greater than 2.
The reason for this query is that a diskqueue length greater than 2 could be signs of a problem. The output, as shown here, is not too enlightening because of the large number of counters that relate to disk space:.
Path InstanceName CookedValue. I can now begin to filter out the information, because I have a good idea of the type of data with which I am working. I also know that many of the returned counters are returning percentages of free space, and that is a value I am not too interested in right now. The best answers are voted up and rise to the top.
