Objective 

Prerequisites 

1. You need administrative access to the Windows Server where Eventlog Analyzer is installed.
2. It is required to simulate any synthetic read/write activity while the IOPS calculation is being done (third-party tools or scripts may be used) to make sure the IOPS value is reflective of the actual performance of the disk.

Steps to follow 

• Log in to the Windows Server in which Eventlog Analyzer is installed.
• Open the Start menu, type Performance Monitor into the search bar, and launch the application from the results
• In the left-hand pane, expand Data Collector Sets. Then, right-click User Defined and select New > Data Collector Set.

• Provide a meaningful name for the set, select Create manually (Advanced), and click Next to continue.
• Check the box for Performance Counter and then click Next to proceed.

• Click Add to open the list of performance counters.
• Select the performance counters you want to log. To monitor disk usage, look for the PhysicalDisk section and expand the list. Under this section, choose the below counters for monitoring.

• Avg. Disk Bytes/Transfer: Average disk throughput per transfer.
• Avg. Disk Queue Length: Average number of read/write requests waiting in the queue.
• Avg. Disk Sec/Transfer: Average time taken for one read/write operation.
• Disk Bytes/sec: Total disk throughput measured in bytes per second.
• Disk Transfers/sec: Number of read/write operations per second (IOPS).
• Split IO/sec: Number of split operations per second, which indicates disk fragmentation.
• Select a sample interval, which determines how often the performance counters are measured, and click Next.
• Choose a root directory where the Performance Monitor will store the collected data. Click Next to proceed
• On this page, select Start this data collector set now to begin data collection immediately. Alternatively, choose Save and close to set up the collector for running later, such as during peak hours. And click Finish to complete the data collector set creation.
• The data collector set status will display as Running.
• If you selected Save and close during setup, right-click the data collector set and choose Start to begin data collection.
• The collector will continue running until manually stopped. To halt data collection and review the results, right-click the collector set and select Stop.

• To access the report in Performance Monitor, navigate to Reports > User Defined > [Set name] > [Report name].
