![]() Confirm you have 2-4 GB free on your c: driveģ. Download and setup scheduled Tasks via Microsoft Clue tool 1.1.6: Clue/Clue_1.1.6.zip at master Ģ. After installation, non-admin users can use the device normally and data collection will still occur even for user-initiated data collections.ġ. Requires administrator rights to install. The user can initiate a wait analysis trace to determine why Windows, or an application is hanging. Has a User-initiated trace start optimized for application hangs.High battery drains greater than 20% of battery capacity within one hour (traces CPU, GPU, and power usage).High thermal temperatures (traces CPU and power usage).High CPU by WMI (includes WMI tracing to identify the query causing it).Disk latency of greater than 25 ms for 3 or more seconds (includes high consuming processes, disk filter drivers, page file usage, and more).Kernel Pool NonPaged virtual address space greater than 10% of physical memory (indicates a driver leak in pool nonpaged).Kernel Pool Paged virtual address space greater than 10% of system committed memory (indicates a driver leak in pool paged).System Committed memory greater than 90% (indicates one or more memory leaks that are consuming the system resources).Free System PTEs of less than 50000 (kernel address space is low). ![]() Single CPU over 90% for more than 3 seconds.You can modify the config.xml to create your own scenarios, increase the data captures, and much more.Īutomatically collects a counter log and ETW trace whenever the following conditions occur: Well, those days are gone! Thanks to CLUE which runs an ETW trace in the background until a threshold found in the config.xml is hit and then automagically collects data via Tasks in Task Scheduler! This gives you a more robust view of what has occurred since the data capture shows prior to the event, and then the event in the ETW trace without manual intervention.ĬLUE was written by a Microsoft employee who has made this code open source and extensible. Performance is Complicated! It really is. You might start with a RAMMAP and a performance monitor on the first data collection, move to a pool monitor or WPR/Xperf on another collection, and then might realize you also needed a tasklist or to find which drivers were associated with which pool tags you need another set of data collected. It's frustrating when you obtain a set of data only to realize you needed an additional dataset and must perform the data capture again. Need a foolproof way for end users to capture data that isn’t too complicated?.Do customers leave data captures on too long, and the log sizes are not useful, or too large?.Intermittent issues? Reproducible issues?.Can’t seem to capture the right data at the right time?. ![]() ![]() For many years, data collection was manual, time consuming, and often labor some. I want to discuss how to perform data collection when an issue may be intermittent, troublesome to catch, ongoing, or even reproducible at will. A special thank you to Ron Stock for writing me a bad driver to use in demonstration. Does Performance Data Collection got you singing the Blues? This blog addresses how to troubleshoot High CPU and unaccounted memory usage or memory leak to include identifying and data collection using the CLUE tool written by Clint Huffman. My name is Susan Buchanan, and I am a Support Escalation Engineer with the Windows Performance Team at Microsoft. Automating Data Collection for Memory, CPU, and Disk issues ![]()
