WPA: Table & Graph Configurations (Part 2)
In Part 1, we discussed the different types of columns options available in WPA's table views and how those views can be configured. This blog will continue the series by digging into how to configure columns for different graph styles that can show numeric aggregations, time, and hierarchical data: Graphing Overview Before we dive into how to configure the tables and graphs, we should do a quick introduction to the Group & Graph bars in WPA's tables. Any column in the Data Area or Graphing Element Area can be aggregated (see Part 1 - Aggregation). Aggregated columns are graphed wh...

The error can be frustrating, especially when there is enough memory and storage space left on the system. Some people try to solve the issue by increasing the system resources such as killing some apps and services. It does not help. I agree. It is frustrating to see generic error messages like this which can mean many things. Let us find out what causes this error and how to resolve the situation. Cases where WPR throws ERROR_NO_SYSTEM_RESOURCES error This insufficient system resource er...

Windows Performance Analyzer – Table & Graph Configurations (Part 1)
In the previous post, we discussed a brief intro into Windows Performance Analyzer (WPA) and its feature set. WPA can display trace data in a wide array of formats, most of which are pre-configured as presets designed for drilling into specific data points. Here is one for example: WPA's CPU Usage (Sampled) table has a few different presets, each reconfigures the view of both table and graph data. This blog post is the first of a multi-part series that goes into detail on how to configure the table and graph views to create your own presets: Column Options Depending on the column's da...
