User's Guide - Monitor - Investigate
In This Topic
The Investigate view is designed to help you understand how an Application Environment is working without necessarily focusing on resolving a particular problem (or Alert). It shows a timeline-based view of Loupe data for a single Service across multiple runs of the application - including concurrent processes used in clusters.
Investigating Web Page Performance
If there are Web Page metrics in your Loupe data (captured by the Loupe Agent for ASP.NET or other web-tracking agents), a Web Page Hits tab will show in the detail of the Investigate view. The Web Page Hits view will show the top web page hits by Duration and Volume. You can decide whether to rank Duration by Average or Percentile.
If you identify a web page that is slow, click on it to see a distribution of all of the similar page hits. From the distribution you can see if all calls are slow, or just a small subset.
Clicking on a distribution bar will select the samples in that bucket to be listed in the detail area where you can see each individual call including the details that went into the call (such as parameters used for the query).
Investigating Web API Performance
If there are Web API metrics in your Loupe data (captured by the Loupe Agent for ASP.NET or other web-tracking agents), a Web Controller Hits will show in the detail of the Investigate view. The Web Controller Hits view will show the top API operations by Duration and Volume. You can decide whether to rank Duration by Average or Percentile.
If you identify a web controller operation that is slow, click on it to see a distribution of all of the similar API calls. From the distribution you can see if all calls are slow, or just a small subset.
Clicking on a distribution bar will select the samples in that bucket to be listed in the detail area where you can see each individual call including the details that went into the call (such as parameters used for the operation).
Investigating Database Performance
If there are Database metrics in your Loupe data (captured by the Loupe Agent for Entity Framework or other database-tracking agents), a Database tab will show in the detail of the Investigate view. The Database view will show the top database operations by Duration and Volume. You can decide whether to rank Duration by Average or Percentile.
If you identify a database operation that is slow, click on it to see a distribution of all of the similar database calls. From the distribution you can see if all calls are slow, or just a small subset.
Clicking on a distribution bar will select the samples in that bucket to be listed in the detail area where you can see each individual call including the details that went into the call (such as parameters used for the query).
Data Available to Investigate
The Investigate view leverages an automatically-maintained session data index. The total amount of data in this index is the same as the session data file storage limit, however the amount of data retained will be substantially less since session data files are highly compressed.
If you find that the repository isn't keeping data long enough for your investigation needs, increase this limit.
