Charting aggregate method times within a PurePath

Hi Matt,

This is a perfect example of a use case for Business Transactions.  I'm not sure how familiar you are with them, so I'll be possibly a little over-specific here (please check out Dynatrace Community Webinars and APM University for more info on BTs).

1. Create a Business Transaction by right-clicking the method in the PurePath tree and clicking "Create Business Transaction"
2. First create a Methods -> Invocation Measure, giving it a relevant name and a threshold Upper Severe = 1, selecting Filter as the type
3. Second create a Methods -> Time measure, again giving it a relevant name, no need for a threshold.  Add this to the Calculate Results section, at "sum" aggregation
4. Leave the Business Transaction type as Server-side PurePath
5. Give it a name that is meaningful (this is more a suggestion), i.e. "Transactions Calling API Service" rather than "Transactions Calling API.getResponse()" for reportability
6. Apply/OK

The flow may not be exactly what's stated but if you need more direction I can record a video.  When you chart this measure from the BT, you will have the sum of the method timings per-PurePath as the data.

HTH,

Hi Matt,

You can sum up the exec time of a particular method using either simple measures, or by creating a business transaction. And you can chart those results. What you won't be able to do (can't tell if this is what you want to do from your question) is chart those results for individual PurePaths. Measure (and BT) data is inherently aggregate in nature.

Another thought: in the PurePath dashlet, one of the tabs in the top half of the screen is the "Contributors" tab. This will give you a sortable list of the methods in that PurePath. You can sort by method and see all invocations of your method all sorted together. It's not a chart, but that gives you PurePath-granularity into the execution of that method.
