Question by Sreerag M. · May 02, 2014 at 05:49 AM ·

.Net Thread Tagging sensor creating many .ctor nodes in purepaths

Hi,

We are seeing high purepath size due to nodes created by the .Net Thread Tagging sensor. When we place the sensor we wee many .ctor nodes in the purepaths. 

Here is a screenshot of one purepath that shows the .ctor nodes. 

 

The Class of the method is System.Threading.Tasks.Task

 

We need Thread tagging for the complete tracing of the request across threads.

My question can the sensor be updated to exclude this method capture and still get the thread tagging?  or is this method need for tagging.

hi Sreerag,

we improved this in dynaTrace 5.5 and are using another method for .NET Tasks (ScheduleAndStart()) since then.
so after the upgrade these nodes will be gone. 

best, Christian

The issue we see is in v5.0.0 .

We i checked he sensor pack i could find that the v5.0.0 sensor pack has the sensor for method System.Threading.Tasks.Task.ctor() .

Where as the v5.6.0 doesn't have this method in the sensor pack. 

We are upgrading our v5.0.0 next week and will watch to see if things are ok.
