groundcover utilizes in order to only store the traces which we believe are the most important for monitoring your environment. However, some more advanced use cases might require adjusting the sampling strategy, making sure you get the exact coverage you need.
This page details the way in which sampling can be configured.
Some cases might require 100% visibility into traces of specific services or APIs. groundcover allows forcing sampling of transactions by these methods:
HTTP/gRPC requests which include the header below will be force sampled.
Pods which have the following value as either a label and/or annotation will have all traces sampled:
The sampling mechanism can be rate limited to reduce the total amount of traces produced. Note that traces marked as issues will not be affected by this configuration.
Rate is specified by number of traces allowed per 100 milliseconds, using the following values override:
