Description

Some attributes of target_info may be repeated and separated by colons. Also, if I turn off target_info, it will delete the target_info I generated on the client side.

Steps to Reproduce

Use java-auto-instrumentation and use prometheus exporter。 The metric list will contain the target_info metric by default. AND then Enabling target_info in prometheusremotewrite will cause the label in the final target_info metric to be repeated. However, if target_info is turned off, there will be no target_info in the output metric list.
