hostmetrics:

• process_memory_physical_usage -> process_memory_usage
• process_memory_virtual_usage -> process_memory_virtual

dockerstatsreceiver:

• Less number of default metrics: https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/dockerstatsreceiver/documentation.md

• BlockIO metrics names changed. The type of operation is no longer in the metric name suffix, and is now in an attribute. For example container.blockio.io_merged_recursive.read becomes container.blockio.io_merged_recursive with an operation:read attribute.

• Memory metrics measured in Bytes are now non-monotonic sums instead of gauges.

• Enable the container.cpu.usage.percpu metric

resourcedetection

• Remove deprecated gke/gce detectors, use gcp instead

mysqlreceiver

• mysql_commands -> mysql_prepared_statements
