What this PR does / why we need it:
Which issue(s) this PR fixes:
On failed container info lookups, the container ID stored in each thread info can potentially be marked as empty. However, the
container.idfield currently reports empty container IDs ashostvalue, thus making impossible to distinguish actual threads running on the host from threads running in containers for which the metadata lookup failed.This attempts mitigating the issue by also checking that the thread is running outside of a namespace for
container.id. As such, failed container ID lookups will return an empty string instead ofhost.Special notes for your reviewer:
