-When `Exec['apt_update']` is triggered, it will generate a `Notice` message. Because the default [logging level for agents](https://docs.puppet.com/puppet/latest/configuration.html#loglevel) is `notice`, this will cause the repository update to appear in logs and agent reports. Some tools, such as [The Foreman](https://www.theforeman.org), report the update notice as a significant change. By setting the [loglevel](https://docs.puppet.com/puppet/latest/metaparameter.html#loglevel) metaparameter for `Exec['apt_update']` above the agent logging level, one can eliminate these updates from reports:
