Improvements to Azure Monitor for containers could impact your queries
Updated: December 23, 2019
The new Azure Monitor for containers agent, version ciprod12042019, introduces major improvements in resource use and data volume optimizations to help reduce costs. As part of these improvements, we’ve disabled the collection of Name and Image fields in the ContainerLog table since these fields are available in other tables. As a result, your existing queries and alerts on the ContainerLog table may be impacted. Change your queries or reenable collection for these properties.
See the documentation for more details.
