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