Azure Log Analytics Data Collector - support for DCR based custom tables

I'm trying to use the Azure logic apps Send data connector to send data to a custom table.

It looks like when we give a non-existing custom table name, it creates a table and send the data.

Table is created with classic type.

When trying to send data to a DCR based custom table, logic apps send data connector operation is successfully executing, but no data is received in the table.

Logs can be sent to the custom table via log ingestion API without a problem.

My question is: is the Log Analytics Data Collector supports DCR bases custom tables?

If it's supported, do we need to do anything else to make it work?

    Hello Damith Jinasena,

    the Azure Log Analytics Data Collector doesn't support DCR-based tables, so your best option would be to use the Log Ingestion API or find a custom workaround to send data to DCR-based tables. Classic tables, however, should continue to work fine with the connector, as it supports the creation of these tables automatically.
