  • Microsoft SQL Server versions 2017, 2019
  • Azure SQL
  • Amazon RDS for SQL Server

Configuration

edit

When using the build a connector workflow, intially these fields will use the default configuration set in the connector source code. Note that this data source uses the generic_database.py connector source code.

Refer to mssql.py for additional code, specific to this data source. These configurable fields will be rendered with their respective labels in the Kibana UI. Once connected, users will be able to update these values in Kibana.

The following configuration fields are required to set up the connector:

host

Sync rules

edit
  • Permissions are not synced. All documents indexed to an Elastic deployment will be visible to all users with access to that Elastic Deployment.
  • Filtering rules are not available in the present version. Currently, filtering is controlled by ingest pipelines.

Connector client operations

edit

End-to-end testing

edit

The connector framework enables operators to run functional tests against a real data source. Refer to Connector testing for more details.

To perform E2E testing for the Microsoft SQL connector, run the following command:

make ftest NAME=mssql

For faster tests, add the DATA_SIZE=small flag:

make ftest NAME=mssql DATA_SIZE=small
