The Fivetran Log Connector is a free tool that provides visibility into how users are using their Fivetran account, allowing for monitoring of instance performance, optimization of data integration costs, and control of data integration. The connector exposes log records containing sync statistics, user activities, and detailed sync information, which can be used to identify errors and troubleshoot issues. Fivetran uses the Log Connector to monitor its own demo account, which is shared with technical and sales teams and has high traffic. To prevent unnecessary infrastructure and warehouse costs, the team regularly cleans up the environment using automated scripts and tracks trends in their environment to determine where data volume comes from, what errors occur, and where those errors occur. The Log Connector is set up to write data to a specific location in the data warehouse, and role-based access controls are used to restrict access to the destination. The team uses this visibility to build a monitoring dashboard using Sigma, which provides insights into active connector count by destination, broken connectors by type, and other metrics.
