Strategic Guidance on LogMart Usage

LogMart is a legacy database component from a previous architecture. While it remains supported for specific, pre-existing reporting needs, it is not recommended for new deployments or use cases.

Key Considerations

  • Performance: LogMart was not designed for high-volume data forwarding and can become a performance bottleneck, especially for unique logs that do not aggregate well. As a best practice, disable log forwarding to LogMart by default.

  • Limited Use Case: LogMart’s only intended function is historical, count-based reporting at the log source level. It should not be used for operational monitoring, health checks, or performance analysis.

  • Future Direction: The long-term product strategy is to retire LogMart in favor of modern, indexer-based analytics and the Metrics-API. You should prioritize using native dashboarding and reporting tools for all new analysis.

As of LogRhythm SIEM version 7.23, LogMart is a legacy component slated for future retirement. It is not recommended to build new processes that rely on LogMart. If you have a specific reporting need, enable forwarding only for the precise classification types required and for logs that will aggregate well.
