Simple Log Service:Monitor and audit Simple Log Service

Last Updated:Sep 11, 2026

Simple Log Service provides a service log feature and integrates with CloudMonitor to monitor and audit your enterprise data.

Service logs

The service log feature of Simple Log Service records various log data in a project, such as user operation logs, and provides dashboards for multi-dimensional analysis. You can use this feature to monitor the service status of Simple Log Service in real time and improve operations and maintenance (O&M) efficiency.

All log data generated in the current project is classified and saved to specific Logstores. By default, the following two Logstores are created:

  • internal-diagnostic_log: Records consumer group latency, Logtail heartbeat logs, and task operational logs, distinguished by topic. Retention: 30 days (fixed). Free of charge.

  • internal-operation_log: Records one log entry per request. Default retention: 30 days (modifiable). Billed the same as a standard Logstore.

For more information, see Service logs.

CloudMonitor

You can use CloudMonitor to monitor Simple Log Service metrics, such as write traffic, overall queries per second (QPS), and service status. You can also create alert rules to monitor for exceptions in log collection and shard usage.
