Hologres allows you to query the instance-related event logs that were generated within the last 90 days by using the ActionTrail console, calling the ActionTrail API, or using developer tools. You can also create a trail to deliver event logs to a specified Log Service Logstore or OSS bucket. This way, you can monitor events, set alert rules for events, audit events in real time, and troubleshoot issues. This topic describes how to query event logs in the ActionTrail console.

Usage notes

  • After you perform an operation on a Hologres instance, you must wait about 5 to 10 minutes before the corresponding event log is generated.
  • If you use ActionTrail to query event logs related to Hologres instances, you can query only the event logs that were generated within the last 90 days.
  • If you need to handle anomalous activities in real time, you can set alert rules for trails to monitor important events. For more information, see Use ActionTrail to monitor the use of an Alibaba Cloud account.
  • If the ActionTrail console is unavailable, you can call the ActionTrail API or use developer tools to query event logs related to Hologres instances. For more information, see API overview.
