Cluster Log Management

Overview

Cluster logs are collected and sent to Log Tank Service (LTS). You can check or dump the collected cluster logs on LTS.

Currently, the following log types are supported:

  • CN logs

  • DN logs

  • OS messages logs

  • Audit logs

  • CMS logs

  • GTM logs

  • Roach client logs

  • Roach server logs

  • Upgrade logs

  • Scaling logs

Note

  • Cluster log management depends on LTS.

  • Only 8.1.1.300 and later versions support cluster log management.

  • Only 8.3.0 and later versions support CMS logs, GTM logs, Roach client logs, Roach server logs, scaling logs, and upgrade logs.

Enabling LTS

  1. Log in to the GaussDB(DWS) management console.

  2. Choose Clusters > Dedicated Cluster. All clusters are displayed by default.

  3. Click the name of the target cluster. Choose Logs.

    Note

    • If LTS has been enabled and authorized to create an agency, no authorization is required when LTS is enabled again.

    • By default, only cloud accounts or users with Security Administrator permissions can query and create agencies. IAM users under an account do not have the permission to query or create agencies by default. Contact a user with that permission and complete the authorization on the current page.

    • When interconnecting with LTS, you need to grant LTS-related permission policies (LTS Admin, LTS Administrator, LTS FullAccess, and LTS ReadOnlyAccess) to users.

  5. Check the LTS status.
