Error log management

This topic describes how to view and download error logs on the Database Workshop (DBW) console.

Prerequisites

An instance and account for RDS for MySQL have been created. For detailed steps, refer to Creating an instance and Creating an account.

If the target instance has security control enabled, you need to apply for operation and maintenance read-only or read/write permissions for the current account. For more information, refer to Enabling instance security control (RDS for MySQL), and Applying for operation permissions (RDS for MySQL).

Precautions

When you access the Log management tab through Operation observability on the left navigation bar, error log information about the first instance in the Instance list is viewed by default.

When downloading error logs, note the following:

A single download supports up to 10,000 log entries.

Downloaded error log files are retained for 1 day by default. Expired files will be automatically deleted. Save the downloaded files to your computer promptly.

You can view and export downloaded error log files in the export history.

Query an error log

Log on to the DBW console.

On the left navigation bar, select Operation and maintenance management > Observation and diagnosis.

On the top menu bar, select the project and region.

In the upper-right corner of the Observation and diagnosis page, select RDS for MySQL. Click the drop-down icon next to the instance name and select the target instance.

On the Observation and diagnosis page, click Log management.

Click the Error log details sub-tab and select a node in the instance to view the error log information of the node, including Collection time, Log level, and Log content. You can also filter the target error logs by time and keyword.

tip

You can filter error logs within a specified time range as needed. When selecting a time range, the query end time must be later than the start time.

Fuzzy queries are supported when you use keywords to search for error logs.
