Instant Logs-Edge Security Acceleration(ESA)-阿里云帮助中心

Instant Logs is a lightweight and easy-to-use log service that allows you to view logs for Functions and Pages in real time in the console. You can use the data from Instant Logs to understand the execution status of your functions and make adjustments to Functions and Pages accordingly.

Limitations

Each Functions and Pages instance can have only one active monitoring window at a time. The maximum duration for a single monitoring session is 60 minutes.
Instant Logs can store a maximum of 40 records per session. Records are sorted in reverse chronological order, and new records overwrite the oldest ones when the buffer is full.

Start monitoring

Log on to the ESA console. In the left-side navigation pane, choose Edge Computing > Functions and Pages.
On the Edge Function page, click the name of the target function, or click View Details in the Actions column of the function.
Select Logs > Instant Logs > Start Monitoring to start collecting logs.
- Click to view the detailed fields for a specific log record.
- Click in the upper-right corner to download the log data as a JSON file.
- If you switch function pages during monitoring, the monitoring is stopped and the history is cleared. You need to manually click Start Monitoring again to start Instant Logs.

Stop monitoring

Log on to the ESA console. In the left-side navigation pane, choose Edge Computing > Functions and Pages.
On the Edge Function page, click the name of the target function, or click View Details in the Actions column of the function.
Select Logs > Instant Logs, and click Stop Monitoring, , or to stop the monitoring window and log collection.
Note
The collected log history remains visible on the page. Clicking Start Monitoring again appends new logs to the history.
