FunctionGraph is interconnected with LTS, allowing you to view function logs without the need for any configurations.
On the FunctionGraph console, view function logs in the following ways:
After creating a function, test it and view test logs on the execution result page, as shown in Figure 1. For details, see Test Management.
The execution result page displays a maximum of 2 KB logs. To view more logs of the function, go to the Logs tab page.
Figure 1 Test logs

On the Logs tab page, you can query all logs and their contexts, and view only error logs by selecting Show error logs only. You can also enable LTS to manage function logs. For details, see Querying Logs.
After querying the logs of a function version within a specified date range, you can download the logs for further analysis.
A maximum of 5000 logs can be downloaded at a time. When querying logs, select a proper time range to avoid the loss of logs.
