Tencent-SCF - Logs

Lets you watch the logs of a specific function deployed in Tencent Cloud.

serverless logs -f hello

# Optionally tail the logs with -t
serverless logs -f hello -t

Options

  • --function or -f The function you want to fetch the logs for. Required
  • --stage or -s The stage you want to view the function logs for. If not provided, the plugin will use the default stage listed in serverless.yml. If that doesn't exist either it'll just fetch the logs from the dev stage.
  • --region or -r The region you want to view the function logs for. If not provided, the plugin will use the default region listed in serverless.yml. If that doesn't exist either it'll just fetch the logs from the ap-guangzhou region.
  • --startTime A specific unit in time to start fetching logs from (ie: 2019-7-12 00:00:00 ).
  • --tail or -t You can optionally tail the logs and keep listening for new logs in your terminal session by passing this option.
  • --interval or -i If you choose to tail the output, you can control the interval at which the framework polls the logs with this option. The default is 1000ms.

Examples

Note: There's a small lag between invoking the function and actually having the log event registered in Tencent Cloud Log Service. So it takes a few seconds for the logs to show up right after invoking the function.

serverless logs -f hello

This will fetch the logs from last 10 minutes as startTime was not given.

serverless logs -f hello -t

Serverless will tail the function log output and print new log messages coming in starting from 10 seconds ago.
