Prerequisites

In the folder where the executable file is located, run the fcli shell command to enter the interactive mode.

Run the logs command to query logs

Run the logs command to query logs.

  • -c int or --count int: sets the maximum number of returned rows of the log content. Default value: 1000.
  • -d int or --duration int: specifies the duration in which function logs are returned. Unit: seconds. Default value: 86400.
  • -e string or --end string: sets the end of the time range to query logs. Specify the time in the RFC3339 format. The time must be in UTC, such as 2017-01-01T01:02:03Z.

// In the corresponding service directory
logs myFunction // By default, return the first 1,000 rows of the log content of the day.
logs -d 60 -c 5000 myFunction // Return the log content for function execution within 1 minute. A maximum of 5,000 rows of the log content can be returned.
logs -t -c 100 myFunction // Return the last 100 rows of the log content.
logs -s 2018-01-22T18:00:00Z -e 2018-01-22T19:00:00Z myFunction // Return the log content generated from 18:00:00 to 19:00:00 on January 22, 2018.
