By default, the Cloudbase CLI displays the most recent 20 logs. You can specify filter criteria for the returned logs by appending the following available options to the command:

-i, --reqId <reqId>  Function request Id
-o, --offset <offset>                        Data offset. Offset + Limit cannot exceed 10000
-l, --limit <limit>                        The number of records to return. Offset + Limit cannot exceed 10000
--order <order>                              Sort logs in ascending or descending order, with optional values 'desc' and 'asc'
--orderBy <orderBy>                          Sort logs by a field. Supported fields: function_name, duration, mem_usage, start_time
--startTime <startTime>                      The specific date for querying, for example: 2019-05-16 20:00:00. The time difference between startTime and endtime must be within one day.
--endTime <endTime>                          The specific date for querying, for example: 2019-05-16 20:59:59. The time difference between endTime and startTime must be within one day.
-e, --error  Return only error logs
-s, --success  Return only success logs

For example: tcb fn log app -l 2 prints the latest 2 log entries for the app function
