The command for viewing local log with formatting

Video tutorial

The local log view command is used to format and view local logs, making the logs easier to view.

$ goctls extra view_log -h
Format and view log information

Usage:
  goctls extra view_log [flags]

Flags:
  -h, --help                       help for view_log
  -l, --list                       Show all workspace configurations
  -t, --log_type string            Log Type. Use with "workspace" param. Support error, stat, access, severe, slow
  -p, --path string                Log file path. If a configuration file path is provided, the corresponding file will be read directly
  -r, --reset_workspace            Clear workspace configurations
  -s, --size int                   Number of messages to display. The default is 10, displayed in reverse order (default 10)
  -w, --workspace string           Saved workspace names
  -k, --workspace_setting string   Configure workspace data. After configuration, the workspace directory can be saved and read by name, and must be used with the log_type parameter. The format is "name,directory"

Usage

Firstly, configure workspace

goctls extra view_log -k core,D:/home/data/logs/mcms/rpc

Warning

In the example, "core" is a custom name used for differentiation in search. The comma in the middle must be an English comma, followed by a path that must contain log files such as error.log. The configuration will be saved, and multiple workspaces can be stored simultaneously, distinguished by name.

And then you can access the log by command below:

goctls extra view_log -w core -t error -s 2

Result

$ goctls extra view_log -w core -t error -s 2
