Use: "asynqmon",
|
|
Short: "A monitoring tool for asynq queues",
|
|
Long: `Asynqmon is a CLI tool to inspect and monitor queues managed by asynq package.
|
|
|
|
Asynqmon has a few subcommands to query and mutate the current state of the queues.
|
|
|
|
Monitoring commands such as "stats" and "ls" can be used in conjunction with the
|
|
"watch" command to continuously run the command at a certain interval.
|
|
|
|
Example: watch -n 5 asynqmon stats`,
|
|
// Uncomment the following line if your bare application
|
|
// has an action associated with it:
|
|
// Run: func(cmd *cobra.Command, args []string) { },
|
|

|
|
|
// Execute adds all child commands to the root command and sets flags appropriately.
|
|
// This is called by main.main(). It only needs to happen once to the rootCmd.
