Use: "stats",
|
|
Short: "Shows current state of the queues",
|
|
Long: `Stats (aysnqmon stats) will show the number of tasks in each queue at that instant.
|
|
It also displays basic information about the running redis instance.
|
|
|
|
To monitor the queues continuously, it's recommended that you run this
|
|
command in conjunction with the watch command.
|
|
|
|
Example: watch -n 5 asynqmon stats`,
|
|
Args: cobra.NoArgs,
|
|
Run: stats,
|
|
}

// Here you will define your flags and configuration settings.

|
|
// Cobra supports Persistent Flags which will work for this command
|
|
// and all subcommands, e.g.:
|
|
// statsCmd.PersistentFlags().String("foo", "", "A help for foo")
|
|
|
|
// Cobra supports local flags which will only run when this command
|
|
// is called directly, e.g.:
|
|
// statsCmd.Flags().BoolP("toggle", "t", false, "Help message for toggle")
