+---------------------------------------------------------------------------------------+
| tasks | Prints statistics about tasks and executions.                                 |
|       |                                                                               |
|       | Note that this command depends on GridGain events.                            |
|       |                                                                               |
|       | GridGain events can be individually enabled and disabled and disabled events  |
|       | can affect the results produced by this command. Note also that configuration |
|       | of Event Storage SPI that is responsible for temporary storage of generated   |
|       | events on each node can also affect the functionality of this command.        |
|       |                                                                               |
|       | By default - all events are enabled and GridGain stores last 10,000 local     |
|       | events on each node. Both of these defaults can be changed in configuration.  |

Arguments
-l
    List all tasks and executions for a given time period.
    Executions sorted chronologically (see '-r'), and tasks alphabetically
    See '-t=<num>s|m|h|d' on how to specify the time limit.
    Default time period is one hour, i.e '-t=1h'

    This is a default mode when command is called without parameters.
-s=<substring>
    List all tasks and executions for a given task name substring.
    Executions sorted chronologically (see '-r'), and tasks alphabetically
    See '-t=<num>s|m|h|d' on how to specify the time limit.
    Default time period is one hour, i.e '-t=1h'
-g
    List all tasks grouped by nodes for a given time period.
    Tasks sorted alphabetically
    See '-t=<num>s|m|h|d' on how to specify the time limit.
    Default time period is one hour, i.e '-t=1h'
-h
    List all tasks grouped by hosts for a given time period.
    Tasks sorted alphabetically
    See '-t=<num>s|m|h|d' on how to specify the time limit.
    Default time period is one hour, i.e '-t=1h'
-t=<num>s|m|h|d
    Defines time frame for '-l' parameter:
       =<num>s Last <num> seconds.
       =<num>m Last <num> minutes.
       =<num>h Last <num> hours.
       =<num>d Last <num> days.
-r
    Reverse sorting of executions.
-n=<task-name>
    Prints aggregated statistic for named task.
-e=<exec-id>
    Prints aggregated statistic for given task execution.
Examples
visor tasks "-l"
    Prints list of all tasks and executions for the last hour (default).

visor tasks "-l -t=5m"
    Prints list of tasks and executions that started during last 5 minutes.
visor tasks "-s=Task"
    Prints list of all tasks and executions that have 'Task' in task name.
visor tasks "-g"
    Prints list of tasks grouped by nodes.
visor tasks "-g -t=5m"
    Prints list of tasks that started during last 5 minutes grouped by nodes.
visor tasks "-h"
    Prints list of tasks grouped by hosts.
visor tasks "-h -t=5m"
    Prints list of tasks that started during last 5 minutes grouped by hosts.
visor tasks "-n=GridTask"
    Prints summary for task named 'GridTask'.
visor tasks "-e=7D5CB773-225C-4165-8162-3BB67337894B"
    Traces task execution with ID '7D5CB773-225C-4165-8162-3BB67337894B'.
visor tasks "-e=@s1"
    Traces task execution with ID taken from 's1' memory variable.
