   | 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.  |

   tasks "-l {-t=s|m|h|d} {-r}"
   tasks "-s= {-t=s|m|h|d} {-r}"
   tasks "-g {-t=s|m|h|d} {-r}"
   tasks "-h {-t=s|m|h|d} {-r}"
   tasks "-n= {-r}"
   tasks "-e="

   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.
