+---------------------------------------------------------------------------------------+
| disco | Prints topology change log as seen from the oldest node.                      |
|       | Timeframe for querying events can be specified in arguments.                   |
|       |                                                                               |
|       | 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 DISABLED and GridGain stores last 10,000 local     |
|       | events on each node. Both of these defaults can be changed in configuration.  |

Specification
disco
disco "{-t=s|m|h|d} {-r} {-c=}"
Arguments
-t=<num>s|m|h|d
    Defines timeframe for querying events:
       =<num>s Events fired during last <num> seconds.
       =<num>m Events fired during last <num> minutes.
       =<num>h Events fired during last <num> hours.
       =<num>d Events fired during last <num> days.
-r
    Defines whether sorting should be reversed.
-c=<n>
    Defines the maximum events count that can be shown.
Examples
disco
    Prints all discovery events sorted chronologically (oldest first).
