NOTE:

Enter local time for "to_time".

The value is in the format of "year-month-day/hour:minute:second", where:

number=?

Number of alarms that you want to query. When you specify this parameter, you can query a specific number of latest alarms.

The value is an integer ranging from 1 to 10000.

Usage Guidelines

  • The allowed query period ranges from 2000-01-01/00:00:01 to 2035-12-31/23:59:59 in UTC.
  • If too many alarms are displayed, press "q" to stop and exit the display.
  • "sequence" and other parameters are mutually exclusive and cannot be used at the same time. Except that in the developer view, "sequence" can be used together with "alarm_state".
  • The "alarm_state" and "root_cause_sequence" can be used in the developer view only.
  • When alarms are queried in the developer view, parameter "Alarm State" will be displayed.
  • When the "sequence" parameter is used in the developer view and the child alarms are queried, the "Root Cause Sequence" will be displayed.

Example

  • Query all the system alarms.
