This topic describes how to modify an alarm configuration through using the example of updating the statement associated with the alarm.


  • An alarm can be associated with two types of statements: search statements and search-and-analysis statements. After you associate a statement of either type with an alarm, you can only update the statement as a new version of the same type, rather than one of the other type.

    For example, after you associate the request_method: GET search statement with an alarm, you can change it to error ( search statement), but you cannot change it to error| select count(1) as c(search-and-analysis statement).

  • For more information about how to modify an alarm configuration of an earlier version, see Upgrade an alarm configuration to the latest version.

  • If you want to modify an alarm configuration of the latest version, you can click Modify on the Alarm page, or choose Alarm > Modify on the dashboard page where the charts associated with the alarm is added.
