If an existing blacklist policy does not meet your business requirements, you can modify the blacklist policy.

Procedure

  1. Log on to the CloudMonitor console.
  2. In the left-side navigation pane, choose Alerts > Alert Blacklists.
  3. On the Alert Blacklists page, find the blacklist policy that you want to modify and click Edit in the Actions column.
  4. In the Create/Edit Blacklist Policy panel, change parameter settings for the blacklist policy. The following table describes the parameters.
    Parameter Description
    Name

    The name of the blacklist policy.

    Instances The IDs of instances that belong to the specified cloud service. Separate multiple instance IDs with commas (,).
    Metric The metrics of the specified cloud service.
    • If you add a metric, the blacklist policy takes effect only for the metric. Click the add (+) icon in the Metric section to add a metric. Repeat this step to add multiple metrics.
    • If you do not configure this parameter, the blacklist policy takes effect for all metrics.
    Note CloudMonitor allows you to create blacklist policies only based on threshold metrics. You cannot create blacklist policies based on system events.
    Specify Effective Time Range The time range in which the blacklist policy is effective.
    • If you select Specify Effective Time Range, you must specify a time range. The blacklist policy is effective only in the time range that you specify. Valid values:
      • Absolute Time Range: The blacklist policy is effective only in the time range that you specify. You must specify the start time and the end time of the time range.
      • Relative Time Range (Daily Cycle): The blacklist policy is effective in the specified time range every day. You can also specify the start date and the end date of a date range in which the blacklist policy is effective.
    • If you do not configure the Specify Effective Time Range parameter, the blacklist policy is permanently effective.
    Note You can specify only one time range for each blacklist policy. If you want the same blacklist policy to be effective in multiple time ranges, you must create multiple blacklist policies and specify different time ranges for the blacklist policies.
    Effective Scope The effective scope of the blacklist policy. Valid values:
    • User: The blacklist policy takes effect only for the current Alibaba Cloud account.
    • Group: The blacklist policy takes effect only for the specified application groups. If you select this option, you must specify one or more application groups.

      Make sure that one or more application groups are created. For more information, see Create an application group.

  5. Click OK.
