Creating an Alarm Template

An alarm template contains a group of alarm rules for a specific resource. You can use it to quickly create alarm rules for multiple metrics of a resource. Before creating a metric alarm rule by using a template, ensure that an alarm template has been created.

Precautions

You can create up to 150 alarm templates. If the number of alarm templates reaches 150, delete unnecessary templates and create new ones.

Procedure

  1. On the menu bar, choose Monitoring Center.
  2. In the navigation pane, choose Alarm Management > Alarm Rules.
  3. On the Alarm Templates tab page, click Create Alarm Template.
  4. Customize an alarm template. For details, see Table 1.

    Alarm Rules > Alarm Condition

    Metric

    Metric to be monitored.

    Consecutive Periods

    When the metric value meets the alarm condition for a specified number of consecutive periods, a metric alarm will be generated.

    Statistical Period

    Metric data is aggregated based on the configured statistical period, which can be 1 minute, 5 minutes, 15 minutes, or 1 hour.

    Statistic

    Method used to measure metrics. Options: Avg, Min, Max, Sum, and Samples.

    Alarm Condition

    Trigger condition of a metric alarm. An alarm condition consists of two parts: operators (≥, ≤, >, and <) and threshold value. For example, if the trigger condition is set to > 85 and an actual metric value exceeds 85, a metric alarm will be generated.

    Alarm Severity

    Severity of a metric alarm. Options: Critical, Major, Minor, and Warning.

    Alarm Rules

    Check Interval

    Interval at which metric query and analysis results are checked.

    • Hourly: Query and analysis results are checked every hour.
    • Daily: Query and analysis results are checked at a fixed time every day.
    • Weekly: Query and analysis results are checked at a fixed time point on a specified day of a week.
    • Custom interval: The query and analysis results are checked at a fixed interval.
    • Cron: A cron expression is used to specify a time interval. Query and analysis results are checked at the specified interval.

      The time specified in the cron expression can be accurate to the minute and must be in the 24-hour notation. Example: 0/5 * * * *, which indicates that the check starts from 0th minute and is performed every 5 minutes.

    Alarm Rules > Advanced Settings

    Alarm Clearance

    An alarm will be cleared if the monitored object does not meet the trigger condition within the monitoring period. By default, metrics in only one period are monitored. You can set up to five monitoring periods.

    Action Taken for Insufficient Data

    Action to be taken when no metric data is generated or metric data is insufficient within the monitoring period. You can set this option based on your requirements.

    By default, metrics in only one period are monitored. You can set up to five monitoring periods.

    The system supports the following actions: changing the status to exceeded and sending an alarm, changing the status to insufficient data and sending an event, maintaining the previous status, and changing the status to normal and sending an alarm clearance notification.

  5. Click OK.
