Configuring the Threshold

Updated at: Mar 25, 2021 GMT+08:00

Scenarios

You can configure monitoring indicator thresholds to monitor the health status of indicators on FusionInsight Manager. If abnormal data occurs and the preset conditions are met, the system triggers an alarm and displays the alarm information on the alarm page.

Procedure

  1. Log in to FusionInsight Manager.
  2. Choose O&M > Alarm > Thresholds.
  3. Select a monitoring indicator for a specified host or service in the cluster.

    Figure 1 Configuring indicator thresholds
    For example, after selecting Host Memory Usage, the information about this indicator threshold is displayed.
    • If the alarm sending switch is displayed as , an alarm is triggered if the alarm threshold is reached.
    • The alarm ID and alarm name contain the alarm information that is triggered by the threshold:
    • FusionInsight Manager checks whether the value of each monitored indicator reaches the threshold. If the number of consecutive check times is equal to the value of Trigger Count, and the threshold is not reached in these checks, the system sends an alarm.
    • The value can be customized. Check Period (s) indicates the interval for the system to check monitoring indicators.
    • Rules for triggering an alarm.

  4. Click Create Rule to add rules used for monitoring indicators.

    Table 1 Monitoring indicator rule parameters

    Parameter

    Value

    Description

    Rule Name

    CPU_MAX (example value)

    Name of a rule.

    Alarm Severity

    • Critical
    • Major
    • Minor
    • Warning

    Alarm Severity

    • Critical
    • Major
    • Minor
    • Warning

    Threshold Type

    • Max value
    • Min value

    You can select the maximum or minimum value of an indicator. Setting this parameter to Max value, the system generates an alarm when the actual value of the indicator is greater than the threshold. Setting this parameter to Min value, the system generates an alarm when the actual value of the indicator is less than the threshold.

    Date

    • Daily
    • Weekly
    • Others

    This parameter is used to set the date when the rule takes effect.

    Add Date

    09-30

    This parameter is available only when Date is set to Others. You can set the date when the rule takes effect. Multiple options are available.

    Thresholds

    Start and End Time: 00: 00 to 08:30

    This parameter is used to set the time range when the rule takes effect.

    Threshold: 10

    Specifies the threshold of the rule monitoring indicator.

    For the last parameter in the table, you can click or to add or delete multiple start and end time or alarm indicator thresholds.

  5. Click OK to save the rules.
  6. Locate the row that contains an added rule, and click Apply in the Operation column. The value of Effective for this rule changes as Yes.

    You can apply a new rule only after clicking Cancel.

Monitoring Indicator Reference

FusionInsight Manager alarm monitoring indicators are categorized into node information indicators and cluster service indicators. Table 2 describes the indicators whose thresholds can be configured on nodes.
