Examples of alert rules for bills

You can set the query time range of a query statement to yesterday because bill data is synchronized on a T+1 basis. Bills of multiple cloud services are generated by day. Therefore, you must set the check frequency to a fixed interval of one day for an alert rule. The following section provides common examples of alert rules for fees and resource usage for reference. For more information, see Create an alert rule in Simple Log Service.

Create an alert rule for the total fee of the previous day

You can use the following query statement to create an alert rule for the total fee of the previous day. In the alert rule, set the Time Range parameter to Yesterday, set the Trigger Condition parameter to data matches the expression, and then enter the "cost" > Alert threshold expression.

* | select
  sum(PretaxAmount) as cost
FROM  instance_bill

Create an alert rule for the total fee of a cloud service of the previous day

You can use the following query statement to create an alert rule for the total fee of a cloud service of the previous day. In the following code, set ProductCode to the code of the cloud service that you want to monitor. In the alert rule, set the Time Range parameter to Yesterday, set the Trigger Condition parameter to data matches the expression, and then enter the "cost" > Alert threshold expression.

* | select
  sum(PretaxAmount) as cost
FROM  instance_bill
where
  ProductCode = '${ProductCode}'

Create an alert rule for the total resource usage of a cloud service of the previous day

You can use the following query statement to create an alert rule for the total resource usage of a cloud service of the previous day. In the following code, set ProductCode to the code of the cloud service that you want to monitor and set BillingItem to a billable item that you want to monitor. In this example, BillingItem is set to Storage. In the alert rule, set the Time Range parameter to Yesterday, set the Trigger Condition parameter to data matches the expression, and then enter the "Usage" > Alert threshold expression.

* | select
  sum(Usage) as Usage
FROM  instance_bill
where
  ProductCode = 'sls'
  and BillingItem like '%Storage%'

Create an alert rule for the resource usage of an instance for a cloud service of the previous day

You can use the following query statement to create an alert rule for the resource usage of an instance for a cloud service of the previous day. In the following code, set ProductCode to the code of the cloud service that you want to monitor, set BillingItem to a billable item that you want to monitor, and then set InstanceId to the resource of an instance for a cloud service that you want to monitor. In this example, BillingItem is set to Storage and InstanceId is set to a Simple Log Service project. In the alert rule, set the Time Range parameter to Yesterday, set the Trigger Condition parameter to data matches the expression, and then enter the "Usage" > Alert threshold expression.

* | select
  sum(Usage) as Usage
FROM  instance_bill
where
  ProductCode = 'sls'
  and BillingItem like '%Storage%'
  and InstanceId like '%project%'

Create an interval-valued comparison alert rule for fees

You can use the following query statement to create an interval-valued comparison alert rule for the fees of a cloud service. In the alert rule, set the Time Range parameter to Yesterday, set the Trigger Condition parameter to data matches the expression, and then enter the "Increased by" > Alert threshold expression.

* |
SELECT
  diff [1] AS "Fees of the previous day",
  diff [2] AS "Fees of the day before yesterday",
  diff [3] * 100 -100 as "Increased by"
FROM (
    SELECT
      compare(amount, 86400) as diff
    FROM (
        SELECT
          sum(PretaxAmount) AS amount
        FROM instance_bill
      )
  )
