Bill alert examples
Bill data is synchronized on a T+1 basis, so data for a given day becomes available the following day. Set the query time range to Yesterday and the check interval to one day. The following examples help you configure alerts for fees and usage.
Total fee for yesterday
Use the following query statement to alert on yesterday's total fee. Set the time range to Yesterday, the trigger condition to Data exists, and the trigger expression to "cost" > alert_threshold.
* | select
sum(PretaxAmount) as cost
FROM instance_billSingle service total fee
Use the following query statement to alert on yesterday's total fee for a specific cloud service. In the WHERE clause, replace ${ProductCode} with the target service code. Set the time range to Yesterday, the trigger condition to Data exists, and the trigger expression to "cost" > alert_threshold.
* | select
sum(PretaxAmount) as cost
FROM instance_bill
where
ProductCode = '${ProductCode}'Service usage
Use the following query statement to alert on yesterday's usage of a specific billable item. In the WHERE clause, specify the ProductCode and BillingItem. This example monitors Simple Log Service (SLS) storage usage. Set the time range to Yesterday, the trigger condition to Data exists, and the trigger expression to "Usage" > alert_threshold.
* | select
sum(Usage) as Usage
FROM instance_bill
where
ProductCode = 'sls'
and BillingItem like '%storage%'Single instance usage

* | select
sum(Usage) as Usage
FROM instance_bill
where
ProductCode = 'sls'
and BillingItem like '%storage%'
and InstanceId like '%project%'Day-over-day fee comparison
Use the following query statement to compare yesterday's fee against the previous day. Set the time range to Yesterday, the trigger condition to Data exists, and the trigger expression to "Increased by" > alert_threshold.
* |
SELECT
diff [1] AS "Yesterday's Fee",
diff [2] AS "Fee from 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
)
)
