This flow shows how to create a budget, set alert thresholds, link it to a project, and get notified when spending reaches thresholds.

Execution Sample

GCP

gcloud beta billing budgets create \
  --billing-account=123456-789ABC-DEF012 \
  --display-name="My Budget" \
  --amount=1000 \
  --threshold-rules=thresholdPercent=0.5,spendBasis=CURRENT_SPEND \
  --threshold-rules=thresholdPercent=0.9,spendBasis=CURRENT_SPEND

This command creates a budget of $1000 with alerts at 50% and 90% spending thresholds.

Process Table

Step	Action	Parameter/Value	System State	Result
1	Define Budget	Name: My Budget	No budget exists	Budget object created
2	Set Budget Amount	Amount: $1000	Budget created	Budget limit set to $1000
3	Configure Alert Thresholds	Thresholds: 50%, 90%	Budget limit set	Alerts configured at 50% and 90%
4	Link Budget	Billing Account: 123456-789ABC-DEF012	Alerts configured	Budget linked to billing account
5	Activate Monitoring	Monitoring started	Budget linked	System starts tracking spending
6	Spending Update	Spending: $400	Tracking spending	No alert sent (below 50%)
7	Spending Update	Spending: $510	Tracking spending	Alert sent at 50% threshold

Key Moments - 3 Insights

Why does the alert trigger at $510 when the threshold is 50% of $1000?

Because 50% of $1000 is $500, and spending reaching $510 crosses that threshold, triggering the alert as shown in step 7 of the execution_table.

Does the budget stop tracking after reaching the limit?

No, the system continues tracking spending and sending alerts if configured, as shown in steps 9 and 10 of the execution_table.

Can multiple alert thresholds be set for one budget?

Yes, multiple thresholds like 50% and 90% can be set, and alerts will trigger independently as spending crosses each, as shown in step 3 and alerts in steps 7 and 8.

Visual Quiz - 3 Questions

Look at the execution_table, what alert is sent when spending reaches $920?

A 50% threshold alert

B 90% threshold alert

C 100% threshold alert

D No alert

💡 Hint

Check row 8 in the execution_table where spending is $920 and alert sent is noted.

At which step does the budget get linked to the billing account?

A Step 4

B Step 3

C Step 2

D Step 5

💡 Hint

Look at the 'Action' and 'Result' columns in the execution_table for linking budget.

If the budget amount was changed to $2000, how would the 50% alert spending value change?

A $500

B $1500

C $1000

D $2000

💡 Hint

50% of the budget amount triggers the alert; see variable_tracker for spending and thresholds.

- Alerts sent when spending crosses thresholds.
- Monitoring continues until budget is deleted or reset.

Full Transcript

This visual execution trace shows how to configure budget alerts in Google Cloud Platform. First, you define a budget and set its maximum amount. Then, you configure alert thresholds, for example at 50% and 90% of the budget. Next, you link the budget to a billing account so the system knows which costs to track. Once activated, the system monitors spending and sends alerts when spending reaches or exceeds the thresholds. Spending updates trigger alerts at the configured points, and monitoring continues even after the budget limit is reached. This helps users stay informed and control cloud costs effectively.

Practice

1. What is the primary purpose of setting a budget alert in Google Cloud Platform?

easy

A. To block all services when budget is exceeded

B. To automatically increase your budget limit

C. To notify you when your spending reaches a certain threshold

D. To create a backup of your billing data

Solution

1. Step 1: Understand budget alerts function

   Budget alerts are designed to notify users when spending approaches or exceeds set limits.

2. Step 2: Identify the correct purpose

   Among the options, only notification at spending thresholds matches the budget alert purpose.

3. Final Answer:

   To notify you when your spending reaches a certain threshold -> Option C

4. Quick Check:

   Budget alerts = notify spending threshold [OK]

Hint: Budget alerts notify spending limits, not block or increase budget [OK]

Common Mistakes:

• Thinking budget alerts block services automatically
• Assuming budget alerts increase budget limits
• Confusing budget alerts with data backup

2. Which of the following is the correct way to specify a budget threshold alert at 50% of the budget in a GCP budget configuration?

easy

A. "thresholdRules": [{"thresholdPercent": 50}]

B. "thresholdRules": [{"thresholdPercent": 0.5}]

C. "thresholdRules": [{"thresholdPercent": 1.5}]

D. "thresholdRules": [{"thresholdPercent": 5}]

Solution

1. Step 1: Understand thresholdPercent format

   In GCP budget config, thresholdPercent is a decimal representing the fraction of the budget (e.g., 0.5 for 50%).

2. Step 2: Match correct decimal for 50%

   0.5 equals 50%, so "thresholdRules": [{"thresholdPercent": 0.5}] is correct; 50 or 5 are invalid as they exceed 1.

3. Final Answer:

   "thresholdRules": [{"thresholdPercent": 0.5}] -> Option B

4. Quick Check:

   50% = 0.5 decimal [OK]

Hint: Use decimals (0.5) not whole numbers (50) for thresholdPercent [OK]

Common Mistakes:

• Using 50 instead of 0.5 for 50%
• Setting thresholdPercent greater than 1
• Confusing percentage with decimal format

3. Given this budget alert configuration snippet:

{"amount": {"specifiedAmount": {"currencyCode": "USD", "units": "100"}}, "thresholdRules": [{"thresholdPercent": 0.8}]}

At what spending amount will the alert trigger?

medium

A. $80

B. $8

C. $100

D. $180

Solution

1. Step 1: Identify budget amount

   The budget amount is $100 as specified by "units": "100" in USD.

2. Step 2: Calculate alert trigger amount

   The thresholdPercent is 0.8, meaning 80% of $100, which equals $80.

3. Final Answer:

   $80 -> Option A

4. Quick Check:

   80% of 100 = 80 [OK]

Hint: Multiply budget by thresholdPercent decimal to find alert amount [OK]

Common Mistakes:

• Confusing units with cents
• Using thresholdPercent as 80 instead of 0.8
• Selecting full budget amount instead of threshold

4. You configured a budget alert with this JSON snippet:

{"thresholdRules": [{"thresholdPercent": 1.2}]}

Why does this configuration fail to send alerts?

medium

A. thresholdPercent must be a string, not a number

B. thresholdPercent must be an integer

C. thresholdRules must be empty for alerts to work

D. thresholdPercent cannot be greater than 1 (100%)

Solution

1. Step 1: Check thresholdPercent valid range

   thresholdPercent must be between 0 and 1, representing 0% to 100% of budget.

2. Step 2: Identify invalid value

   1.2 is 120%, which is invalid and causes alert failure.

3. Final Answer:

   thresholdPercent cannot be greater than 1 (100%) -> Option D

4. Quick Check:

   thresholdPercent ≤ 1 required [OK]

Hint: Keep thresholdPercent ≤ 1 to avoid alert failures [OK]

Common Mistakes:

• Using values above 1 for thresholdPercent
• Assuming thresholdPercent must be integer
• Leaving thresholdRules empty disables alerts

5. You want to receive budget alert notifications via email and also trigger an automated workflow using Pub/Sub when spending reaches 90% and 100% of your $200 budget. Which configuration approach is correct?

hard

A. Set two thresholdRules at 0.9 and 1.0, configure email notifications and add a Pub/Sub topic for alerts

B. Set one thresholdRule at 0.95, configure only email notifications, no Pub/Sub needed

C. Set thresholdRules at 90 and 100, configure Pub/Sub only, email alerts are automatic

D. Set thresholdRules at 0.9 and 1.0, but Pub/Sub topics cannot be used for budget alerts

Solution

1. Step 1: Define multiple thresholdRules correctly

   Use decimal values 0.9 and 1.0 for 90% and 100% thresholds.

2. Step 2: Configure both email and Pub/Sub notifications

   Email alerts require notification channels; Pub/Sub topics can be added to automate workflows.

3. Final Answer:

   Set two thresholdRules at 0.9 and 1.0, configure email notifications and add a Pub/Sub topic for alerts -> Option A

4. Quick Check:

   Multiple thresholds + email + Pub/Sub = correct setup [OK]

Hint: Use decimals for thresholds; add email and Pub/Sub for alerts [OK]

Common Mistakes:

• Using whole numbers instead of decimals for thresholds
• Assuming Pub/Sub cannot be used with budget alerts
• Configuring only one threshold for multiple alerts
