How to Create Alerts in Tableau
Setting up alerts in Tableau is a simple way to stay on top of your key metrics without constantly checking your dashboards. These automated notifications tell you when your data crosses a specific threshold you've defined, so you can take action right away. This tutorial will walk you through exactly how to create, manage, and troubleshoot data-driven alerts in Tableau.
What Are Tableau Alerts (and Why Should You Use Them)?
Tableau alerts are automated email notifications that trigger when a specific measure in your data reaches a certain value. Instead of manually monitoring a dashboard for changes in sales, website traffic, or inventory levels, you can have Tableau watch it for you and let you know when something important happens.
This is incredibly useful for:
Proactive Monitoring: Get notified about unexpected dips in performance, like sales dropping below a daily goal, so you can investigate immediately.
Opportunity Spotting: Set alerts for positive events, such as when a marketing campaign exceeds its lead generation target or a product's sales suddenly spike.
Exception Reporting: Keep an eye on outliers. For example, a support manager could get an alert if a customer's unresolved ticket count goes above a critical number.
Saving Time: Free yourself from the need to repeatedly check dashboards for status updates. You can trust that if something needs your attention, you'll be notified.
At their core, alerts help turn your dashboards from passive reporting tools into active monitoring systems that work for you in the background.
Before You Begin: What You Need to Create Alerts
Before you jump in, make sure you have a few things in place. Creating alerts in Tableau has some specific requirements, and checking these first will save you from hitting a roadblock later.
You must be using Tableau Cloud or Tableau Server. Alerts are a server-side feature, which means they cannot be created or managed in Tableau Desktop. You need to be working with a dashboard that has been published to your organization's Tableau environment.
You need the right permissions. To create an alert, you need to have the appropriate permissions on the dashboard or view. Typically, roles like 'Publisher', 'Site Administrator', or users with the 'Create/Edit Alerts' capability will be able to do this. If the 'Alert' option is greyed out, it's likely a permissions issue.
The view must have a continuous numeric axis. This is the most common technical hurdle. Tableau needs a continuous axis (usually a green pill for a metric like 'Date', 'Sales', or 'Profit') to check a measure against a threshold. This means alerts work on charts like time-series lines, bar charts with a continuous measure, etc., but not on discrete tables or text-based charts.
Your Tableau admin must have email subscriptions configured. Alerts are sent via email, so the Tableau Server or Tableau Cloud instance must be set up to send them. If this isn't configured, the alert feature won't work across the organization.
Step-by-Step Guide: How to Create a Data-Driven Alert
Once you’ve confirmed you have everything you need, creating an alert is a straightforward process. Let’s walk through it with an example. Imagine we have a dashboard tracking daily sales, and we want to be notified any time sales for a single day drop below $2,500.
Here’s how you’d set that up.
Step 1: Navigate to the Dashboard View
First, log in to your Tableau Cloud or Tableau Server account. Open the workbook and navigate to the specific view or dashboard where the chart you want to monitor exists. In our example, we are looking at a line chart that shows 'Sum of Sales' over time.
Step 2: Select a Continuous Numeric Axis
This is a critical step. An alert is tied to a specific metric on a specific axis. Click on the vertical or horizontal axis that represents the measure you want to track. For our sales dashboard, we would click on the vertical axis representing 'Sales'. Once selected, you'll notice the axis becomes highlighted.
Step 3: Click the 'Alert' Icon
With the axis selected, look at the toolbar at the top of the dashboard. You will see a small bell-shaped icon labeled 'Alert'. Click on it to open the 'Create Alert' panel on the right side of your screen.
Step 4: Configure the Alert Settings
This is where you define the logic for your alert. The 'Create Alert' panel gives you several options:
Condition: This is the trigger. You can choose from 'Is Above', 'Is Below', 'Is Above or Equal to', 'Is Below or Equal to', or 'Is Equal to'. Since we want to know when sales are low, we’ll select Is Below.
Threshold: This is the numeric value that triggers the alert. The field will often be pre-filled with the value of the data point you selected, but you can type in any number. We will enter 2500 here. The red line on your chart will move to a visual of where that threshold sits.
Subject: This will be the subject line of the email you receive. Make it clear and descriptive. Something like "ALERT: Daily Sales Have Dropped Below Target" is much better than "Tableau Alert". You can even use variables from your viz directly in the subject line!
Frequency: This controls how often you receive an email when the condition is met.
As Frequently As Possible: You'll get an email every time the data refresh confirms the condition is met. This is good for urgent issues.
Once per day at most: Limits notifications to once every 24 hours.
Weekly: Receive a summary of the alert at most on a weekly basis.
Recipients: By default, the alert will be sent to you. You can start typing the names of other Tableau users in your organization to add them as recipients. Remember, they must have permission to view the dashboard to receive the alert.
Step 5: Click 'Create Alert'
Once you’re happy with the configuration, click the blue 'Create Alert' button. That's it! Your alert is now active. The next time the dashboard's data is updated and the 'Sum of Sales' drops below $2,500, you and any other recipients will receive an email. The email includes a snapshot of the viz and a link to dive directly into the dashboard for more context.
How to Manage Your Tableau Alerts
Creating alerts is only half the battle. Your business priorities and data will change over time, so it's important to know how to manage the alerts you’ve set up.
To see all the alerts you own or receive, go to your Tableau Cloud or Server home page and navigate to My Content > Alerts. From this central location, you can perform several actions:
Edit an Alert: If a threshold is no longer relevant, you can select an alert and click 'Edit' to change the condition, threshold value, or frequency.
Add/Remove Recipients: You can easily update who receives an alert notification. This is helpful when team members change roles.
Pause (temporarily disable) an Alert: If you don't want to delete an alert but want to stop receiving notifications for a while, you can pause it.
Change Ownership: You can assign one of your alerts to another user if they are taking over responsibility for monitoring that metric.
Delete an Alert: If an alert is no longer needed, you can delete it permanently from this menu.
Best Practices for Creating Effective Alerts
Tableau alerts are powerful, but they can quickly become noisy if overused. Here are a few tips to ensure your alerts remain useful and actionable.
Focus on What's Actionable: Don't create alerts for "nice-to-know" vanity metrics. Set them up for KPIs that, when they change, require someone on your team to do something. Each alert should answer the question: "What will I do when I receive this?"
Set Meaningful Thresholds: Avoid setting thresholds so low or high that they trigger constantly. This leads to "alert fatigue," where people start ignoring notifications. Use historical data or defined business goals to set realistic thresholds.
Use Descriptive Subject Lines: Craft a subject line that immediately tells the recipient what happened. "ALERT: Customer Churn Today is 15%, Exceeds 5% Goal" is much more effective than a generic system message.
Keep Your Recipient List Lean: Only send alerts to the people who need to see them and can act on them. Don’t spam the entire company. A focused recipient list ensures accountability.
Conduct Regular Reviews: Your business goals will evolve. Set aside time every quarter to review your active alerts. Are they still relevant? Are the thresholds correct? Delete the ones that are no longer providing value.
Final Thoughts
Setting up alerts in Tableau transforms your dashboards from static reports into a dynamic monitoring system that actively works for your business. By defining triggers on your most important metrics, you can get ahead of problems and capitalize on opportunities faster than ever before, all without having to manually check dashboards throughout the day.
While tools like Tableau offer powerful features, we know the setup process can sometimes feel rigid, requiring you to navigate menus and understand specific technical requirements like continuous axes. That’s why we built Graphed to simplify the entire process. Instead of manually clicking through setup wizards, you can use natural language to monitor your data, asking questions like, "Show me my weekly sales vs my target" or "Tell me which campaigns have the lowest ROI." This conversational approach removes the friction, allowing you to get insights and set up performance monitoring in seconds, not hours.
