# Setting Up Alerts Alerts notify you when something needs attention. Set up rules for any metric and receive notifications through email and in-app alerts. ## Creating an Alert [#creating-an-alert] ### Step 1: Navigate to Alerts [#step-1-navigate-to-alerts] 1. Go to your domain's dashboard 2. Click **Alerts** in the sidebar 3. Click **Create Alert** ### Step 2: Configure the Rule [#step-2-configure-the-rule] | Field | Description | | ------------- | ----------------------------------------- | | **Name** | Descriptive name for the alert | | **Module** | Which monitoring type (RUM, Uptime, etc.) | | **Metric** | Specific metric to monitor | | **Condition** | Comparison operator | | **Threshold** | Value that triggers the alert | | **Window** | Time period to evaluate | | **Severity** | Info, Warning, or Critical | ### Step 3: Set Notification Channel [#step-3-set-notification-channel] Choose how to receive alerts: * In-app notifications (always enabled) * Email notifications (optional, toggle per alert) ### Step 4: Save and Activate [#step-4-save-and-activate] Click **Create Alert** to activate your rule. ## Alert Configuration [#alert-configuration] ### Modules [#modules] Choose which monitoring type to create alerts for: | Module | Configuration | | ------------------------- | -------------------------------------------------------------------------------------------------- | | **RUM** | Custom metrics: LCP, CLS, INP, TTFB, FCP (p75 values), Error Rate | | **CrUX** | Custom metrics: LCP, CLS, INP, TTFB with URL/Origin and device filter | | **Synthetic** | Custom metrics: LCP, CLS, TBT, TTI, FCP, SI, TTFB, Network Requests with URL and evaluation window | | **Uptime** | Predefined alerts: Site down/up, SSL expiry, domain expiry | | **Robots.txt** | Predefined alerts: Syntax errors, sitemap blocking, file changes | | **Google Search Console** | Percentage-change metrics: Clicks, Impressions, CTR, Discover, News | | **Indexing** | Percentage-change metrics: page counts per coverage state | | **Web Analytics** | Percentage-change metrics: Visitors, Sessions, Pageviews, Bounce Rate, and more | | **Google Analytics** | Percentage-change metrics: Users, Sessions, Engagement Rate, and more | ### Predefined Alerts (Uptime & Robots.txt) [#predefined-alerts-uptime--robotstxt] For Uptime and Robots.txt modules, select from predefined alert types: **Uptime Alerts:** * Site is down * Site is up (recovery) * SSL will expire in 14/7 days * Domain will expire in 14/7 days **Robots.txt Alerts:** * Robots.txt file changed * Robots.txt has syntax errors * Robots.txt blocks sitemap URLs ### Device Filter (RUM, CrUX & Synthetic) [#device-filter-rum-crux--synthetic] For RUM, CrUX, and Synthetic alerts, you can filter by device type: | Device | Description | | ----------- | ------------------------------ | | **Any** | Combined data from all devices | | **Phone** | Mobile devices only | | **Desktop** | Desktop computers only | ### Evaluation Window (Synthetic Only) [#evaluation-window-synthetic-only] For Synthetic alerts, choose how many recent tests to evaluate: | Window | Description | | ------------------ | ---------------------------- | | Last test only | Alert on single test result | | Average of last 3 | Smoother, reduces noise | | Average of last 5 | More stable baseline | | Average of last 10 | Most stable, slower to react | ### Conditions (Custom Alerts) [#conditions-custom-alerts] For RUM, CrUX, and Synthetic modules, configure threshold conditions: | Operator | Description | | --------- | ---------------------------------------------------------- | | `>` | Greater than | | `<` | Less than | | `>=` | Greater than or equal | | `<=` | Less than or equal | | `=` | Equals | | `!=` | Not equals | | `changed` | Value changed (Uptime and Robots.txt boolean metrics only) | For Google Search Console, Indexing, Web Analytics, and Google Analytics, alerts compare the current period against the previous one using percentage-change operators: | Operator | Description | | -------------------------- | --------------------------------------------------------------------------- | | Decreased by more than (%) | Metric dropped by more than X% vs. the previous period | | Increased by more than (%) | Metric rose by more than X% vs. the previous period | | Anomaly (std. deviations) | Metric deviates from its rolling average by more than N standard deviations | These operators require a **comparison window** (1, 3, 7, 14, or 28 days). ### Severity Levels [#severity-levels] | Level | When to Use | | ------------ | ------------------------- | | **Info** | Non-urgent, good to know | | **Warning** | Needs attention soon | | **Critical** | Immediate action required | ## Example Alerts [#example-alerts] ### Site Down Alert (Predefined) [#site-down-alert-predefined] Select from Uptime module: * **Alert Type**: Site is down * **Severity**: Critical (preset) * **Email**: Enabled ### Poor LCP Alert (Custom) [#poor-lcp-alert-custom] | Setting | Value | | --------- | --------- | | Module | RUM | | Metric | LCP p75 | | Condition | `>` | | Threshold | 2500 (ms) | | Severity | Warning | ### SSL Expiring Soon (Predefined) [#ssl-expiring-soon-predefined] Select from Uptime module: * **Alert Type**: SSL will expire in 14 days * **Severity**: Warning (preset) * **Email**: Enabled ### CrUX Performance Alert (Custom) [#crux-performance-alert-custom] | Setting | Value | | ---------- | ----------------- | | Module | CrUX | | Metric | LCP p75 | | URL/Origin | Origin (all URLs) | | Device | Any | | Condition | `>` | | Threshold | 2500 (ms) | | Severity | Warning | ### Synthetic Monitoring Alert (Custom) [#synthetic-monitoring-alert-custom] | Setting | Value | | ----------------- | ----------------- | | Module | Synthetic | | Metric | LCP | | URL | Homepage | | Device | Any | | Evaluation Window | Average of last 5 | | Condition | `>` | | Threshold | 2500 (ms) | | Severity | Warning | ## Managing Alerts [#managing-alerts] ### View All Alerts [#view-all-alerts] See all configured alerts at **Domain** → **Alerts**: * Alert name * Module badge * Enabled/disabled toggle ### Edit an Alert [#edit-an-alert] 1. Click the alert row 2. Modify settings in the modal 3. Click **Update Rule** ### Disable an Alert [#disable-an-alert] Toggle the switch next to any alert to enable or disable it without deleting. ### Delete an Alert [#delete-an-alert] 1. Click the trash icon next to the alert 2. Confirm deletion ## Quick Setup [#quick-setup] For new domains, use **Create essential alerts with one click** to set up recommended alerts across every module. This creates alerts for: * RUM: LCP, CLS, INP (p75 thresholds) * CrUX: LCP, CLS, INP (Origin, any device) * Synthetic: LCP, CLS (Home URL, average of last 5) * Uptime: Site down/up, SSL expiry (14/7 days), Domain expiry (14/7 days) * Robots.txt: Syntax errors, sitemap blocking, file changed * Google Search Console: Clicks and Impressions dropped > 30% (7-day) * Indexing: Indexed pages dropped > 15% (7-day) * Web Analytics: Visitors dropped > 30% (7-day) * Google Analytics: Users dropped > 30% (7-day) ## Best Practices [#best-practices] ### Start with Critical Alerts [#start-with-critical-alerts] Begin with the most important alerts: * Site down * SSL expiring * Critical performance thresholds ### Avoid Alert Fatigue [#avoid-alert-fatigue] Too many alerts lead you to ignore them: * Use appropriate thresholds * Set reasonable evaluation windows * Group related alerts ### Test Your Alerts [#test-your-alerts] Verify alerts work: 1. Create a test alert with a low threshold 2. Confirm notification is received 3. Delete the test alert ### Use Severity Appropriately [#use-severity-appropriately] Reserve Critical for truly urgent issues: * Site completely down * Security issues * Revenue-impacting problems ### Review and Refine [#review-and-refine] Periodically review your alerts: * Are you getting too many? * Did you miss important issues? * Are thresholds still appropriate? ## Related [#related] Detailed alert types by module Configure notification channels
