This is an excellent initiative, — proactively detecting and managing AppSheet failures is key to providing professional-grade service. Here’s a structured response addressing your four points with best practices and creative techniques from the AppSheet and no-code communities:
â‘ Methods for Detecting Failures
A. Manual & Passive Monitoring
Check AppSheet Status Page: Updated by AppSheet/Google for platform-wide issues.
Join AppSheet Community Forum: Issues often appear here before official status updates.
Google Workspace Admin Console (if using AppSheet with Workspace): Occasionally reflects broader outages.
B. Client Behavior Monitoring
Client Issue Logs: Encourage clients to report issues through a form (AppSheet or Google Form) with automatic timestamping and context.
Anomaly in App Usage: Use AppSheet Audit Log (Enterprise plans) to track usage drop-offs, errors, or failed syncs.
② Methods for Gathering Detailed Information about Failures
A. AppSheet Audit Logs
Enterprise-only feature but very powerful: logs every sync, error, and change.
Shows error messages, user actions, and sync success/failures.
B. Automation Failures
In AppSheet Automation > Monitor > Bots:
Review failures, their step-by-step logs, and error messages.
Helpful to identify broken expressions or outages in integrations (e.g., email, webhooks).
C. Google Apps Script Logs
If using GAS with webhooks or time triggers, enable logging:
console.log("Received data: ", JSON.stringify(e));
Use Stackdriver / Apps Script Execution Logs to trace issues.
D. Google Sheets Logs
Track when AppSheet modifies the sheet (via App Scripts or Sheets version history).
Use Apps Script to log Last Row Timestamp for key tables.
③ Notifications from AppSheet Regarding Failures
A. Built-In Notifications
Automation Failures: Send email or Slack notifications when a Bot or Task fails.
AppSheet shows a red error in Monitor > Bots, but not real-time unless you set notification actions.
B. Status Page Notifications
Subscribe to status.appsheet.com to receive emails about outages or downtime.
④ Creative Approaches Using GAS or Automation for Failure Detection
Here are some creative, reliable setups used by AppSheet pros:
Example 1: Heartbeat Table + Apps Script Watchdog
-
AppSheet Bot: Every 5–15 minutes, add/update a row in a Heartbeat table.
-
Apps Script: Run every 10–20 minutes:
function checkHeartbeat() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(“Heartbeat”);
var lastRow = sheet.getLastRow();
var lastTime = sheet.getRange(lastRow, 1).getValue();
var now = new Date();
var diff = (now - lastTime) / 1000 / 60; // in minutes
if (diff > 15) {
MailApp.sendEmail(“your@email.com”, “AppSheet Failure Detected”, No heartbeat in ${diff} minutes.);
}
}
Example 2: Log User Sync Failures via Feedback Form
Create a button in the app: “Report Sync/Crash Issue.”
Users can report problems with details (device, action, issue).
Trigger a Slack/email notification to support team.
Example 3: Monitor Sheet Updates from AppSheet
AppSheet Bot writes to a Log sheet.
Apps Script periodically checks for timestamp changes.
If not changed within threshold, send alerts.
Example 4: Multiple App Test Accounts
Create 1–2 test user accounts that simulate regular user activity (scheduled automation, random reads/writes).
If those fail or don’t sync for X time, you can deduce a larger issue is at play.
Bonus Tools
Slack or Discord Integration for real-time alerts.
Zapier to connect logs/errors with notification systems.
UptimeRobot (with webhook ping) to monitor specific AppSheet APIs or webhooks you expose.
