This Twilio product is currently available as a Beta release. Some features are not yet implemented and others may be changed before the product is declared as Generally Available. Beta products are not covered by a Twilio SLA. Learn more about beta product support.

Alarms for Error Logs is now available in public beta for all accounts. You can create and manage Alarms from the Monitor tab in the Twilio Console. This enhanced monitoring proactively notifies you when spikes in errors occur.

Alarms will eventually replace the existing Alert Triggers feature. We will migrate all custom Alert Triggers into Alarms when we reach general availability (expected in Q4 2022).

Getting Started

There are multiple ways to create an Alarm:

  • Directly from the Manage Alarms page.
  • From the Error Logs view, click +Create Alarm.
    View of the Error Logs page within Twilio Console, highlighting the location of the new Create Alarm button
  • From the Error Logs view, click the three dots next to an Error and select Create alarm.

After taking any of these actions, you’ll be taken to the Create Alarm page. This page allows you to configure your Alarm properties:

  • The error you are monitoring for.
  • The threshold and time period you want to check against.
  • Who gets notified when the Alarm is triggered, and how will they be notified.

Configure an Alarm

There are 4 main steps to set up an Alarm.

1. Select an Error Code to monitor

The first step is to select an Error Code from the Error code dropdown. You can configure the Alarm to monitor for a specific Error Code or for any error occurrence. The error code selection dropdown is searchable as well.

For your reference, all of Twilio’s Error Codes, with possible causes and solutions, are documented here.

Creating an Alarm from an individual error event will automatically populate the Error code field with that Error Code for you.

Once you select an Error Code, the page will display a graph showing a visual timeline of the selected error’s rate of occurrence.

2. Define the Alarm’s threshold and time period

The Alarm will be triggered when the selected Error exceeds your defined Alarm threshold within the selected Time period. You can choose from the following time boxes to allow for near real-time alerting: 5 minutes, 15 minutes, 1 hour, 12 hours, and 24 hours.

3. Configure notification preferences

The notification preferences enable you to be notified in-console, via email, or via webhook. You may select any combination of these options. Provide any necessary email addresses and/or a webhook URL if you enable either of those notification types.

The in-console notification is a red indicator displayed as a badge on the Monitoring tab.

Alarm notifications will be triggered within 15 seconds of exceeding the defined threshold.

4. Name your Alarm

Finally, give your Alarm a friendly name and click Save to activate the Alarm.

The Alarm can now be maintained from the Manage alarms page.

Manage Alarms

You can duplicate, delete, or edit any Alarm from the Manage alarms page.

Click the name of an Alarm to perform any edits, or click the three dots to display options to duplicate or delete the Alarm.

Alarms History

The Alarms history page shows a list of all triggered Alarms within your account. The Alarms history does not aggregate Alarms from subaccounts. Each account’s Alarms are independent.

Clicking into an Alarm occurrence will take you to the Alarm History detail page, which provides additional information about when the Alarm was triggered and troubleshooting steps for the Error that occurred.

Email notifications will contain a link to the Alarm History detail page, so that you can access that information quickly and directly.
