Alerts
The ThousandEyes platform allows you to configure highly customizable alert rules and assign them to tests, in order to highlight or be notified of events of interest.
For example, a new, start-up bank is offering internet-only accounts at competitive rates. If their system goes down, even for a short period, it could leave their customers unable to make vital payments and the bank could be penalized. Alerts allow the bank’s networking teams to be notified immediately when their tests detect any disruptive issue, thus allowing them to diagnose and fix the issue before it causes harm.
Likewise, companies in many other customer service industries such as healthcare, broadband, logistics, and energy need always-on, reliable connectivity to access medical records or keep the lights on, for example. ThousandEyes alerts enable these customers to know precisely when issues surface that threaten that stability so they can take immediate action
For those who want simplicity in alert configuration and management, the ThousandEyes platform ships with default alert rules configured and enabled for each test.
For a hands-on overview where you can configure a basic alert rule, see Getting Started with Alerts. For a more detailed guide, see Creating and Editing Alert Rules.
Assignment to Tests
Once you have created an alert rule, it can be assigned to any test that has the Enable box checked on the test configuration page (e.g., Network & App Synthetics > Test Settings > Tests for Cloud and Enterprise Agent test configuration). By default, each test has the rule "Default <test type> Rule" assigned to it. To add or remove alert rules from tests, click the pull-down menu below the Enable box, and select or deselect alert rules. Deselecting a default alert rule from a test removes the alert rule from the test, but does not stop the alert rule from being added by default to new tests. See Default Alert Rules for information about how to stop an alert rule from being added by default to tests.
To create a new alert rule, click the Edit Alert Rules link to access the Add New Alert Rule screen, and create your rule. You will then return to the test configuration page, and use the pull-down menu to assign your new rule to the test.
Alert Exclusions
In some circumstances, agents are excluded from the calculations that trigger alerts. There are two reasons this may happen.
Offline Agents
Should an agent be offline, it is unable to send data to the ThousandEyes platform. The time-sensitive alerting feature cannot therefore wait to receive its data once it's back online. Only online agents that can send live data to the platform can form part of an alert trigger calculation.
Agents with Local Problems
Cloud Agents that display a "Local Problems" message on a test results page are excluded from alert calculations.
This is the equivalent of having the alert rule's Agents field set to "All agents except" the Cloud Agent with the "Local Problems" message.
